New Novak Brusless System
There is a HUGE thread on the Novak BL system..
Otherwise - I've owned the ss5800, the 5.5R, 4.5R and the 3.5R
All have worked flawlessly, with the lower turn systems having gobs of power. The only few things that were issues have pretty much been resolved car one:
Originally - the rotors were a bit weak. Not so much out of the box, but after a couple of hard heats on the verge of thermalling or thermals themselves, the rotor needed to be replaced for optimum performance. The new sintered rotor is great.
The Original solder tabs were a pain(personally speaking), the new ones make mounting a clean install easier
The fans are weak - My fault. I regularly put my finger into the thing when i reach under teh shell to turn the car off. I replaced mine with MM racing fans and it's all good now.
Size - like ALL BL esc's. The GTB isn't small..
Otherwise, fantastic experiences.. If I were shopping for my next setup. The Novak stuff would be powering my ride for sure..
