|  Robinson's Steel Pinions too Short?
I cannot get a square mesh with my Robinson's 12T. I am running the RC4WD Machined Gears, VP tranny and plate and HH 454 16T Pullers. I am getting less that half of the pinion on to the drive gear. How is anybody else handling this? I have looked for longer pinions and found the Losi a little over 1/2" (13.7MM compared to the robinson at 9MM). |

Wierd situation! Is the puller shafts shorter than a 540? Never had one to compare too. My RR pinions work well, the motor shaft are flush with the end of the pinions as well. I got the Vp stuff with Axial hardened gears.

Shaft is the same length but on the 454 you have to use an adapter plate as it is a "400" series motor instead of a 540. On such issue if I was using Cobalts but don;'t want the weight.

I'm thinking it's the pullers shaft being too short with the adpater plates installed?? Don't the 12t pinions need some mod to the xr motor plates to make them fit right? EDIT....I type slow.. I bought some RR pinions for my xr but once I got them in hand I thought they looked weak compared to the steel axial and losi pinions... Losi and axial have much more threads for the set screw.. |

Not entirely the same problem but I just swapped out my front gears for RC4WD gears and decided to use the RC4WD pinion they included. I got it all back together and was getting a loud click each time I went from forward to reverse or reverse to forward. Messed around adjusting the mesh for a bit and could never get it to entirely go away. I finally put my Axial steel pinion (AX30571) back on and it was WAY smoother--and quiet!
