Allright guys, I need some input on overheating issues i'm having with FB2. I took the truck outside a little awhile ago in sunny, around 70 degree weather. I went to a local park and I gave the truck a real hard test run on a full set of batterys. I did alot of high speed runs, turns and wheelies in both gravel and some grass. I did alot of small jumps around 4-6 feet high with alot of throttle and braking as needed. There was alot of dirt and dust flying everywhere as I did donuts, skid turns and peel outs so the entire truck had dust everywhere on it

Within in the first few minutes, I stopped the truck and noticed the ESC fan was running. The motor didn't feel too warm so I kept on going as I stated above. I stopped the truck several times through the run and noticed the ESC fan running on almost every stop but I decided to just keep hammering away at it. Finally, I felt the LVC kick in at 3.5v at around the 20 min mark and I checked things out. The MMM fan of course was running and it did feel pretty warm around the casing but then I touched the motor and I nearly dropped the truck as the motor was searingly hot to the touch.

I touched the motor on the heat sink fins again. The motor was so hot that I couldn't hold my finger on the fins for even a second it hurt so much.

Needless to say, something aint right here and now i've got to dig through my setup and see what exactly is causing my motor to run so hot before I take it out again.

I'm theorizing it has to be one or combination of my mods including:

1. Sealing the front endbell holes with screws to prevent dust intake
2. XL chassis and axle extentions
3. Heavier and slightly larger tries

I double checked and I have a good mesh on the pinion and spur and im running the stock 20/44. I had the punch control set to 0%, drag brake at 10% brake amount 20% and reverse w/lockout at 25%. I have no unusual drag or binding on the tranny anywhere that I could feel and everything rolls smoothly.

That being said, what should I try changing on my setup to see if and how that effects my run temps?
