uranker i upgraded from phoenix 4 to 5, i downloaded with no problems. it is free. BUT, after i loaded it i had all kinds of problems . i never could get my models to work like they should. i finely erased all the software that was phoenix from my computer and reinstalled the 4 version that i was using, by the way, i never had problems with the 4 version. now that i am back to the 4 i cant get the rudder to work like it should when i move it to the right it is smooth like it should be, when i move to the left it takes of like a rocket, to fast to fly with. i've tried every thing phoenix reccomends in thier software and on my transmitter, and i can not get it working like it should. all the other controls works like they should. i'am thinking about downloading upgrade 5 and trying that again. all suggestions on how to correct this would be appreciated. ii am using fly sky th9x transmitter
