540 adapter for Neu 1107?

Since it has not been mentioned, you really need a motor with a 5mm shaft for the crt.5. No slipper and the steel spur will kill an 1/8 shaft quickly.

I would go for the medusa motors for both apps. A 50mm with an 1/8 shaft sounds good for the tc4, and a 50mm with a 5mm shaft for the crt.5. You could go up to a 60mm motor for the crt.5, It will draw a bit more but can handle more load if you want to gear up.

I successfully ran a tc to mid 70s with a feigao 380c motor, so I am sure the 11 series neu can do it. You may not fit a 15 series motor in the tc4, due to the larger than std 540 diamter can, 39mm vs 36mm.

Medusa motors are 36mm diameter, so they fit a little better in tight spaces. Plus you can get 2 medusa for the price of 1 15 sereis neu.
