The Losi ones wouldn't, because the chassis is offset so one guard would be too big. The 808 chassis has slightly angled sides, but the side guards are probably too big. The 808 chassis is probably even narrower than the Losi.

I reckon that you could easily make side guards with the mesh that is used for car repair, mould it to the right shape, cover it with fibreglass, then screw it in place. Actually, you may not even need the fibreglass covering, the mesh is fine enough to stop large clumps of 'stuff' getting through, but you still have cooling.

I will be doing a modification that allows quick battery removal, though I'm still working on the design.
