I figured it might b a bit much, but when I go back a year later this is my reference.TMI on the mod-1 explanation. Enough to scare anybody away from doing the swap!
But seriously man, great information.
Just curious, what 48p spurs will go in there, I mean by brand/type, not size? I’m sure your RR pinion is so much better than the Rlaarlo ones it’s crazy, was wondering if a quality 48p spur was available from RR, Tekno, Saga, etc.
The simpler explanation is to find a Mod 1 gear set that
- Has a Center Distance between 52 and 65 mm, which is the same as the TTC.
- The spur gear has to be less than 42mm Outside Diameter.
- The pinion has to be less than 36mm Outside Diameter.
I'm using a 5mm motor shaft, and the 48P choices are a bit limited, but I found some on Amain. RR goes up to 45T and Maclan goes up to 35T.

There are more 3mm shaft options, up to 47T.
There might be eBay options too, but I wouldn't use them.
I also pulled the cover off the car and the nylon gear looks OK. I think the motor moved a bit, which is my fault. The first replacement screws I used were counter sunk and I should have used cap screws. The counter sunk screws don't have enough bite on the mount. Those are in and I will see if I can get better than 48mph in a straight line. The straight line puzzles me.... a lot.
