Building this kit now i know why everyone says it comes out heavy. The balsa in this kit is as hard and heavy or heavier than plywood! It builds easy but what drives me crazy is how GP makes you glue a lot of parts together that should be in one piece to begin with IE: Fuse sides, top and bottom I bet you could save a pound by recutting the balsa with sig balsa.
Has anyone turned a standard 2 stroke where the standard muffler was directly under the fuse and cut out a channel where the muffler goes? maybe even build a tunnel for the muffler?
