RE: I need help
There you are !
MinnFlyer nailed it. The key here is to use expo correctly and not over do it and have poor control around neutral. The - or + depends on brand. I like -20 (futaba) on an everyday sport model such as a four star and up to -35 or -40 on my Pro Twister.
The first time I had a radio with expo I was flying a Sig 4* 60 and thought it was like cheating because flying smoothly was suddenly easy[8D] IT is fun to play with so enjoy!
