you will get hits on the feather if you are not careful. the best lightest ones I have are the 555, electron 6, slimline 8, an old 535, and an expert 6 channel (jr clone from horizon). they all work well. the expert is great, got it on hitec shift in my 72 powered ultimate. been in several planes, NEVER a glitch, very small. but the hitecs are no slouch, and service from hitec is excellent.
