How's the mid and topend power? I have run the Ofna 086 and Novarossi 9853 with ODonnells 99 glowplug on 30% fuel. The 9853 was better mid and top end with better fuel mileage, but if 2015 is really good on top, I might try it. The B3 has enough bottom and quick snap for continous jumps and is really smooth, just want to stretch the powerband some more. Its a motor I built from parts with a ceramic rear bearing and is holding very well so far.

How well do the JPs stand up against other motors?

I have a JP21 B5N and want to say that I like it, even picked up another one for cheap from someone on here.. but how are they compared to some of the other big motors that guys like?
