I find this sight tremendously informative on matters of the Super Cub and have been visiting for a while. Recently bought a used 3419 super cub. The antenna wire on this one seems shorter than other pics I've seen of the cub.(only barely reaches outside of the rear of canopy). Will this be a problem for transmitter distance for this channel 3? If so how would I remedy this other than buying a new receiver esc? Am planning to convert to Lipo and will prop down to either 10x6 or 9x6. Thanks

Welcome to the club If your good at soldering open up the rx and solder a new antenna wire in. If not try to splice some wire onto whats there good luck, a shorter antenna will shorting the range

Have no problem with soldering. Have done lots working with electronics. I presume the type of wire used as antenna isn't critical. Seems to me this plane must have had antenna shortened for some reason before I acquired it.(probably a crash of some sort). Anyone know what length antenna the super cub comes with? Won't be flying the cub for 2 or 3 months yet as we are in the middle of winter here in mid-western Canada. Thanks for info.

Thanks for the info on length. Just occurred to me maybe someone has a receiver that has died and would be willing to part with it antenna wire and all. Let me know if so. Thanks again

Suggest you charge stuff up and try it out before you assume it is all OK. A short antenna is fine for bench testing. That could save you some grief when the weather warms up.
Type of wire does not matter much, length does. I measured 2 of my old 27MHz. One is 34" the other is 44" but it is obviously sliced and I bought it as a 2nd hand plane. Both worked fine to the limits of my willingness to fly them for distance.

Have already charged the NMH battery a couple of times and all electronics works. The plane had sat around about 5 years without much use and the Nmh battery had about 7 minutes of run time on the motor after charging. Haven't checked receiver from any distance as yet. I have now switched to Lipo battery and removed jumper. Had to do the wing saddle mod as back had been crushed opening up a 1/4' gap. The antenna wire currently is 12" at most so I will change that. If the receiver doesn't work satisfactorily I'll change to 2.4 gig and change servos as well. Have all of that on order already. Switching to bigger wheels as well since our air strip here is grass. Waiting for warm weather. Thanks for your help.

Hello all.
I am a newbie as well although I have been on the forum for months reading and reading. I recently picked up my SC from the LHS and the antenna wire only reaches from the esc to the rear of the cockpit. Why would they come from the factory that short if the plane will not fly correctly with that short antenna? The new models are 2400 MHz. Is that the difference in antenna length from the older 27MHz versus the new 2400 MHz?
I really enjoy the forum and only wish I had much more tiem to read it.
Thanks, Ron

Antenna length is a function of the frequency. 2.4GHz is VERY SHORT so has a short antenna-that is normal.
You can read before you make your mistakes, or after you make your mistakes.
Guess how most people do it?

This Super Cub is fun to fly and durable to. Went out to our local site Friday in winds up to 29Km/hr and better and flew about 35 minutes and then packed it in as the risks were getting to great for someone who has been into this for as little as me. Was all by myself as well. Helped me get over the idea that I coudn't do it and it was kind of exhilerating to. It will be easier now to get out there in less than perfect conditions as that only happens a couple of times every summer in the flat prairie of Canada where I live.

If you are flying in that kind of wind (18mph to us yanks) you are doing very well indeed. If you have any hills in reasonable distance you might want to think about sloping-it's almost like a different sport.
