Took my H8 to the local park today for a run with my EB4 and some other cars. Halfway through the first battery pack my pinion stripped...again, 2nd time it has happened :mad:

I've got an Aon 4900 sitting at the LHS to replace the Mamba 8000 I use currently so what pinions do I get that are going to survive more than a handful of runs running that motor and Atomic slipper gears?

with the Mamba try some HPI Micro RS4 Steel pinions...


I think the orion ones are brass and weak and some others.

Picture for you all to have a good laugh at :D
I've now picked up my Aon 4900Kv so I just need some robust pinions and I'm set...I hope :rolleyes:

Sick, man thats almost smooth. Hopefully that 4900kv will keep you running.

use the stock slipper, I run the 4900 with an 8cell and have not stripped it. metal on metal contact is not needed unless you constantly stip gears.

Yeah maybe I will put the stock slipper gear back in there. I'll try and source some stell Micro RS4 pinions as well and see what happens :D :eek:


What size pinions are most people on the Aon 4900 using?

i had the same problem with atomic metal gear...use the stock slipper to resolve the problem...

If I do that will it not end up shredding the standard slipper instead?

no, unless its a bad mesh or locked slipper+nasty jumps. It takes abuse or tons of power to shred a gear. You should be fine...most people are

I agree-the bigger of the atomic slipper gears stripped my stock pinion gear. Then, when I got the AON 4900 I installed it with a HPI 13 tooth steel pinion. This was working fine until I landed hard trying to clear a 20 foot gap jump and must have shifted the motor for a second because a small section of my big slipper gear got chewed up. But the HPI pinion was fine so I re-installed the bigger stock plastic gear and i've had no problems since-I also think it feels smoother and is a little quieter as well! :)

P.S. I installed a fresh Atomic slipper pad when I did this!

...i tell you mate that AON moves even a little bit and it chews whatever is in its way...lol...we could make a horror movie with it...I will get Tom Cruise to play me ;) Speaking of Tom Cruise maybe i SHOULD put my stock units back in...maybe that will at least make my H8 RUN properly :mad: Of course I have absolutely NO clue of the connection between Tom Cruise and my slipper :confused:
