Rolling lord mounts is the way i had to change angle on my slingshot and did so
partially by rolling the rears over and adding shims. Took most of the heavy
stick away. Original slingshot had 3 degrees too much pitch in airframe on motor
mounts as it only has 9 degrees angle of attack on wing vs 12 as the rest
