gearing up or using higher # of cells will cause heat

[Rampage]

if i change my gear from 10 tooth to 14 tooth will cause more heat


or changing from S6 to S8 ,


the motor can handle 8 S but i wonder which one will cause more heat

gearing up will cause more heat and upping the voltage without adjusting the gearing for the rpm increases will also

^^ In general, yes.. but I think more specific info is needed to answer the question. Which motor is being used?

Every setup has a "sweet spot" or workable range where temps are lowest but output is maximized.

Each brushless motor seems to have a certain rpm range where things work best. For example: a Castle Creations 1717 has better stall torque than a Castle Creations 1520, but geared for the same speeds in my XBE, the 1520 runs coller.

I have several cars, and quite a few brushless motors. I never ceases to amaze me at how some motors seem to just perform better in certain cars than others do. The overall vehicle weight, number of poles and your driving style also comes into play.

I'll assume that you're using one motor (let's say the stock one that comes with the XBE). Try to find a place to run for 5 minutes doing speed runs back and forth, and measure temps. Change gearing and then repeat to find what works best.

Rampage could you post up pic's of you set up?
