Kyosho TF2 Spyder - I still have it in pristine condition and doesn't matter where I race it, it does exactly what you want and handles like a dream. 2speed was possibly the worst thing about it. Life expectancy of the 1 way bearing = 1-2 races. Replacement cost of the 1 way hub, $150..
But fortunately, it was optional.
Tamiya Dirt Thrasher - While initially ok. The design of the car would have the gear box lids (they were only really lids sitting on a pre-molded gear box) would lift up under under pressure as the gears valiantly tried to escape.
And sometimes they actually would escape.. creating a spectacular scene of gears/shafts and bearings flying out of the car while it was at speed. Fortunately, it was not expensive to fix and after a while, drilling holes through the chassis and bolting the lids on proved to extend it's lifespan (not indefinitely though)
