Just finished my first build. I build the simple cub. I attempted its first flight this weekend and it went as expected, right into the ground. No worries as I am learning all this stuff. However, I did notice that every time it crashed it flew down and to the left. That got me thinking of thrust angle. My UMX timber has a very visible tilt of the motor to the right. I did not see any thrust angle on the simple cub. Should I be adding this in by shimming the motor? If so, does it need to tilt tot he right( when looked at from behind) SHould I tilt it up as well?
