I have the perfect set up for you, I have the yak 55 and the set up I reccomend, and beleive me, it totally rocks. I have an Eflite park 370 outrunner @1360 Kv, with a 20a speed controler, the motor will pull between 8 and 15 amps depending. With that setup using the stock prop that comes with it you can hover right around 1/3 throttle, and at full it can put an estes rocket to shame! I would say you may want a higher discharge battery, I have a thunder power 3s 1320 mah with 13C continuos ans 20c burst. That puts out more than enough for that setup. I have a JR NES-241 for rudder control, had it spare from an old plane, and the rest are Eflite s75s, they're like $13 bucks and do the job real well, the've got more than enough torque for the plane. I paid under $100 for the motor and speedo, about $50 for my battery, and like I said, $13 a piece for servos, not a bad deal considering the rediculous performance of this thing. I think that it'll be just what your looking for, perhaps more lol. Good luck, and I hope you enjoy it when it's done!
