Looking for opinions on 2 power systems from hobbywing this is what i want to go with so please limit opinions to this. I'm looking at the EzRun WP SC8 Power System Combo w/ 3400 kv now i know it is a little high but i'm also not looking to destroy my driveline, on the other hand i'm also looking at hobbywing quicrun 8bl150 and quicrun 4074 2000kv my question is will this 2000kv be to much for my driveline? I have seen another guy run the wp sc8 combo on a tmaxx and he liked it but i want to spend wisely and get speed and torque. I will also be running robinson racing 65t slipper kit, and still debating if a robinson racing 20t pinion would be the way to go.
