HR Gear case for 2WD Stampede

[Fboylstein]

Installed HR Gear/transmission case on brushed 2wd stampede. Ran it a couple times, not that hard and noticed back end was drooping. Gear case broke at both holes where body post mount go into. Any one ever heard of this issue before?? I just ordered a RPM gear case to try out. (See pic).

I've been running a rpm in 5 of my traxxas rigs. 2 r setup for Drag racing with 9000kv on 2 cell and those get beat on..

Thanks!! I heard good reviews on them. Hard to believe the HR case broke so easy. I know I installed it correctly.

Question? Did you have to shim yours?
Thanks again.

No shims but I did change all the bearing to a better grade when I assembled it.. along with idler gear..
