RE: Phil Krafts Original Ugly Stick
No, the plans from RCM are not the original plans. They are similar in construction/dimension but, are updated in the wing spar area to allow the builder to use iron on coverings. The original was covered in silk and dope and that added to the integrity of the airframe. Other areas are changed as well, such as the original was designed with a cowl and was drawn with a Veco .45.
I posted this thread for those of you who are vintage buffs and wanted to see the actual real original Das Ugly Stik. The one that RCM has came later and was in fact updated by Phil Kraft, but it was not the first one. A lot of folks refer to the Jenson kit as the original, but in fact it was not. It was the first commercially available kit of the airplane and it was changed/updated from the original Grid Leaks Plans.
