First run with the Tekin 5100kV Pro2 motor last night, and wow, this thing rips! Started with a 16t pinion and motor temps were just over 100 after 10 minutes, 17t brought that up to about 110, ended with an 18t and temps still low at 115. Running kit setup with 30/30/10 in diffs and no problem with front liftoff down the straight, very responsive to throttle attitude adjustments in the air. Pushing a bit on throttle in the corners and plan to decrease front, increase rear sway bars a bit; the track is short and pretty tight in the turns.
