Brushless set up for a new guy

i agree with the other guys about the novak hv. i have got one my self and have had nothing but trouble . thermal shut downs even when use the reconnend pion and spur gears from novak . had to go to 12pion and 72 spur to fix problem .but then you lose speed and get alot of torque . iam also looking at going to the 8xl and warrior .
