Brushless EDF Tamiya F103GT

[What's_nitro?]

I abandoned the magnetic brake because I could'nt find magnets with the correct radius, and because it locked out the differential which cut my turning radius a bit. It made the tires slide instead of roll and the foam wouldn't last long like that.

The only problem with a disc brake, as well as any other brake, is that it needs to be able to stop both sides of the differential or it wont do much at all. Usually this means replacing the differential gear with a brake disc with holes cut out for the diff balls. I thought about this method but I don't have the tools to be precise enough in making the custom disc, and I don't think any stock brake disc out there has the holes in the correct places let alone the right size hole in the center to fit the bearing.

I think I will try to modify the stock differential gear with some metal rings on the side for a disc brake setup. Some standoffs to hold the calipers, a servo, and voilla! Done! You're right- it does sound easier when you're typing it!

Use a pinion gear meshed with the diff gear like stock and attach the disk brake to that, at least it will brake like a stock electric motor vehicle would.
