The Saito FA-150B will happily swing an APC 16 x 8 at 10,000 rpm, offering oodles of thrust and torque for power hungry 1/4 scale models. The case dimensions are the same as the Saito FA-120S, but with more than 20% extra displacement to play with, the Saito FA-150B should satisfy even the most demanding of model pilots.
