I tried rolling both fast and slow adding in down elevator elevator when inverted and adding in rudder to fast roll . It didn't seem to mater . Like I said the electric guy with lots of years experiance in glow too said that when I throttle up right before I try and roll the plane is going left on me as I try and roll . My first glow plane RIP was a high wing with lots of dyhedral and I could do good rolls with it and the Duraplane high wing trainer .(see photos) I would think the 4* should be easier to roll then that high wing trainer I had shouldn't it ? I looked at the wing servo and control rods this morning and I am going to move out to the last hole on the servo arm to see if that helps it was in the hole next to the furthest one out . I think like the guy at the field told me though that when I throttle up to do a roll the plane goes left and you need to stay straight when doing a roll not making a left turn . If he is right why would the 4* turn left when increasing throttle and how do I fix it ?
