    Status: offline     		I just bought a different pinion gear for my HSP Brontosaurus. Its upgraded to brushless, and I changed the spur to metal. I bought a Robinson Racing 18t pinion, but the meshing is very poor. I checked with the plastic spur and its the same bad meshing. How is a 48p spur not meshing with a 48p pinion? What do I do? Do I need a different spur? Can I put a different spur on the HSP? OR is the pinion not good?

    Status: offline     		I have never had an issue with meshing the gears, and i got a nice amount of wiggle, but the pinion was smaller in its teeth, very slightly, but i was thinking it was just me, but I now know its that the spur is metric, slightly larger teeth. At full throttle, pinion skipped and when i looked, all pinion teeth at 45 degree angle, so at some point the bite of the gears was bad. Has to be the size.
