Anyone tried the MPJet 25/35-20 on the 3DX yet? Seems an incredible deal at $50 for the motor, which includes a 4:1 gearbox. $125 with a Phoenix25 ESC from http://www.mountainmodels.com The hobby lobby website http://www.hobby-lobby.com/brushless_mpjet.htm claims 26oz of thrust with 8 cells and a 10x6. Seems a good fit for teh 3DX, no?
