Hard Point Handle Question
« on: June 12, 2010, 06:23:11 PM »
I know there is currently a HP Handle thread going, but I didn't want to side track that one.

OK, as I have said before, I haven't flown since 1975 and am gathering equipment and supplies to resume the hobby.

Hard Point handles are a new concept to me.  When did they become popular and who made the discovery that they were superior to the Hot Rock style?

Hard Point handles are a new concept to me.  When did they become popular and who made the discovery that they were superior to the Hot Rock style?

    They became popular in the early 2000's when Ted started making them, and I started telling people on the internet how much better control response they have compared to Baron handles. A Hot Rock has better control response than the Baron, but the hard point is better. There weren't a lot of people still using Hot Rocks at that time because they aren't adjustable for spacing (the overhang is fine). Except for Howard, and he found a different issue with his...

   Ted got the idea from Paul Walker's handle, that he noticed at the 1994 World Champs.

The hard point handle instantly made me a better pilot. The controls are so much more positive than the cable type handles. The only drawback is netural adjust is not quite as easy as a Hot Rock style. A small price for the much better control feel.

After reading this I think I don't know what a hard point handle is. I guess a cable handle is one which has cable emerging from the handle, possibly the cable can be slid to adjust level? And hard point?

A hard point handle has holes for the line clips to attach to.  Only way to adjust neutral is to use different length line clips.

     Au contraire! Or at least not necessarily. Paul's original version, that's true. On Ted's design, and the Brodak/Godzilla version, the line carriers can be slid in and out to adjust neutral a small amount. It also changes the overhang but you only need a tiny degree of adjustment once you get it close (I vary around +- 1/64-1/32" to correct any tendencies I have developed). I have only used standard clips with mine. It will actually adjust a lot more than that but you don't want to since it also changes the overhang.   Although I really like Randy's "Hello Kitty" clips, I haven't actually used them.

Ah so,  go to the hobby shop, get a set of Perfect cable lines, a couple of packs of Perfct connectors and a E-Z Just Hot Rock handle.  I even had the big Hot Rock handle for combat.  The Perfect clips were okay as long as you remembered to center the slide closer.

Hobby shop?  What hobby shop, LOL!  I gave up flying when I moved in '76 because there was no hobby shop.  However, if I wanted RC cars to play with, there would be no problem.

Thank you gentlemen.

Next question - why should one be superior to the other? (assuming overhang and line spacing is the same?).

Overhang and Line spacing are two different animals.  Line spacing is the actual distance between the flying lines measured at the handle.  Over hang is the distance from the center line of the grip to the attachment (pivot) point of the lines to the handle.

Brett help me out here, you can explain it clearer that I just did.  A picture or drawing would help.

Cable handles are kinda springy: to wit, airplane control deflection varies more with differential line tension than it does with a hard handle.  Also, if you fly a lot with a Hot Rock handle at one adjustment setting as you do in stunt, the cable will fatigue where it turns the corner at the top or bottom, and your airplane will be annihilated. 

I thought it was interesting that the hobby shops Doc goes to have Hot Rock handles, but then I remembered that the last time I went to the same shops, they had Hot Rock handles (and Dooling engines and Veco kits and Tornado wood props).

  Because the hard point is far less compliant. I didn't think it mattered, either, until I tried it. Going from my Baron handle with 1/16 aircraft cable cables, to the Ted handle, was about equivalent from going from .015 stranded to .014 solid lines - which is quite substantial. Switching back felt like I was flying with rubber bands - every control input lagged behind and had to be anticipated, the airplane tended to "hop" exiting corners, etc. And I had been pretty good, even nationally competitive, with that. You can sort of compensate for it with a lot of practice but getting rid of the control compliance makes it so much easier it's ridiculous.

They say a picture is worth 1,000 words.

Here is a picture of one of my handles for scale flying but it is a Hard point handle.  Note the selection of holes to adjust the line spacing.  The two bolts in each end can be removed to adjust the overhang and then reinstalled.

 I just tried my first Hard Point this weekend. I did this to try and ween myself off of solid lines. I have been using solids since 1995 and I am getting tired of all the upkeep. I have been flying the new plane with braids and the hard point handle; The turn responce is good but I am still getting a lot of extra drag from the lines that I am not use to. I don't think I would like it at all if I were using a cable handle.

I'm still flying cables, but I have had two handle cable breaks from bending fatigue on a TD 09 airplane.  So it is not the pull, but the wiggle around a stress point that does them in.  I now look at my handle cables before flying.

If you go to a hardpoint handle (Ted/Carl unit is my favorite), you just about have to make your own line clips to get the adjustability you need. Most the guys I fly with have their "Ted"  handles glued up solid at minimum overhang. Mine, too.  Jim Lee (Lee's Machine in the Vendor's section or at VSC) makes the "Derek Moran" clip bender...and sells the stainless wire, too. Highly recommended combination of Kewl Cottage Industry Products! Once you try it, you'll never like a cable handle again. I do suggest making clips from "stock" (Sullivan/Brodak) length to + 3/8" at max. Even I can make my lines equal length within that range, tho I buy most mine from Jim Snelson at CLC. They're closer than I can do, because my yard sucks for tying up lines...not flat enough. Not long enough for F1A towlines, either!

Here's a pic of my simple gluing jig for the TED handle kits. I used a drill press, to drill the pine chunk to a snug push fit for some 8P nails...works perfectly! Where the nails go isn't critical...you just push the laminations into the corner, like a V-block. If the handle gets glued to a nail, twist the nail to break the glue loose.  I use thick slow CA for laminating, and finishing epoxy for the finish. Most guys use tennis racket grip tape or fishing rod handle wrap to improve the grip. This is fishing rod stuff, 'cause I fish.  n~ Steve

You should be able to read Carl Shoup's contact info on the picture. Nice stuff, you'll like it. There is a small and a large size. The small is a duplicate of the Hot Rock, while the large is, um, like bigger. Not sure it's the same as the large sized Hot Rock, but I don't think so. The idea is to work it to make it fit your hand, anyway. The small one works nicely for me. Ted can measure you with a handshake, if you happen to meet him. Worked for me!  LL~ Steve

Two things I'd like to make clear.  Although I did market the handle kit originally, the basic idea was stolen from Paul Walker after the 1994 World Champs in Shanghai.  I carried his handle a lot that trip and noticed the hard point style and the fundamentally proper symmetry of the Hot Rock.  Paul's was non adjustable so I can take some credit for "discovering" the in/out adjustment so that small (repeat, small) neutral adjustments can be made more easily.

Second, the larger version is (IIRC) about 1/2 inch greater grip length.  The "big" Easy-just was a full one inch greater than the Hot Rock and unless you're Sasquatch it is probably too large for you to fly stunt with as the "arms" that contain the line clips will be too far apart to touch the top of your index finger and the bottom of your pinkie.  These "touching arms" are an integral part of the Precision Pro handle concept as they allow tiny turn adjustments to be made with small pressure on the arms by those two fingers.  I don't think there are many fliers who will need anything wider in spacing than the large version.

I should note that Carl is responsible for the innovation of the longer line clips that allow much increased spacing options than my originals.

Other than that I second most everything that's been said about the advantages (and the few disadvantages) of the hard point style.  I'm partial to my own design and I expect Godzilla is partial to his.  Mr. Walker doesn't need me to sell his original version.  The bottom line is probably both work just fine.

Should add that the killa deal is 4ea. for $100, including shipping. If you're into note keeping, it is possible to use one handle (glued up solid & unadjustable) for multiple planes, but most prefer to keep one handle & line set for each plane.   y1 Steve

Just a couple of comments about "overhang" because it is the least obvious of the characteristics of a handle for flying precision maneuvers.  But first a story...

Back in the start of the enlightened age of stunt, Bobby Hunt came to the '74 Nats with his in-flight adjustable handle that had no spacing or overhang adjustment but could have the neutral adjusted in flight with a worm gear arrangement.  Helpful, but, obviously, a far try from the variety of adjustments soon made available with the Bob Baron style handle--which was a huge step forward to the ultimate stunt handle (IMHO).

Bobby Hunt's handle was also unique in that the two arms (with roughly four inch spacing...I could go measure mine if I could find it in the mess that used to be my shop) were something like two and half or three inches long.  In addition, the arms were angled a number of degrees to allow the infamous "relaxed as in shaking hands" neutral position.  The craftsmanship was Bobby Hunt beautiful and the in-flight neutral adjustment seemed like a great idea at the time so a number of us from the Bay Area snapped a few up.  This was, literally, the start of my fascination with handles and their impact on the quality of flight trim for stunters. 

We went home and promptly went out to fly with our new super handles.  Gary McClellan and I were at the field the first day; Gary with his Max .35S Nobler and me with the original Moby Dick.  What follows is not made up!

Both of us on our first flights pancaked the airplanes on the inverted pull outs of the first wingovers.  Fortunately we were flying over grass and the only significant damage was to the props.  We were able to fly again and be more cautious as we entered the new realm of Bobby Hunt handles.  After only a couple of complete flights we quickly came to the realization that the feel of these long armed handles was significantly different with much more effort required to input a pitch change and dramatically increased tendency of the system to return to neutral.  It only took a little thought to recognize that we should have predicted exactly that response with only a tiny bit of consideration of the physics involved.

I promptly took mine home and shortened the arms  (very carefully with a dremel cutter because the were made of some pretty substantial type of plastic)to approximate the Hot Rock I'd been flying with since I was about ten and went out to fly again.  Now the response rate was very similar but I ultimately gave up trying to use the handle as the biased neutral was simply too difficult for me to adapt to. 

Shortly thereafter the terrific Bob Baron style handle (the bar in front of the grip with adjustable spacing, overhang and neutral) became available sold by Gene Martine.  This concept had great merit and I immediately went through another series of flying sessions evaluating it.  The adjustability was a no "brainer immediate love affair".  This handle, however, had no Hot Rock style "arms" above and below the grip and I found I had great difficulty "massaging" corners to get flat bottoms and appropriate angles to corners.  Again, upon going back to my original Hot Rock, the reasons became obvious.  The patterns immediately returned to the quality I expected and I now felt the pressures I had been subconsciously applying with my pinky and index fingers to those arms.  I then modified the Baron/Martine handle with arms top and bottom so it again felt like a Hot Rock but had all the adjustability of the stock item.

Finally, the pertinence to this discussion.  Simply gluing the line attachment clips into the arms into a Fancher handle eliminates one of the tuning mechanisms built into the design; the ability to adjust the overhang (modestly) so as to vary the "feel" of control inputs; i.e. how much effort it takes to initiate a response and how much help the system gives to return that input back to neutral.  Some fliers are fingertip types (myself included) and need very little feedback from the system because they use mostly small muscle inputs to achieve the desired response.  I believe this to be the best approach to precision flying but others would disagree.  The hard point connection makes inputs much more positive and an individual who uses large muscle groups to make inputs might find the combination of short arms and hard point connection feels too sensitive to his personal preference for inputting commands.  By moving the attachment clips out further to increase the "overhang" such preferences can be accommodated...a positive version of my negative response to the long arms on the Hunt handle.

The bottom line is that I wouldn't advise users to immediately glue the line clips in place until they've fine tuned the airplane to which a given handle will be dedicated.  Overhang variation is a "modest" adjustment feature but one that shouldn't be overlooked as you fine tune your airplane to your preferences.  What is important about it however is that the difference in overhang should be as minimal as possible (which is why it is important to tie your lines at consistent lengths so as to minimize the need to have a dozen different length line connectors).  If you use overhang differences between the up and down lines to "trim" out turn differentials inside versus outside you're doing the wrong thing.  This merely masks an aerodynamic trim issue with the airplane which should be resolved at the airplane.  (This goes for varying the up versus down line spacing as well, by the way). 

IMHO, biasing the handle in any manner from essentially symmetrical (i.e. you could hook it up upside down and still fly a decent pattern with it) is not in the best interests of your competitive standing.  The classic example of a handle set up exactly correctly was demonstrated at last month's Northwest Regionals when Pete Peterson took off with his handle connected backwards.  He quickly realized what had happened and switched the handle upside down as the airplane was performing its unexpected loop after launch.  After recovering his composure he proceed to fly a very competitive pattern with the handle upside down.  The only way you could tell it was upside down was because the safety thong was now attached to the "up" line.

OK, enough pontificating.  It's Sunday, go out and enjoy whatever handle you enjoy flying with.

Ted,  I want to thank you for the input on the handle.  It has opeed my eyes to the possibilties that I have not even thought of yet.  My Accentor is flown with just one handle and has been since I first started flying it.  The P-39 is going to get the newest F-Handle if the Thunderbolt doesn't get finished.  Last time out I started out with my set(lines & handle) for the Arctic Fox.  Put up some decent patterns for me and then switched to the F-Handle.  What a difference.  Ready for Topeka I thought but, I guess I didn't put enough flights on it.  Pulled into the RW and thought I had nailed the inverted pullout.  Plane went about 10 feet and went almost straight in from about 6-7 alt.  I felt the jerk (not me) on the handle just before it went down.  I discovered on disection of the remains is that the pushrod joint between the flaps and elevator had slipped.  Even tho I couldn't budge the joint on the shop.  There was about 10 degrees between the surfaces from neutral.  In other words neutral flap had over 10 degrees of up.  Anyway thanks to whom ever invented the F-Handle.  Just need to get some more from Carl.

   I hadn't heard that one before. Sorry you crashed but, you know, that's pretty funny!
    Bob told a related story on himself back in the days he was doing the FM column. He and Billy are out flying. Billy flies his airplane, and shouts from the center of the circle that something must be broken!  Bobby goes out, takes the handle, no, everything is normal. Turns out it's so nose-heavy that Billy thinks something is wrong.

Thought maybe some of you might like to see my rendition of a stunt handle.  This uses the clevices by the moon Bro.s.   It has no bias and is fully adjustable.  This handle reduces stress on my hand and forearm. I have been using this concept handle for several years now and the design has lived up to my expectations.

One thing not mentioned so far is the mass of the handle. I find that very important to "feeling" the plane. The lighter, the better.  It in the same realm as free controls and clean lines. It maximizes your control over the plane.

I have replaced the metal in the handle with carbon fiber.  The bottom line is that the handle weighs 35 grams, including the line clips.  That's just over 1 ounce.  If you don't think that's light, put yours on a scale!

I'm still working to get it lighter, yet still stand up to the pull test.

Here's another option in the hardpoint handle: Brodak recently brought out two versions designed by Brad Walker.  The large (item BH-364) is roughly the same as a large EZ Just, the small (item BH-363) is comparable to the Hot Rock.  They have a textured lastic grip - big improvement over the slippery plastic.  Adjustable line spacing and adjustable arm lengths for fine tuning neutral like Ted mentioned.  They also weigh considerably more than 35 grams.

I am one of those dinosaurs who actually LIKES the long armed handles with offset (or lack of offset depending on your POV!)  but even dinos evolve (maybe).  I have the small Brodak/Walker Handle, and one of Jim Lee's clip bending fixtures.  What I do not have is a round tuit, but when I find one of those I still hope to try the new handle later this year to see what all the excitment is about...

When the Brodak/Brad handle first became available, we had 3 guys using them. They all use TED handles now. Those B/B handles are about 4 oz. My TED handles are right at 60 grams, with no effort to save weight. About half, and very noticeable. Seems to me that the weight of the handle would matter more the lighter the plane & lower line tension.  Mike Haverly has been making CF versions of TED handles for a few years. Not sure if the arms are adjustable or not. Keith Varley has been making his own version with aluminum arms, balsa grip, very little plywood, and no overhang adjustment. Try something new...you will probably like it!  y1 Steve

  . . .  Most the guys I fly with have their "Ted"  handles glued up solid at minimum overhang. Mine, too.  . . .
  . . .


Steve --

Do you know what the minimum overhang measures? -- Face of handle grip to clip attachment hole? That's on the Ted / Shoup handle, of course.
       The perspective in the pics makes it difficult to make a good guess. (I'm re-doing some old handles, and decided to bring the overhang to "Ted" specs at the same time)

When ever a handle thread comes up I post this one atempting to find out more about it.

The new and improved Hot Rock!!!
Well its 40-50 years old, is same dimension as small Hot Rock.

Say's it is the 'Italian'(the red one)

Cast Aluminum construction with thumb wheel up/dn adj. Very usable and good ratio on adjustment.

Anyone ever seen one?
No one knows where it came from other than it was in a box of junk.

If Ted were to use this handle, there would need to be a green stripe next to the position indicator slot to tell him if his handle setting is OK.

Howard
Does it have to be green?

Mostly fly by myself and never sure about the nutral setting until flying(Cant see no mo)
When I'm lucky the wife tell me if its at neutral and that can be +or- 10% up or down and then adjust it in the air.
I currently use the same handle on 5-6 different airplane as they are all being trimmed and sorted so this lets me keep fine tuning back to neutral after changes.

The handle does work well, if I feel that neutral hand has me to high or low just a small flick of the thumb wheel makes it right!

Sorry for the slow reply, Larry. Musta missed it.  I just ran down and measured my offishul TED handle....1.20" (+/-/.010" or so). Truth is, mine are not (yet) glued solid, but they have never been moved from minimum overhang, and I doubt that they will be. I'm gittin' ready to stick another two or four together, and might just glue these up solid. I can see that a lot of o'hang would be oppressive, and don't see how minimum can be a problem, but when TED speaks, I listen. PW, too. Howard, not so much... LL~ Steve

I just tried my first Hard Point this weekend. I did this to try and ween myself off of solid lines. I have been using solids since 1995 and I am getting tired of all the upkeep. I have been flying the new plane with braids and the hard point handle; The turn responce is good but I am still getting a lot of extra drag from the lines that I am not use to. I don't think I would like it at all if I were using a cable handle.

HI Derek,

You did move the leadouts back an 1/8 to 1/4 inch when you went to the bigger lines, didn't you?  The drag issue relative to the bigger lines is largely resolved by putting the leadouts in the right place to allow the ship to fly at the same tangency to the circle arc as it did with the smaller diameter lines.  If they're in the right spot the primary remaining issue is the power necessary to deal with the extra drag.

Having said that, there is no question that the solid lines under ideal conditions will provide superior performance.  Whether the increase is measurable from the judges' perspective and whether it outweighs the downside elements of maintenance and the occasional unexpected "stickiness" in a bottom right corner then becomes the issue.  To say nothing of waking up at three in the morning in the midwest and looking out the motel window to see if it was raining and, when it was, not being able to go back to sleep worrying about water, solid lines and will they or won't they....stick, that is.  On the left coast we've pretty much unanimously determined the overall negatives outweighed the technical and theoretical positives.

I remember one big meet (nats or TT) where I had just such a stick in the third corner of a triangle early in the week, barely saved the airplane and couldn't fly a decent pull out for the rest of the week...started early every time and tried to "finesse" a bottom.  You can imagine how that worked out, right!

That's fascinating!  I've never seen one of those before.  Almost looks like it was a modified Hot Rock, except for the word "Italian" on the grip.  Very strange.

Steve,

Overhang is certainly in the "flyer's preference" realm.  In fact, technically, the overhang isn't accurately measured from the front of the grip but from the axis of rotation of the hand...the wrist, to be precise.  Overhang provides a significant amount of "feel" to the system as well as the natural tendency to "caster" or return to neutral when displaced.  It is a "real" factor but one that I feel is a legitimate place for personal preference; something I don't believe applies to things like biased spacing or neutrals (I know, I know.  I lot of guys disagree but that's what makes the world go round).

However, if you consider extremes of of overhang it can have a dramatic impact.  Think of two wild extremes.  First say the arms are maybe three feet long.  Depending on how much line tension you have you may not be strong enough to deflect the controls enough to fly a loop, let alone a full pattern.  It would be like trying to lift twenty pound on a three fool pole.  Tough and likely impossible.

The opposite extreme would be a handle in which the lines attach to arms which point toward the pilot instead of away from him.  If, for instance, those arms are long enough to point the line attach points behind the axis of rotation (the wrist), any deflection from neutral will act like "reversed caster" and line tension will try increase deflection rather than return the handle to neutral.  Such a handle would, again, be essentially impossible to fly a pattern with because inputs would have to be made very, very cautiously and would tend to increase rapidly as you displace the lines; and it would take lots of muscle to get the handle back to neutral...again, if you could do it!

Taken one step further, the above conundrum is a great illustration of why you don't want to have one arm significantly longer than the other because of the effect on the amount of effort required to input and relax control deflections one direction versus the other.  Again, within the limits of "standard" handles like Brodaks or the Ted handle (or the Hot Rock on which they are all based with modest arms extended toward the airplane) the variation within the amount of overhang adjustment available will never be a deal breaker...but it compromise the best performance of which the airplane is capable.

A note on solid lines.  I have found that the VERY best way to clean them is to get a microfiber towel and soak it with Windex.  One wipe and you have two black stripes on the cloth.  A second wipe shows there is nothing left to clean!  Wet weather is still a serious issue, as is easier fatigue from inadvertant bending of the line ends.

Anyone want about 2000' of .008 solids?  Cheap!

Don't even have to put any thing on the rag.  Solids or cable I always wind up with some blck stuff when I wipe my lines down.  Was told that is the oil/grease from making the lines.  Try to  wipe down the lines at the end of a flying session, sometimes before. H^^

Wow! What a difference reduced overhang makes  ;D .  I have been using a hard points which I thought (just eyeballing them) were short overhang handles. For us old guys whose muscles aren’t what they used to be, it is probably more important than for the "young bucks" with Popeye wrists and forearms.

. . .  I just ran down and measured my offishul TED handle....1.20" (+/-/.010" or so). Truth is, mine are not (yet) glued solid, but they have never been moved from minimum overhang, and I doubt that they will be.  . . .
  . . . I can see that a lot of o'hang would be oppressive, and don't see how minimum can be a problem, but when TED speaks, I listen. PW, too. Howard, not so much... LL~ Steve

Thanks, Steve.  H^^  H^^ My mods put me naturally at 1.15 (yeah, + or – grip tape compression); a reduction ½” or so. The difference in feel is incredible y1  y1. My first flights were Saturday, with confirming flights yesterday morning. Comparing a plane with “low load” controls (and a previous handle) to another plane with “high load” control surfaces and the shortened overhang handle, the “work load” at the handle was less with the short overhang handle on the “high load” plane than the greater overhang with the “low load” surfaces. Or, as a lady I used to work with would say, "a complete 100 degree turnaround"

[using the Hunt handle] . . .  Both of us on our first flights pancaked the airplanes on the inverted pull outs of the first wingovers.  Fortunately we were flying over grass and the only significant damage was to the props.  We were able to fly again and be more cautious as we entered the new realm of Bobby Hunt handles.  After only a couple of complete flights we quickly came to the realization that the feel of these long armed handles was significantly different with much more effort required to input a pitch change and dramatically increased tendency of the system to return to neutral. . . .
 . . .
Ted

Ted's great example above describes the “feeling of too much overhang” in a way that can't be misunderstood. Got my attention, anyway. Ted's other comments contain a lot of extremely useful nuances worth reading, that I left out here to avoid repetition.

Thanks all! A very, very useful thread!

I have Ted's/Carl's handles (bought the *4* deal when I had some money! LL~ ) and the Kaz handles.  Both are extremely light.   Using oth, there is a difference.  Fortunately I have not encountered a problem with *loads* on the handle, yet, so that has never been a problem.  Hand/arm strength is not an issue. ;D  BUT!  There is a noticeable difference when I use the hard point ones.  The model is a touch more responsive. 

I might be goofy, but I can't stand a model with a LOT of line tension.  I fly with a lot less than my son does, given the chance.  Enough to have control all the time is what I have always shot for.  Some think I am crazy, but when I did get to fly a lot and practice a lot, I didn't embarrass myself too much.......

So, Ted, does line tension factor a lot into the *feel* difference in handles?

Thanks!

  And where I see it the most is in entering the square loops. With the Baron handle, a lot of times, I have trouble getting the airplane vertical before it's too high. When I flew the first "Diva", it had that - by the time I got it vertical it was at 45 degrees. We switched to a regular handle (second prototype of the Ted handle), it was a completely different thing - you hit the corner and it went in right away, and didn't have any "crank-up" time. To have replicated that with the cable handle, it would have taken some trim changes to speed up the response around neutral, which would then require it to be a lot more tail-heavy and less stable.

Hi Brett,

I think that is what I was trying to say. ;D  The model seems to turn *now* instead of in a fraction of a second later.  Make sense?
