This model looks like a candidate for the Cyclon Mini Punch. 2.8oz brushless outrunner/geared. Swings up to a 14 x 9 prop at about 450watts. That should overcome any weight issues. Costs more than the airframe, but most quality powerplants do. Small price to pay for having more than enough 3D H.P. under the cowl. Performance should be phenominal! Can't wait to try it out. Like the color scheme too.
