I bought a Mazda 808 Couped when they first came out. It had the rotary in it and I loved the engine. It had lots of power (burned out two clutches), and would just keep accelerating. I had it out in Southern Colorado by the Sand Dunes national monument where there is a stretch of road that is flat and straight as an arrow for several miles. Got it up to 130mph and it was still accelerating so I backed off. Not worried bout the engine, but if I had hit a paper cup, the car would have disintegrated. If you could get one for RC that had the power to weight ratio that mine did it would scream.
