The internet forums are great but you get too many opinions and info and you get pulled one way and the other.
Times like these I love my electric planes, pop a lipo in and fly! but I love the bigger planes and anything above 30 size in lecky plane is not cost effective.
I was just told ( from the FG site) that Motul 800T should be run on 50:1 and anything less creates deposits! See what I mean more *&%$ info!!
