yes. BTW, after some thought, i dont think fins would work anyway because my airspeed is just about zilch. i have mixed them so i control them in pairs for aileron and elevator, all together for throttle, and linked in pairs so i can speed one pair and slow down the other causing the torque imbalance to turn the model. they are counter rotating props. i do have some control but it does not wayt to stay vertical. it just rocks back and forth until it falls out of the sky (about 1-2 cycles)
