2.4 handle
« on: December 12, 2014, 07:30:53 AM »
Mike McHenry and I are teaming up for "Team Scale" and here is Mikes handy work. Adjustable 2.4 C/L scale handle, neat and simple conversion. Lots of different ideas floating around out there, but for simplicity sake what a way to go. Low cost and easy to do.

Have subjected it to a pull test?  It must be some extremely strong plastic if it passes.

We questioned that before we started. Is 100 lbs test enough?

It looks like a nice application of KISS.  Do the batteries & stuff still fit?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Even with a 13 lb model I have never pulled anything higher than 55 lbs, but with a 5G pull the B-29 would have a 65 lb pull test, 100 lbs would be if you had a 20 lb model at 5G

I use the transmitter on the hip and use a basic stunt handle so passing the pull test is no problem

Allen,

Is the trigger the engine RPM control?

Tim, the unit is strong and the battery compartment is undisturbed.

Fred, you are right on the pull test 20 @ 5 g's = 100 lbs. I hope to never build anything that requires that kind of pull test. Just being on the safe side here.

Charlie, the trigger is the throttle control, and the nice thing here is you can set your low throttle setting and when it is time to shut the engine off push forward on the trigger and the servo travels further and shuts it off. You don't have to mess with the "trim" button. I may covert the 182 to this set up.

Blessings
Allen

With a token 5 G pull test in scale you only need to pull 60 pounds with a 12 pound model.

That's child's play compared to 25 G's in Class II Carrier:  100 pounds for a 4 pound model.
F2D - 33 pounds on a 1.4 pound model.

It takes a two-handed grip and a lot traction to hold down those big bombers.  I guess failing a pull test isn't the worst thing that can happen.

I wanted to address Paul's concern about our handle passing a pull test. As Allen commented earlier, we were concerned about the strength of the plastic. That's why we used both tensile and compression strength in the mounting of the 1/8' x 3/4" aluminum bar. Six stainless steel bolts hold the bar in place, again in tensile and compressive directions.  The lead outs are equally spaced from the center of the bar to spread the load. Allen also mentioned it would survive a 100lb pull test. Well, I was able to pull 100lb weight across the garage floor from 60ft away using 0.018 lines. The standard scale handle grunts more flying my 6lb P-39 than this handle did pulling 100lbs. So, I am hoping that Paul, and anyone else that would attend the same event as Allen and I do, would feel safe watching our plane perform. If anyone else would have a concern, I would be happy posting a video of the pulling of the 100lb weight.

     Mike and Allen,

     I'm sure you both had the same reservations about the strength of the handle and am also certain that you built this handle and tested it to clear any thoughts about it working OK for the planes that it will be used with. That's what we all do when we start any new project. It is also why we have the pull test at the contests. I don't think you should waste your time jumping through any hoops for the nay Sayers, go to the contest, pull your plane and go flying.  Eric

At the 2014 Nats some contestants were allowed to disconnect the metal cross bar and test it without the plastic part.  This obviously invalidated the pull test, but they did it. 

I have a couple of those car controllers.  I don't care to break them to prove a point.   In the spirit of open discussion, I wouldn't fly a valuable or high-pull model without steel or hardwood throughout the entire stress path.

Of course nobody protested the pull test procedure, did they?   Now if they are holding the part that is pull tested it is a different story.  I remember the hub bub when the contestants were told the safety thong needed to be pull tested also.

As I have stated elsewhere I prefer a slide pot instead of a trigger.  I prefer to be able to set and forget the throttle.  For scale I fly, most of the time, at 1/2 to 3/4 throttle.  To hold a trigger at less then full throttle could be tricky.  I repackaged a 2.4 car radio to a standard Tom Morris handle.   It did require some knowledge of electronics and good soldering skills.  But as a standard handle, pull testing is not an issue and I prefer the slide pot throttle.

Thought I'd light the fuse on this great Thread again.

I'm still thinking about the ideal scale 2.4 handle. For my use it would be three channels, throttle, flaps and retracts.

Thread is a tad old, so I'm guessing there has been some improvements in equipment.

Hoping for updated photos of great handles.

Doesn't really have to be 2.4 does it?

Could you enter a contest with some other old channel?

I have this fun scale project in the works that will need a method to control the engine.

2.4 is a bit costly.

Bill Bischoff from the carrier circles had a solution that repackaged the guts of the 2.4 Ghz car unit around the strong metal handle. I fly with the separate transmitter, the advantage there is that I can have one transmitter and each airplane has a receiver. Then each airplane has it's own set of dedicated lines that are the correct diameter, length and are adjusted for neutral elevator once and never have to set every time I fly. Since I make my own handles having a set of lines for each model is not a problem. Then take advantage of the model memory for all of the servo settings such as end point and servo reversing.

As for cost there are lots of cheap and expensive units. I fly with the Tactic 2.4 Ghz systems that work great are not too expensive compared to Futaba and other brands. Hobby King will have the lowest prices.

The transmitter hangs on my hip with a clip on my belt. Either way you go they all work, pick the method that works for you.

Mark,

Yes, I should dig them up. Good advice coming from a scale judge. Thanks.

Fred,

You still have to have a receiver for every model, unless you remove and replace it?

Possibly the TX on the hip isn't all that bad an idea.

I just remembered, I have flying lines on the wings to fuse and to the wheel spats to deal with. About 14 of them. YIKES!

the problem i see  with most of these handles is that u need to drag the lines back to the plane to work the throttle for starting
Dave platts handle has a removable 2.4 unit that can be taken to the plane for starting and then attached to the handle for flying

in 2014 the hard working officials were assuming that all participants knew the rules and would police themselves .

Yes Dave's handle was pulled without the main unit attached , the volunteer pull tester had not been briefed on what to look for , and no one checked for wrist straps .

i spoke at length with Mr Brodake and the other scale officials at the Brodake fly-in about these problems  Although i didn't make the nats this year i heard that these things  were covered much better in 2015.

  on a brighter not, i like to use a 2.4 car transmitter in my left hand .i can take it to the plane and being originally left handed ,i have no problem using the throttle trigger in my left hand which leaves my right hand free to just fly the plane

i did fly an ARF nobler the other day with a home made transmitter box small enough to fit in your hand with a slide knob for the throttle and it made keeping the speed consistent very easy ,it could be set up for 8 channels MMM re tracks flaps, rudder ,smoke.

Charles,

If you fly in an AMA sanctioned control line contest in an event that allows an RF system for secondary controls, it MUST be with a 2.4 GHz system.  As has been suggested by others, take the time and read the rulebook.  It is on the AMA website.

I have multiple CL scale models and since the Tactic recievers are cheap enough I can put a receiver in each plane and not have to move the receiver from plane to plane. Some other brands are more expensive, something to look out for.

When I fly the models I roll the lines out just like you would for a stunt model and the handle never leaves the center of the circle. Then because I have a separate transmitter I have it with me when I start the motor, walk back to the handle and then fly.

You will take advantage of the model memory with the transmitter, this is where the transmitter remembers all of the servo settings for each airplane such as servo reversing and end point. Not many of the RC car 2.4 Ghz have that feature, but it is more common on the airplane transmitters.

Flying the model with the right hand and operating the other features with the left hand is not difficult once you get use to it. Everything is done by feel.

The Guys you fly with the 2.4 Ghz handle are dragging their lines to bring the handle to the model, then walk I back again to the center.

Fred,

Sounds like clear thinking having the TX by your side.

I'll look into that TX.

I'll have to read the rules also.

My interest would be fun scale and just this one local meet. I think they make their own rules up at this meet?

I've vacuumed the dust off the Gee Bee Z.  ;D

I thought possibly this Thread, or my new reply, was missed. Scale doesn't have the high participation numbers.

I really need a good handle. One that isn't just a car handle converted to CL. They look to top heavy.

Also this bit about bringing the handle to the model then walking it back to the center is something I wouldn't have interest in.

The plug in plug out, as mentioned, seems like the way to go.

I really don't have the time to get this done by myself, not to mention the loss of money in development.

However, I'll be glad to work with someone on this.

There have been so many 2.4 handles over the years, at the Nats this year I walked the row of handles and there was every possible combination. One Bill Young handle one of the most compact handles made with 3 channels and a nice trigger. The converted RC car handle are clumsy in my mind but then I like a stunt handle that is very light and small with nothing attached.

There is no perfect handle, in the end you have to decide what you like best. Just so you know you do not have a trigger on the handle to fly with throttle, it all can be done by feel with the electronics on the hip.

I'm not a C/L Scale flyer, but thought of building a Fun Scale or Sport Scale project for Brodaks in June. Probably will ,but let me play Devil's Advocate for a moment......and I know the rules are the rules,but don't you think that allowing R/C to control the functions on a C/L model defeats the spirit and intent of "Control Line" scale?  I'm not trying to get juices flowing, just good conversation between modelers......Fraternally,PhillySkip

You are correctomundo, sir.

There are huge point bonuses for things that used to be engineering challenges.  The winner of Fun Scale at the NASA Scale Challenge used an RC-ARF electric with retracts, flaps, a carrier hook and motor control, all of which were purchased off the shelf ready-to-fly.  The model was perfect scale, including rivets and markings, all factory molded. The contestant's only action was installing a bellcrank to work the flipper.

The spirit and intent of modeling was not only defeated, but mocked.

Paul,

You cannot blame the modeler. Blame is on the individuals that write the rules.

Simply have categories, no rocket science there.

Especially for the individual that competes with an ARF.

Have an ARF category. DA!

 Paul,I didn't know that they allowed ARF scale type models to compete in Scale competition. That's just so wrong on many levels.....It's a violation of sorts.....

Charles you're right, if they do allow ARFs put them all in one class.

Fun scale only has 5 points for outline, 5 points for color and markings. Then 100 points for flying, basically the static points vary from maybe 6 to 10 points so the "Static" score really does not make a big difference. ARF's are only allowed in Fun scale. It also allows models that you have purchased to be flown in fun scale since you are not the builder of the model. So if you inherit or pick up someone else's model you can fly it in Fun scale.

The contest is won or lost based upon the flying score in CL Fun scale.

In RC fun scale they give 5 points if the outline of the model is correct or even close, everyone basically gets 5 points and then it's all flying. The markings and colors don't even have to be correct! So we still have some points to make sure the markings are correct in CL scale.

First, I want to say that I am a strong advocate for the Precision Scale events.  I feel that these events should remain as a basic core of the rulebook for all Control Line events.  We have a handful of people to thank who stepped up several years ago to reestablish the CL Precision Scale event in the AMA rulebook after the then Scale Contest Board (made up of RC people) allowed the CL Precision Scale event to be removed from the rulebook.  Thankfully, we now have a CL Scale Contest Board.

It is my understanding that the control line "Fun Scale" event was established to provide an introduction to CL scale competition for those who might not be inclined to even get started participating in any kind of CL scale contest.  Thus, ARF's, RTF's and non-BOM's are allowed to compete.  (I think this evolved several years ago from the fact that RC has or had a similar event to promote interest in scale competition.)  The fact that CL Fun Scale contests are held and people choose to enter cannot be a held as a bad thing for scale.  The purists from their lofty towers can certainly look down on the Fun Scale event, but people are certainly not being forced to enter such events.  The introduction of the Fun Scale event cannot be held as a cause for lost interest in CL scale.  On the contrary, entries in CL Scale contests seems to be increasing, at least as witnessed in recent years at the Nats.  Few other CL categories (excluding CLPA) can make the same claim.

The BOM rule still applies to all of the remaining CL scale events, though CL Team Scale allows the pilot to be other than the builder and at least one 1/2A scale contest allows proxy pilots.

Yes, Fun Scale is an abomination to the purest minded competition scale builder.  Much in the same way as what the oxymoron called Profile Scale is and its unofficial event derivatives called 1/2A Multi-Engine Profile Scale in which I have actively participated in for the past 10 years or more.  But CL Fun Scale continues to have participants and interest does not seem to be abated.

Fun Scale eliminated the BOM, maybe with the intent of letting builders sell, give away, or loan out models.

It quickly devolved to buying an RC ARF and installing a bellcrank.  A 3-D model with correct markings gets a certain 10 points.  A genuine model airplane can rarely achieve perfect marks.  The writer of the previous remark knows full-well that in Fun Scale the scores are always very close to a full 110 points.   So losing 1 or 2 static points is fatal.

The use of level flight, gear, flaps, carrier hook and electric motor control yields a sure 60 for flight score.  So the only points in question are a total of 40 for takeoff, landing, realism and one option.  Maybe high flight or taxi lap.

Sure, the person who won with the ARF Dauntless was within the rules.  He can to win EVERY fun scale contest until they change the rule or quit buying prizes for an event with 1, 2, or 3 entries.

 Perfectly scale to what?   As no documents were required, it is pretty irrelevant as to how perfect it was.    It seems scale is doing it pretty good right now.  Lots of entries in CL and RC.  If you want to enter expert sportsman or FAI you still can, but the other people can get their feet wet with an ARF if they wish.  Gotta get them to start somewhere.

You can buy this and get the full 10 points.  
Why would a builder enter Fun Scale?

So four guys buy & fly. 
What's left? 
Takeoff, landing and high flight.

 A builder would not enter fun scale.  Unless they just wanted to have fun!  And participate in flying in a competition setting.  When I participated at the Nats in 2014, there were many pilots that entered in several classes.  From fun scale to expert sportsman.  I did not realize there were that many classes as I was only focused on expert sportsman.  I do not see anything wrong with having a scale flying class, and a class that get a full static judge and flying.  I cannot see why having these different classes hurts the scale participation.

What I find interesting if you compare RC and CL scale entries at the nats this what I have noticed..

In RC scale people tend to enter one event and RC fun scale is very popular with 21 entries in 2014, Expert Sport scale only had 10 entries. they had 38 pilots with 49 entries in the competition. on average each RC pilot brought 1.3 airplanes compared to the average for CL scale was 2.1 per pilot. RC fun scale only requires them to prove outline that I usually done on Saturday morning. the colors and markings can be anything and that feature is never judged. Typically everyone ends up with the same 5 points for outline in RC scale.
 
In CL scale people tend to enter multiple events, so there are fewer pilots but in some cases we had 21 pilots with 45 entries meaning that on average everyone brought 2 airplanes. that year at the nats we had 10 sport scale entries and 9 fun scale entries. In CL fun scale they actually judge the models on Friday and the scores range from the 5 or 6 points all the way up to 10 points for both outline and colors and markings.

I take my older models some of which are ARF's that have some details added and fly them in Fun scale. I also fly a 2nd event so that if one airplane gives me problems I still have another airplane flying at the contest. With that much spent (time, energy and money) to get there and effort I would rather bring 2 or more models.

This year we won't get to see the RC scale guys at the static portion since they are running on a different weekend in June

I am no longer competing in scale so I don't have a dog in this fight but when I did compete I did fly some fun scale.  It ain't as easy as it sounds.  A converted RC ARF may or may not fly worth a hoot as an U-control.  I had one that no matter how hard you tried it would bounce on landing.  RC ARFs tend to be heavy and are a hand full to achieve real aircraft looking flight.  Having said that fun scale has several advantages.  First of all it gives you serious scale guys a second (or third) event to enjoy.   The cost of travel and motel is high and another event is fun.  Secondly fun scale doesn't compete agents classes that have builder of the model rule.  So what's the beef.  It not as if your hours of hard work to build a model will be thwarted  by some ARF.  And their is still the fact that fun scale may well bring in new blood to the sport.  I don't see any bad things for the sport in fun scale.  Besides if you check, most of the fun scale airplanes are being flown by the master builders because it gives then a second event to enjoy.  It's just like Old Time Stunt.  Most pilots are master fliers that are looking for another event to have more fun.   S?P

Getting back into C/L after a 20 year layoff, I REALLY like the idea of a radio handle.  Why not take your standard handle, add a couple of standoffs with a plate and velcro your car tx to the side? Seems like a simple inexpensive no-brainer. Just looked at a 4 channel unit for $99. Sure beats the multiple bellcranks, extra lines and microswitch contraptions used in the past.

I 'spose they had the same type convos when Roberts mfg'd his 3 line setup.

Mike:

What you describe is exactly what I have done and competed with for several years. The only thing with mine is that I used a Radio Shack project box and filled it with Clancy Arnold's U-Tronics system. The neat part about it is that you are using your original handle which will positively pass the pull test and both units are up in front of when you are flying.Others have hung the radio unit on their belt. or other places, which places the radio unit out of your sight while you are concentrating on the airplane.

Jim,

Sounds like you have it under control as far as the setup you are using. I for one would like to see photos of your efforts and success.

If you already Posted photos, I apologize for not remembering or seeing them.

I do have to decide on my direction for a handle soon. Decisions I have to make.

Thanks in advance.

There are two very different systems, I use a RC transmitter that hangs on a clip on my belt. I operate that with my left hand while I fly with the Right. I like the handle to be as small and as light as possible. I also use the same transmitter for all of the models (using model memory) and each model has a dedicated set of lines. I attach the lines, make sure I pick up handle the right way never have to adjust neutral at the flying site.

A friend is trying a concept where you move a toggle switch and linked to a transmitter on the hip. basically imagine a toggle switch on a stunt handle and that has two wires that goes down to a transmitter on the hip. You never touch the transmitter the switches attached to the stunt handle are for each channel.

The RC car transmitter can be big and clumsy in my mind

all of the systems work you just need to find what you like best!

Sounds like a good plan Fred. I'd prefer not to have any knobs/switches on the handle. Too much chance of bumping something while thonging up. Gotta read up on 2.4, the old Orbit ain't gonna cut it ;D

The other reason why I like the throttle and other switches on the separate transmitter is that I found when I flew with a handle that had toggle switches and a trigger for the throttle I would not get a steady flight. I would accidently bump the handle causing a bumpy flight.

every time I reached up with my left hand to move a toggle switch the airplane would ever so slightly be affected because it messed with the handle which controlled the elevator. Then if you fly large airplanes you want a get a good grip and if your index finger is operating the trigger then you only get a partial grip on the handle with 3 fingers instead of the 4. The 14 lb B-29 pulls about 40 lbs so you have a hang on tight.
