what kind of fuel do the above three engines burn? Will 10% still cut it?
Not for a YS engine. These engines need high nitro to run like they were designed to. I run 25% in my YS 120, but I know others that fly 30% in they YS engines. I tried to run mine on 15% once to see how it performed, and to put it nicely- it didn't.
