3600KV or 4700KV? I'm just wondering since Tower's website recommends an Air Power 3600KV brushless motor from Golden Horizons for the MQ (20A max, 7-15A continuous, 6,600KV [mistake?]. The 4700KV motor is listed at 25A with continuous current of 18A. Either way, I haven't tried either motor though I did notice that Tower's website mentions "cogging" even when the speed control is set for a low power start and low timing.
