If you want the perfect powerplant for this plane, look no further than the MicroDan 2510-3D! 16amps with 32oz thrust on a 11 x 4.7SF. All at a nice weight of 1.9oz. And the best part is Dan basically gives you a lifetime warranty. Even if you doink it, pay the shipping and Dan will fix it and send it back for free. Don't think too many manufacturers' will do that! My friends lasted about 500 hard 3D flights and the bearing started to wear. Sent it back and it was repaired to mint condition. Nuff said! Get one you won't be sorry!
