Mr_Matt,
I actually seen a BMT-80 at Winimac this year. The guy was flying it in a white Roo with yellow or orange accents I believe. The motor looked like any other KJ66 design other that the tail cone was not open in the middle where it meats, like the Ram 750 is, if that makes sense.

I asked the owner about it and he seemed very happy with the motor and he did not seem to have any problems with it. I believe that the BMT start box also charges his on board batteries when it is hooked up to the ECU, not sure if it charges the turbine pack or the RX pack but it seemed like a nice idea.

Now back to your regularly scheduled discussion,
Randy
