Novak velociti light 5.5 gearing in X5

[dentmaster]

Hi,

I've been running a 'full-fat' 5.5 novak velociti & GTB controller with sintered rotor geared on 18:108 with no temperature problems and plenty of speed.

I've been trying the velociti light 5.5 and I've found it get's much hotter on the same gearing. Is this normal? Should I go smaller or larger on the pinion to compensate?

Cheers,
Mark
