I had the DPM Edge with a Moki 2.10 and it was 15 pounds 3 ounces. That G62 is way too much weight (you'd have to add tail weight and further increase the wing loading). I'd save it for a 84-87 inch air frame. Sell the Extra and get a bigger bird. A light weight 40cc gasser is the max I'd put on it (and then you might as well go with a light weight 50cc). DP designed these for light glows, like YS 1.40, OS 1.60, Saito 180 etc. He's a weight savings freak.
