5s1p A123 w/8L c40 hacker = Wheelie galore

i think that bumper is plastic by the way the chrome has scratched off.

From looking at my own hacker c40 8s it seems the rotor is not segmented but however i believe that its still a very efficient motor with much better construction than a kontronik twist.

in short the twist i would not recomend over a hacker c40 for a number of reasons.
1. the output shaft is very short making using it in some vehicles impossible.
2. the shaft is only 1/8th all the way thorugh using quite small bearings compared to the hackers larger shaft that has oversized bearings.
3. the fins for cooling are not as good as the hackers.

4. its not easily rebuildable like the hacker c40 motors.
