Dozer Upgrade

[Rvjimd]

I want to upgrade my die cast dozer conversion and thought I might try replacing the track drive servos with right angle gear motors or maybe some DIY worm gear arraignment.

Anyone have a source for small right angle gear motors or worm and matching spur gears? I'm dealing with a small machine, so the typical windshield wiper style is going to be way too big. My two standard size servos just BARELY fit between the side frame rails.

I have seen this on servo city but it looks a bit to weak for my application.
