Serendipity strikes
« on: December 28, 2012, 03:12:29 PM »
Powerful thing, search engines.  I bought into the EF-1 pylon koolaid over a couple years ago to do a little semi-scale Formula One racing.  Bought the plane, motor, three 4S battery packs and TP 820 charger.  All great, but the racing in this area has been minimal, so mostly the model collects dust.

But thanks to the fore mentioned search engine I found that a 4S 2700 pack does have a use other than paper weight.  When teamed up with a Power 15 and the right prop it can act like a .35 stunt engine.  On top of that, I have a H9 PT-19 that I picked up in a moment of profound weakness (it's a long boring drive from Phoenix).  Searched that term too, so I found a couple old threads on converting that with the Power 15.  So that is to be my first E-CL project.

I had been debating building a VK Cherokee Babe to electric with either a Power 10, or Power 15 for a winter project.  So at least the motor has been decided.

So a CC Phoenix ICE lite 50 to twist electrons (holes actually), and some type of controller (TBD) and a handful of test props and I can fly again like it's 1969 all over again.

Robert,

More power to you (pun intended)!!!

I recommend a Will Hubin timer to go with your ICE 50 ESC. His FM 9 system (programmer and timers) is great if you are serious about having several E powered models. Otherwise, he can fix you up with a suitable timer for under $20.

Email him at whubin@kent.edu

Thanks John for the timer suggestion.  The timer is the great mystery of setting a system up.  I've also just considered using a Spectrum receiver, then I would have a throttle so I could abort early.  It might also help program a controller since the power would be logged by the ESC.  But that might cause the ground to open below my feet and swallow me whole for building a hybrid.

The thread I read on this set-up were several years old.  I wonder what their final assessment was in terms of hardware and props?

Robert, if you're picking it up again after a layoff, you may want to get a 2.4GHz car radio -- you can hold that in your off hand while you fly with your usual hand.

Then get a timer if you want to get serious about competition.

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

Ah, pistol grip speed control.  That makes more sense than a DX-8.  It's been 38 or 39 years since I stuffed my last Magician .35 while trying to fly it without looking, dashing any hopes of ever flying combat.

Please tell your next of kin to post something here if that happens.  Others of us secretly intend to do the same thing, but you point out a concern.

Hmmm an interesting point!  Since our planes are tethered, they are officially a "ground vehicle", so a car radio is actually the legal way to go, while an airborne unit isn't.  Comments, rules guys?
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

With 2.4GHz it doesn't matter.

With 72/75MHz -- yes, I believe that you'd need a car radio.

The intent of the FCC rules surrounding 72MHz was that separating surface and air operation would prevent shoot-downs by car guys checking for on-air activity, turning on, and catching some plane that has line of sight to his transmitter as well as yours.  Given that the CL plane never gets more than 70 feet up, I think it'd count as "surface".

Well I doubt that getting dizzy will be the problem.  I flew Formula One pylon for over a decade, Q40 for another 5 years and still do some quickie racing from time to time.  Six second lap times with the faster stuff, but a half turn of the pilot's rotation only takes about 0.9 seconds.  In pylon racing you get to look at the top of your airplane from a distance of 75 feet for the second usually while dodging bad air from other airplanes.  I always thought that my earlier years of ukie helped me turn pylon 2 and 3.  The hard part of pylon is adjusting to the fact that elevator controls direction and aileron controls altitude.

I went to the Nats to compete in pylon back in the 80's before Muncie turned it into a week long local contest, a format that I completely detest.  I was blown away at my first Nats at Olathe Ks. in 1968 by the Navy hanger full of models, control line speed, combat, stunt, RC Pylon, RC scale (Dave Platt's SBD), and of course free fright.

During part of the 70's when I was in college, I worked part time at Progress Manufacturing for Chris and Ethel Machin.  I'm sure that some of you still hoard a few Rev-Up's.  Few things get the blood pumping faster than to be sitting a a shaper table while a 3 inch diameter head turning 20,000 rpm finds a hidden flaw in a foot long block of hard maple and throws half of it into a 3/4" panel of particle plywood.

As simple controllers go I think the e-flight timer is about as easy as it gets.

Well...........I feel bad about that idea now, since I just returned from Florida where it happened two weeks ago, and again in Illinois last week.

Hello Robert,
Welcome to the fold ... and I sure do get the bit about the knot in the fly-cutter. Yike!
Those of us with a foot firmly planted in both CL and RC have to be highly dizzy-resistant!
Let us know of your progress,

Robert, as a fellow Pylon player,, I share the joy,, I actually am lucky en0ough to have a group of guys up here who have seen the light, put the Q40 and 428 stuff on the back burner, we fly APRA 9 Thundertiger 40 quickie or 424) and EF-1,, the last few races we have had right at 20 pilots in each class,, pretty awesome,, I also fly CL ,, electric,,

now about that EF-1 you have just sitting there collecting dust,, I have a couple slightly spare CL kits I may trade you out of that thing ;)
For years the rat race had me going around in circles, Now I do it for fun!

Mark,
I used to race quite a bit of F1 with the PROPS in the 80's and early 90's.  From Toledo to Whidbey Island and as far over at Spokane.  I raced with Strom, Bergstrom, Huber, Rice, Kelly, Watson, Mcindoe, Cady, Mikko and so many more names that I have forgotten.  It was only 800 to 1000 miles up from the bay area in California.  Of course most of them came down to the SLO race in May which was almost as big as the Nats back then (and a lot faster).

Thank you Dean,

While it seems like most RC pilots have little use for their issues of Model Aviation, I always liked reading about what other areas of the hobby were up to.  Competition in any venue improves the breed, and it seems like the people at the top of any event work at it very hard.  They also tend to share their concepts and ideas freely, to ignore them would only decrease the tools available.

for what its worth,, Stroms , at least Senior, is now flying control line PA as well,, then Marc Winz started last year ( he started pylon about when I did,, we have some good races) another name from that era is Pat Johnston, he did F1 as well,, he is now a fixture in the NW stunt scene,,,

I am working up a design for a thunderchicken, for EF-1,, Love the class, the planes look so cool,, just wish they were about 20 mph faster,, to match 424 speeds,,
