RE: RC Guys Super Decathlon coming
Andy I had to lower my engine from the sugested dimensions 1/2". My motor mount would have almost been sticking out the top of the cowl. All I did was move my line down 1/2" and then tried the cowl to see if all my lines lined up. Kind of a weird way to do this but the dimensions in the instructions arn't very good or are for an earlier model. Get rid of the manual and go with your instincts.
