Patrick,
I tried the 1.5 torque limit setting and it just was sloooowww. I then went ahead and set the punch on 20% and all was well with the 1506 Neu motor w/19T pinion. Speed was in the 60's mph.
I then swapped in the B50 5s 7400kv Hacker motor with a 20T and did a single run with the truck dead. I blew the copper traces off my lipo. I soldered on some copper braid wires and the monster within came out. I'll reduce the punch to 30% and call it a day. Speed was nearing 70 mph. Mike RCM CRT.5 chassis stayed planted to the ground.
Thanks for the support Patrick!
