Re the Xray.....sounds good if my maths is right then on the Xray to get ratios between 4 and 5 to 1 I'd only need pinions from 33 to 41 tooth in 64p on the standard 93 tooth spur? I assume there would be no problem getting a 33 and a 93 to mesh?

The 93T on the Xray is 48P! The equivalent 64P is 128T.

Default stick with shaft

You should look for cars with shaft drive, a fully hopped up tl 01 with long arms are quite fun or maybe tb 02, if you want one all ready and souped up then tc3 factory team would be a solid choice. the car seems to like stock motors, i find tc3 can be very unstable at high speed compare to japanese made chassis such as trf 414. tb 02 have a good all around grip, but you would have to soupped it up, if you have the resources then might i suggest tb evo III

The S1 version of the Schumacher Mi2 is fitted out for stick pack batteries. Add a Schumacher 86 tooth spur and you'll find that ratios for 540 are no major drama. Add to that the adjustable internal ratio for even more flexibility.

Probably the best belt drive transmission going around at the moment - so the Mi2 is a winning choice on every front for you.

The stock spur gear on the yokomo SD (including the CGM) is 70T 48dp. With this it's quite hard to get close enough for a mod, so I assume if you want to put a 66T spur (or lower) you won't have any problem, and you can reach the ratios you need.

Lots of us run the TA04 in the GT3 class here in the US, which is also limited to a 540 motor. You need to be somewhere between 5.0 and 5.7 depending on your motor, so a in 64 pitch, a 116 spur and pinions from 45 to 50 work quite nicely. In 48 pitch, buy 83-86-90 spurs and 33-34-35 pinions and you will also get the correct range of gear ratios. BTW, neither of these combos require slotting the motor mount.

ok ... just checked my TC3 ... 88 tooth 64 pitch spur and a 44 tooth 64pitch pinion fits nicely plenty of room to go bigger on the pinion .. and 88 / 44 is right at 5 to 1 ... I dont have any bigger pinions or smaller spurs to try ... sorry ... but the motor cam was just about in the middle at 88 / 44 .. so going to 50 or 52 shouldnt be an issue and that will drop you to 4.23 to 1 with the 52 .. if they dont fit ... just get a smaller pinion .. I think I have seen 64 pitch pinions down to the high 60's .. so getting down to 4 to 1 shouldnt be an issue with the TC3

have fun racing

Schumacher = great looking car but no supplier worth taking note of in this country.

Default Tamiya ta04r tuned .!! chassis

well from wat i haved used recently racing with the 540 motors
on my TA04 R tuned u can use 108 spur(64p) an wesh it with a 51 pinion(64p) wthout any mods

also if u get the tao4 (which ever versions) u will need some time to make the drive train a bit free ......
u will get a ratio of 4:5 but if u go higher wouldn't that burn out the motor ?? coz u will b running a rollout of over 43 (depending on tyres diameter) ??
i've have taken it up to a roll out of 45 .... but the motor would burn u if u touch it after a race ........!!
oh well
just my 2 cents !!

Sounds great but Yokomo like the Schumacher in NZ is few and far between, thus far the only "top shelf" cars I've seen in stock are TC3 Team car the TA04 TRF and the Xray.

112T spur with 49T pinnion and 1.77 internal pullies.......thats 4.04. But you can see that the spur and pinnion aren't even touching on max adjustment.....I reckon you can proabaly go to 53-54T pinnion with the 112T spur......

One thing to be wary of...using 1.77 pullies requires a 3 hole mount onto the layshaft...as far as I know Kimborough, Tamiya, Xray, Trinity (maybe) spurs are the only ones that fit.
