Not even my 36t/48p pinion works with that spur.
Anyone get to an FDR of around 3.85-4.00 without having to hack a non xray brand spur gear?
I've looked at the gearchart from xrays site and I'm assuming it shows the only working combinations with X-ray spurs. Has anyone tried a combination that was a drop in fit not shown on the chart?
I've searched amainhobbies and couldn't find the 69t/48p I was looking for...
Either way, I race blinky at a track where the FDR's are around 3.85, I race at others where fdrs are 4.5 and
6. I want to just have one spur gear to cover this range and just have to change pinions.
Ive run a 92/60 in my car I know you can run bigger stuff you just stuck on running 48 pitch?
