I'll have to disagree about the BME phone service, I've called them three times about different questions and they never failed to answer the phone and were very helpful. I have not had to use their repair service so I can't comment on it. I had the 34%extra w/BME 110 out this afternoon and I really like this engine and airplane combo. Blenders are awesome, the inverted flat spin is so flat that with a little power it will almost stop its decent. Hovers lock in easily and are almost hands off once it locks in, the hardest thing is with the 110 it still tries to climb out at 1/4 throttle. The only problem (so far) is the BME 28/10 prop seems to have little or no down line breaking and the airplane doesn't slow down very fast when landing, I really have to stretch it out or slip pretty hard to get her to slow down.
