Heat-Problem

[Marco]

hi guy's

i run a fantom 10x2 checkpoint can with ib 4200er shv cells and a sphere comp. in my yoke, as you can see on the pic i cool my esc with a fan and cut the holes to cool the motor.
i have it geared with the original spur gear 84t and a 14t pinion.
i diden't those prob's with the xx-4, why do i get them here? is my gearing wrong or what? i don't get it.

what do you guy's mean?

I dont have the car anymore so its been a while, but you sound way under geared to me. I dont own anything like that sort of pinion so I was running around 20t on a 11x1 (from memory) and it was fine.

Someone will jump in who actually runs the BX and help you more than I can, but your motor would get very hot if you are undergeared.

Just a thought, you dont actually say what the problem is, just that it is heat..

If it is the ESC then that could be something else. I have run the sphere with a 3* and it was fine, I ran it with a 10x1 brushed motor and it thermalled out on me.

Yokomo gives a 17t pinion with the kit expecting people to use 10x2, 11x2 motors so I would guess you are way under geared. I run a checkpoint 9x2 in my BX and I use a 16t pinion with no issues.............

Bathy uses 17 or 18 in his cars. They don't get stupid hot, but still have plenty of beans!

Is your tranny free enough ?
I have read that belt tension is too high with the stock settings.
