i spoke to dave a long time ago and he sent me a picture i think it was last sumer of the edge at a show and stated it will be the same size for same engine as the extra. At taht time i had my extra on order for a long time so now that i have the extra im not so sure the edge is going to be light enough for a 1.40 however maybe he is really going to try and keep this one light. But i do know it is the same size as the extra. And supposed to fly really nice
