Brushless gearing

rich67 · #1 10-05-2010

Hi, I am new to brushless motors and need a bit of advice on gearing. I am running a GTB with a 13.5 ex motor in a TC4 on carpet. The 1st temp reading was around 75c so I droped down a pinion to see if it would bring the temp down but it went up

Can being under geared cause high temp aswell as over geared? I was running an fdr of 6 but on the novak site it says it should be 4.5 which seams quite high? and means a jump of about 10 pinions

Any advice gratefull

you always gear up for brushless compared to brushed so a bigger pinion / smaller spur is normal.

Thanks, have done a bit more digging around different sites and it seams to be the norm to gear them high.
