What about slightly elongating the motor mount holes to allow a smaller spur to be used? Maybe tamiya will release different gears to lower the internal to around 2.0??

Just saying.

I expect some update parts, but till then....I'm running my M03.
I'm missing something here. If a 76 tooth spur fits. Why wouldn't a 68 tooth? And instead of that stupid motor adaptor. Try using some tamiya spacers instead. It should hold the motor in place just fine. That should/ might give the proper clearance needed for the larger pinions.

Because you are out of adjustment to make the gear mesh tighter already. When you go to a smaller spur, it will open it up even more.

Further slotting of the adjustment holes would help.

Who makes a 68 tooth 64 pitch spur? Just curious.

Smallest 64p spur gear I've seen is 71T. I'd like to know if there are smaller spurs too.

I will stick to my TB03R. I'm no longer impressed. What happen to the short shocks? I think I'll just try to put 418 arms on my TB03 and call it a day.

I don't have a TB03R and it's been 2 years living with direct drives and belt drive kits, so the TB04pro is a welcome addition to my garage. Always wanted a modern shaft drive kit but not the TT01/02 series or the TC4.

So the real measurement is 20.90mm and the max pinion size without tempering with the sleeve is 49T...for a 3.88 FDR
I will correct my first post.

You can see in the middle pic that the motor/pinion is already as far over to the left as it can possible go (see the screws in the motor mount?). If you go a smaller spur, the pinion won't reach and they won't mesh.

Oh, the pics didn't come across. Check out the pics just one page back.

Sorry if I was not clear enough English is not my first language
I only use 64P for my calculation and as you can see in the picture the motor at the maximum position is almost touching the chassis and gearbox...

You may be able to go a teeth or two on both ways with more dremeling but not really more. So 3.5 or 3.6 may be doable but I think the effort is not worth it...better concentrate the effort to make a conversion with a new motor mount.

I have a 68 tooth spur on my evo5. I don't remember the brand. If it helps I purchased it at NorCal hobbies. And going up in pinion sieze, it should mesh. I would definetly open the motor holes up anyways. Won't hurt anything, but will make your life a little easier meshing gears

It's too early judge this kit. Lap times will tell if the overall package is crap or brilliant or just typical tamiya tub chassis performance.

too early? timing is just right. If you cant hit the correct FDR.. i dont care if Masami is driving the car, your lap times will suffer.

yah but that still doesnt leave it as a viable option for GT2 class participants here in the U.S.

It probably was only designed to be run in TGP. People still compete with brushed motors there.
