XVL with GTB and velociti 6.5 seems to have high temps..
My xvl with GTB and velociti 6.5T seems to have high temps i would think for my pinion/spur gear. My battery is a max amp 2S 6500mah 30c Lipo. MY pinon is 18T and spur is 83T. After 15 min of speed runs the engine temp was 151-155 degrees when i point the sensor to the center of the motor (inside where the engine mounts-not exposed). But on the outter sides of the motor where its exposed my sensor reads 95-104 degrees. Which part of the engine should i read the temps from? (using duratrax infared temp sensor)
In my experience temp guns don't work too well on reflective surfaces and you are better off just touch testing it. If you can hold you hand on if for a few seconds its probably OK. 15 minutes is a long run time for a mod motor and would expect it to be quite warm.
