The fundango is actually a nice airplane in search of a good powerplant. I had one I experimented with for quite a while. Ditch the idea of flying it on the sp400 with gearbox as they suggest. The best combo I used was a speed 300, geared 5 to 1, with an 8X6 APC "E" prop, on 8 cells. 9X6 works also, but the current was a bit high for my tastes
