Hello I am new to R/C flight. My question is about engines, and insuring the right amount of oil. My club offers fuel,to its members, at a substantial discount. It is 10 percent nitro,14 percent synthetic oil and 5 percent castrol. I am running an O.S. la 46. I am assuming that is enough oil, however I have heard of people adding oil. I was wondering if one were to add oil, what type to use. I have 2 stroke engine oil for a gasoline engine. But I didn't know what to use. What you all recomend?
