I bought one used from the LHS and I'm not sure if it was built right. When I do a roll if I don't pull the nose up to about a 35-45 degree by the time it completes the roll it is pointed to the ground. I have the ailerons at the max deflection and my radio is set as high as it will go and it still does it. I have one club member who says that that is normal and another says it should roll like it was on rails. I am flyng a OS 91 4 stroke with a 13-8 prop. So who is right?
