THE ENGINE CHALLENGE - Create an engine that can power a car or some other vehicle. There are only two rules: - Must be a successor - Engine must be seperate from the wheels/props, powering them from a central unit through the use of gears. You may go as complex as you like, create a gearbox, or a whole vehicle to go with the engine, just dont stick a jet on the wheels and call it a day, its gotta work like it would in real life. Engines will be rated based mostly on efficiency, but also ease of use compared to complexity (more complex engines can be harder to use without losing points), Really good looking engines get bonus points! Participants get upvotes, and the winner will get an upvote, possibly a follower, and a custom replica airplane of their choosing. Check my profile to see what I can do.

*NOTE: ALL SUBMISSIONS MUST BE IN BY MARCH 5th, and then I submissions will be rated.
