A big problem with any vehicle will be battery life. A stock Losi micro with the NiMH won't last very long, lipo would help a bit, but then you run into LVC issues and the higher sensitivity of lipo cells. Unless you want to have someone on staff just to be battery swapper and charger, this will be a challenge.

The vehicles will need to be much slower than a stock Losi micro too IMO.
