Build a 'stick/tissue' model for electric power

Anyone out there with experience in these things:

I've had a COMET Piper Cub Cruiser model kit sitting around for quite a while, waiting for someone (originally my son, but looks like it'll be me) to build it. The box lists it as 'suitable for 1/4A to 1/2A gas power or rubber'. Reading my past issues of 'Model Aviation' from AMA, I hear lots of gripes about how tricky it is to 'convert' specs for gas to electric.

Anyone with experience interested in helping me out with this? In return for your help, I'll send you pictures of stage by stage construction and final flight. I envision modifying the kit to 1) house the usual electric rc stuff, 2) add ailerons and work them with one servo instead of two 3) control rudder/elevator with pull/pull rods/cable, 4) run it from my Hitec Laser-4 radio.

Not too tough to do. Typically, we'd suggest rudder and elevator only to keep the weight down, but ailerons would be fine, it'll just fly faster. The poor centering of most of the affrodable sub 6g servos means you'll end up with 6-8g servos, picos or HS-50s. The reliability of the Berg Microstamp4 DSP receiver means that's the one to use. A small brushless outrunner like a park 370, Hyperion ZZ2205, or Axi 2208 would be a good place to start with a 1/2a cub. For those motors, Lipoly packs in the 700-900mah range make sense.

It would be nice to know the wingspan, I'm guessing it's around 34-38" or so. If you need more tech assistance, contact us at

Good luck!

Would be glad to help you, but I would need to see (1) the plans from the kit (2) what electric stuff you plan to use (3) what servos you have with your HiTec laser-4 radio.
I suggest we communicate via email to avoid clutter up of this post.

I've built one of these ages ago for the Mattel Galloping Ghost single channel radio and a Cox .049 Babe Bee. I could never get it airborne long enough to know if it would have worked.

The Comet kit is OK, the wood is somewhat heavy but it should fly fine with a GWS 300 EPS drive or even one of the Balsa Products cheapy brushlesses, HS55 or Pico servos, and a decent RX like the Hitec electron or Berg by Castle Creations.

Like someone else mentioned, I wouldn't get to hung up on ailerons, as this kit was a freeflight, it didn't have true scale size tail surfaces and was set up with dihedral. If this is your first rubber kit conversion keep it simple with just RET, only 2 servos and it will be fun to fly none the less.

Pat Trittle designs his airplanes in the stick and tissue tradition and they do just fine. There are changes that need to be made to pure rubber kits but they are not too difficult. Think each step through before you reach for the glue bottle. Use the lightest material that will do the job. Keep in mind the fact that electrics suffer far less from vibration--dont over build.
And most important---take your time. Dont rush the build. If your not sure get help.
