Pappy..
i have been flying a TFGS Jug for four years....at 23.5# A G-45 with a 20-10 XOAR will fly this plane fine, with a reserve safety factor....However, since the G 45 and the G62 are close in size, and share many of the same parts, either would be a good choice for your Jug... Both fit inside the cowl, except the carb opening. You will love this big bird, smooth flyer, and lands as soft as a lady with a baby.... If you would like a pic of my plane, I will need your Email address....
