We’ve been trying to avoid the issue of stripped gear and it seems that the recommended way (going for softer, low-friction belts, soft spur gears, and one-piece engine mount/new chassis) is the only way. I tried the EVO-Workshop multi-flex chassis though and it works as fine! No problem even when I used the original rubber belt, default spur gears, and the original engine mount. Give it a shot, peeps!
(BTW, I think the new Mugen Seiki chassis doesn’t balance quite well, with the below-engine hole filled up…)
