Hi Scalecraft, I made a mistake about the forward rake being made 6" more on the "G"model, I found the article that I was referring to and it was the transition from the "E" model over to the newer "F"models and on where it occurred . You were right about the larger wheels being used later on .
I've built a" few" models from kits over the years but only did one scratch built, a Henschel 126 from Brian Taylor plans . It flew good for the few flights I did with it and became a bore after that, all that could be done would be to fly around in circles ! I sold it at a swap meet . I had more enjoyment in building it .
