One of the only issues the big Losi 5IVE-T has is the fact that there is no bracing between the motor and center differential. In the event of a big crash (or keeping the throttle pinned while landing off a jump), the flexing of these two components can result in chipped teeth on the spur gear.
Vertigo has successfully addressed this issue with the release of their Gear Mesh Plate, a small brace that ties the motor mount and center diff together. Simple, yet effective! Get one and keep those teeth intact!
