losi xxx cr diff melt down

[migsy]

Hi guys, Any of you lot using a 7700kv in your losi yet?

Had a practice today for this weekend coming but as things were running fine, disaster struck.

My diff had only melted in the gearbox and caused the losi to completely stop moveing forward. any of you lot had this happen with a high powerd brushless yet?

I did turned out i wasnt seating my bearings correctly inside the diff causing the diff gear to melt its also best to buy a new set of carbide balls and diff rings.

Might off been too loose or too tight? As ash said, when rebuilding, best to do the lot to be safe (you can flip the diff rings though so you get 2 runs out of them so to speak)

I used to hate the losi diff gears, seemed to be made out of cheese.

when i get some time now i'll put all new in the gear box.

cheers.

I've recently got a CR diff to run in the back of my X5, I liked the idea of a tiny amount of slip to protect the diff on the copper washers but I can't tell really how to set it correctly anymore. Used to trap a wheel and spur and see whether the diff or slipper slipped but now you can't tell if its diff or rings slipping?

Mine was slipping after about 10 meetings, mainly running indoors. I rebuilt it, just cleaning, and it was fine afterwards. I'd say it was slipping and heated up.
