motor choice...

:032:
Hello all,
I need a new BL motor, and wondered what to buy...
I actually run a feigao C9L + 9920 controler. I want to go to lipo to increase runtimes, and i wonder what would be the good choice for me...
I only run 40series wheels/tires on my E-maxx, 14cells (4s lipo to come), and don't have the Strobe slipper (can't use spurs under 66T)...
What motor to choose, considering i want it to stay cool with the 8000mah maxamps packs??? And what is better between wiring packs in parallel or in serie? >>> I search for sthg as fast as my feigao 9L + 14 cells, but a 7xl will be less fast due to its rpm... (i can't go with 51T spur, the less i can use is 66T on the RRP slipper...)

Tnaks in advance for your help!
:eek:
