Turned it around ROFL... Heh, I did that once out of desperation, only to realise my mistake

I take it you have replaced the Servo's - probably with HS-55 or something similar. HS-55 are a bad choice BTW on a W4, but that's another thing.

The top four dipswitches on the back of the W4 transmitter change the servo direction... It will be 1 & 2 that control cyclic.

Just flip the correct one. If you push the stick to one corner before you flip them, and have the W4 on (unplug the rotors first) then you can see which one is changing direction. Makes it easy. (Flipping the throttle switch by Mistake - Number 3 I think, makes it go full throttle - be carefull ! )
