Get the Eflite Park 370 1360 Kv outrunner : $50, and the Eflite 20-amp Brushless ESC : $42. This stuff wil hover the plane at about 1/3 throttle, amazing. I'm still waiting for a good day, it's been really windy lately, and the only good days I've been at work or to busy I'll be on vacation this weekend so it won't be then either, I'm hoping sometime next week I'll get a shot at it. I'll make sure to let you guys know though, if this thread is gone by the time I post about it I'll just make a new thread about the Yak 55 flightflex. Ohh, you'll need a stickmount for that motor with the plane, no biggie though, Eflite makes one, and it works perfectly with that motor. Go ahead and use the stock prop, it seems perfect to me, I'll let you know if anything needs to be changed once I maiden it.
