Hello All,
I am adding a bit (bunch?) more power to the TT02 and just bought a secondhand 10.5T motor. Looking at a FDR chart and it looks like they recommend anything from a low 5 to a low 6:1 FDR on a fixed timing ESC. Since I am bashing I am thinking somewhere in the high 5's to low 6's to keep the heat down and run time up as much as possible. With that said I am wondering what the largest 64P Spur the TT02 will accept? I have an 85T in there now and there is a bit more room but curious how big you can go?
Thanks.
Cheers,
Jim
You can go to a 50 pinion on 64dp before you need to consider grinding the cover, maybe even more. I ran 92 spur/45 pinion for a 5.56:1 FDR on a 20turn brushed motor in race conditions. However for general bashing I'd recommend 48dp as it's more robust.
