Both.... plus keeping the transmission together, keeping the tires on the wheels, keeping the bearings from melting, etc.
Don't know what technology they used here. But if I were trying it, I'd guess four 10,000KV brushless motors with axle bearings, one on each wheel, direct-drive; solid-rubber tires, and a single ESC that would make your eyes water. Plus a radio that had at least a mile range on the ground (aircraft radios have that range, but only because the model is up high).
Or, to cut to the chase... no electrics at all (except radio), freewheeling wheels... and a small turbine engine like they're using on model jets nowadays.
Those Associated guys are probably encountering problems we never imagined.
