Nice Conversion Bondo! I like it.
There's nothing wrong with the Novak setups IMO. I've owned a couple and they both proved themselves to be very reliable.
In fact, I still have a HV4400 setup. Have even been tempted to try the HV4400 with the Mamba Max Pro that I have on the way.
Do you know if the old style HV4400 can be upgraded with the 5mm shaft/rotor? I'll have to check into that.
What Lipo is that? A 4S 5K 20C? Is there a LVC in there?
Also, Did you lock the tranny in 2nd gear?
Mechanical Brakes?
Hmmm...........Wanna race my E Revo? It's a 4S setup too.
