dacaur.. seen your video in another post. it shows you have expierence . made me want to speed up the learning curve a little/did some piros both directions and i almost have it trimmed well enough to hover hands off safley for a very short amount of time. my trims were almost fully to the left on rudder and aileron and im still working on fine tuning. yours seems more stable than mine on its first flights judging by the hands off hover. the battery state of discharge does seem to effect mine quite bit as far as trims go.. about mid pack it flys its best. good point you made on the rudder expo/not sure if it turns like that do to dual motors or radio set up but mine seems to have little authority then as i increase rudder slowly past 3quarter then its like a turbo kicks in and really spins quick. i'll have an updated video of my progression today. thanks for the video
