Could I use a snowmobile engine on my ULTRALIGHT airplane trike?

I want to make one of those super light flex wing style trikes.

Would I need a reduction drive if I used a snowmobile engine?

People always say to use rotax motors, and rotax motors were used on snowmobiles so I'm thinking any snowmobile engine is a possibility

my motor budget is about 400$

Sure. Make sure your life insurance is paid up for your next of kin.
