Just got my DL 50 for my 28% Ohio models Ultimate. Installed a Biela 22x8 carbon prop, used mounts and silencer supplied, primed and choked it...started first flick!! All I can say is the big boys better watch out as this motor has exceeded all expectations. I've tried many makes of petrol engine 3W, Fuji, ZDZ but this one tops the lot without doubt in my experience.

Awesome.
