The new steel pinion I ordered was delivered today.  I decided to split the difference between 13t and 15t and went with a 14t pinion.  I’ll be upgrading the 540 motor with something soon which is another reason I wanted to upgrade from the aluminum pinion it came with.  It looks like the original pinion has some wear on it....

Oh I miss this on first look, any info for 13Ts? I only had a steel 17T & couldn’t find anything smaller in steel. Mind is currently running a standard 15t but is too fast brushless & over heats 540s on grass with the slightly bigger Boomerang wheels. I’m looking for a steel 13T now.

Get a steel 13t pinion in 32dp. Its imperial but its almost identical to 0.8mod. I have one i run in my thunder dragon. It's a little noisier, but works well.

Took it out for a spin last night and got a decent photo or two.  That gravel gets everywhere and the dust boot on the BZ is almost useless as it needed to be disassembled too.
