I heard that it's wrong but all I notice is a little noise, kinda the same as a nicked spur.
I'm amazed you can run a 48dp pinion with a 0.6mod spur. They are VERY different. 0.6mod comes out roughly the same as 42dp.
0.8mod (which is what some of the basic Tamiya buggies still run) is about the same as 32dp.
0.4mod (which is what some of the higher-end on-road cars are supplied with) is about the same as 64dp. They can mesh, but not cleanly.
