Went flying with my 12 year old son yesterday. We absolutely had a blast. He soloed about amonth ago, and is really flying well (good?). We were doing a little follow the leader (with me following him). That is a lot harder than it looks. I have seen some videos, and those guys make it look easy. Anyway, my son looks at the can of Power Master and says "Dad, what is the other 67%"? I said "what"? He said "if the fuel is 15% nitro and 18% lubricant, what's the rest, the other 67%"? I said, "I don't know. Good question, I will see if I can find out". The can doesn't really say what it is. So, does anybody have an answer that I can give to a 12 year old? He really likes this hobby, and I don't want to steer him wrong.
Thanks
