You dont have to sell me on the fuel savings... I know it, i fly large gas planes (50cc) and 700 size gas helicopters (30cc) and I would never even dream of putting a big glow in them.... its just on this plane that I have a saito 1.00 on, to get the same performance in gas I owuld need to go for at least the FG-21 which is rediculously expensive ($500!!!) for a 60 sized plane... and it would weight more and Id have to mix the special fuel.
Not worth it in a small plane for me but thats just my view. Im glad you are happy with yours.
