I've seen the EVO-102 flying, and it's almost as strong as the old 3W-100 - down about 200 rpm. The BME advantage is light weight. Not everyone can take advantage of a light engine - depends on the ARF and kit design. The DA-100 is at least as strong as the old 3W-100 and is generally better running in the low throttle range. The monster power motor is the 3W-106. My buddy Walt had his QS out last weekend. It is 300 rpm stronger than a DA-100 on a 27x10 Menz-S (6700 rpm). If the BME Extreme can generate this kind of power and knock off 1.5lb, then they'll have an awesome motor. I hope they do, because that will force DA, 3W, and ZDZ to make their motors even better.
