motor shaft diameter

[ezhitz]

Hi I want to put a 7S motor in my predator rigger to run on
2S lipo and i see no stock on the 1\8 dia motor shaft but there is
stock on the 5mm! Whats the difference and why pick one over the other.
Thanks Jack

the 1/8 shaft will bend, it's just a matter of time... I have done it, twice.
get the 5mm shaft and be happy.

motor on 3S lipo?
