+1 on that ...... I have actually used, and will continue to use an AR6200 in both my .50 sized nitro heli, and my .60 sized nitro plane as it IS a full range receiver, and they have both performed perfectly - just ensure that both receivers signal lights are not flashing when you power it up, and that way you'll know you have a good solid and usable signal between both TX & RX. If your worried re vibration from a bigger motor, just insulate it with some medium density foam that is designed for situations where vibration needs reducing (both of my models are set up that way).

It is indeed a 'full range' receiver, and is perfectly happy in nitro aircraft. Just run it on at least a 6volt battery pack (5 cell nimh 'AA's for example) or regulated 7.2 volt + lipo (etc) system, as Specktrum receivers can get temperamental and brown out if on a 4.8volt pack, and it voltage get's too low in it's available charge.
