I've been looking at engines for a UL heli design. There is a dizzying number of options to consider from water cooled, air cooled, pull start, push start :), snow mobile, motorcycle, airplane, weed eater... you get the picture. For single seat, high HP/Weight ratio that meets UL requirements, what works and what doesn't? Are all engines equal? and if not, can they be converted to be?
