The two-seater Q2 and Q200 were designed by Canadian Garry LeGare, Jewett and Sheehan. [1] While the Q2 and Q200 were based on the original Quickie, the design was completely different. Now defunct, the company sold over 2,000 kits in its lifetime. The Quickie's canard wing used a GU25-5(11)8 airfoil, developed by Terence Nonweiler.
The heavier scraper types have two engines ("tandem powered"), one driving the front wheels, one driving the rear wheels, with engines up to 400 kW (536 hp). Multiple scrapers can work together in a push-pull fashion but this requires a long cut area. Smaller scrapers may be towed by a bulldozer.

Grousers on a bulldozer track. Grousers are devices intended to increase the traction of continuous tracks, especially in loose material such as soil or snow. This is done by increasing contact with the ground with protrusions, similar to conventional tire treads, and analogous to athletes' cleated shoes. On tanks and armoured vehicles ...
