I am going to be installing a Magnum 108A in mine that spinns a APC 16x6 9000RPM. I am not a 3D flyer but I think that should give me all the power I will need. After reading your last post I installed a set of Hanger 9 3 1/4" wheels. I did not really like the little wheels that came with the kit. I would like to have it finished by this coming Saturday to do the maiden. I think it will be close
