I still have the 50T on there. budget constraints have slowed down my project.
I need tires before I can get serious, and I need a charger worse than tires...
I think Phildog is running a 35T on a custom center spool.
Easiest bet for huge pinions is head to the FB page, and get one of the extended motor mounts. I think you can fit a 35T pinion with it. That is probably the direction I will go before I try to make a custom spool.
