Ultima db diff issues
 
So what i was going for when i bought paddle tires a mamba max pro 5700kv and 3s was a dune speed demon but i got 1 good run in on 3s then i stripped the middle gear in the tranny so i bought a couple of 2s's and every run i will strip the diff or the middle gear!
I dont know that to do because my slipper is loose and meshed perfectly.

Is there a diffrent transmission i can put in or do no others fit?

What could i do with my existing tranny to make it stans the power?

all responses are greatly appreciated

thanks

I had the same problem, even running inthe 17.5 class. I swapped out the gear diff for a ball diff, and threw in the stronger idler gear. Any internal tranny gears from the sc(rr, rb5, and rt5 work. With that kind of power you have, i would expect you to blow the rear bones as well. Might wanna look into upgrade's...

ball diff
 
so youre saying that if i get some cvd's and a ball diff ill be set (already have the upgraded idler}

So i havent checked whats stripped from today but i think it is the outer diff gears so if that is the case i will be happy because i wont have to worry about the idler.

i thought gear diff's were more durable?


thanks
