From a racing standpoint. I don't see much need for multi-cylinder motors. There isn't much more power needed for racing. I do think it would be a better idea to come up with more fuel efficient motors. .28 motors get horrible economy. I get 6 minutes max on my o.s. .28. Being as I am racing truggy. I can't put a larger tank on my car due to roar, and rc pro rules.

From a bashing standpoint. Slowing down a nitro car is a lot different than slowing down an electric car. I don't think having a nitro monster truck *for example* that does 80 mph is a good idea. It will be hard to slow down from full speed. Could potentially cause some major damage. Especially a run away nitro. The failsafe excuse doesn't always work for nitro either. Its not like an electric where the car just stops. If a nitro suddenly loses its power *i.e. batter somehow comes undone, a servo goes, etc* a failsafe won't activate. The throttle will stay in the open position, now you have an 80 mph runaway rc car. Throttle return springs don't always wok either. As much as you say people should take precautions. They don't.

Planes and boats have there own special places to be run. Cars don't. You can't run your boat unless your in water, and if it runs away your not likely to hurt anyone. In order to fly nitro planes you have to belong to an airfield. Mostof which are located in the middle of nowhere.

While it seems like a good idea I don't feel it to be to feasable.
