I want people to use this simple mod and fall back in love with their TT01.
Your spur adapter mod is very timely for me and is a great idea. I picked up a TT-01 just to run in the Canadian TCS race this Sunday. Normally I drive a Sakura Zero S in the sedan class, but of course with the TCS I can't run this car.
The proprietary gears that Tamiya forces you to use are a PITA and the lowest FDR that is possible without the mods is a crummy 5.11. The fast guys here are in the high 3's and low 4's so that ratio just wasn't going to be competitive. There is also too much slop in the drive train and I'm finding that the spur gear moves around too much and rubs the back of the chassis. This ruins the teeth in the end and the noise increases. More noise = slower speed.
I decided to stick with the Tamiya aluminum motor mount and I'll play around with spur/pinion match-ups to alter my FDR. I'll try the 4.68 and see how that goes this Sunday.
