Hey guys

I just got my 7CAP this week and i set it all up and went to fly today..
i got out at about 5:45 this morning so i wouldnt have to deal with the wind
anyways i set up dual rates on ailerons...elevator and the rudder..
a little but of expo so i would screw things up too bad

ok so i set it up just fine..and let me tell you this was the first time i did it and i feel like im a pro at it..
anyways

I was trying to do a knife edge and i realized something was wrong.
everytime i used my rudder my plane would not only turn but rotate as well..
i couldnt correct this with ailerons or anything
anyone ever have this happen to them or what else should i mix in ??

Thanks..
Felix
