Tim,

I can tell you that my setup on a Kontronik Fun 400-36 with 10cell 1950FAUP peaked at just over 400W then settled in at 385W and 32-34 amps. It's not quite as fast as the Mega 2T, but flies very well and I have the option of adding another cell or two, thus getting it near the 500W range, where the Mega is pretty much maxxed out at 10 cells or a 3S config. So, in reality, yes the Kontronik will produce some serious power, but the added weight to get it there wouldn't be worth it. The motor alone is almost twice as heavy as the Mega...good for handling power dissipation but bad for weight. My model weighed in at 29oz WITH motor, fan ESC, Rcvr and two HS81 MG servos and no battery...so it's pretty light.

The best combo to date I have seen fly though is still the Mega 16/15 2T on either a 3S2P 2200mah or higher Lipo pack or a 10cell 1950FAUP...they both fly about the same speed...draw is around 40amps or so and around 450W. You could go 3T, but that has been a bit dissapointing in performance due to the rpm drop and to get the rpm's back up you have to add more cells, hence more weight. Save your money and buy the Mega 2T and the fan for the price of just the Kontronik.
