Rc Fuel Faq
Isaac:
I e-mailed you privately with some thoughts.
In a nutshell for everybody else; In the smaller Webra's I prefer low nitro and high winding props. Webra engines tend to be higher in compression to many other offerings and are well suited to low or no nitro fuel. Most Webra's are big bore and short stroked which means they like to wind up rather than be lugged down with a larger diameter prop. For instance on a Webra 50, I liked 10x6 props and a 5% nitro/ 20% oil fuel with at least some castor in it. I can't recall or find my spec sheets, but that combo turned considerably more than 14.5K, with incredible throttle response and all around friendly running habits.
