I prefer PCM in helis because of the programmable fail safe. The likelihood of glitching or problems with a heli is higher IMO and I'd like to know that if something goes wrong my heli is not gonna fly off and hit something, but rather it will just stop and fall out of the sky right where it is. PCM also helps to reduce glitching and on an electric heli this is paramount IMO.

Get the 6102 then you will be pleased with it. The 610UL Rx it comes with is a great little FM Rx. I have 2 of them on 3D planks and have never had a problem.
