GDOT!!! we run the same chassis... so we both know what sort or stress the pinion goes through!!!
THATS AWESOME NEWS!!1 i will check out a robinson pinion if you have had that much success!!!
5s??? why???? the db-17 is perfect on 6s!!! what gearing do you run by the way?
oh and where do you get your robinson pinions because i cant find them?
Sorry bud... dont think he dabbles with carbide haha but titanium is a possibility...
they have dealers everywhere i can think of. heres their pinion chart http://www.robinsonracing.com/catalo...n.html#one-mod
the 6s seemed to crazy for me but if i try the cd like you did then it might be nice. the 5s is perfect for my driving and where i bash it. crasy speed and long running with 20t on a 44t spur still. its stock flux parts but used the hd trans gear inside not the speed one
