I had a drive of my Friend's 710 today with a Max Power MX12S3 modified by Fantini. I must say i was very impressed. Awesome power all through the range. Temps were around 220-230 (85 degree day) and it made around 6 minutes run time. With the performance i saw, and the fact that it is Nova based, i'd definately consider one.
p.s. There is something about JP's though. They are the real deal
