ok so im not new to this but i lost the manual for my cx-2 and cant remember what the gain and proportional trims do. can someone explain to me what the functions of these are so i can get my heli to stop doing constant left turns? thanks guys, chris

gain is to prevent tail from wagging...proportional is to adjust yaw tendencies...ie if tx has all trim set to middle[except throttle] and heli yaws left
adjust proportional buy turning to right to 'counter' the left yaw tendency do opposite if yaws to right.

reconnect battery each time you adjust otherwise setting change will not take effect.

thanks a ton! im getting it ready to sell cause im upgrading to the soon to be released blade cp-plus. had to re-solder new power wires into the rx cause the other ones were a bit crusty for some reason. its flying nmow but i gotta get it trimmed. so thanks again bro,chris

np Chris..
so your moving up..

did you hear about the new Blade 400 a bit bigger than the cp plus though and much more $
but it comes with DX6i spektrum radios...
