Thanks for checking in Iron Dog, much appreciated.
You know I'm thinking this plane would be about perfect for a DLE20. How does it come out balance wise? think the DLE20 would require tailweight? Can you post what engine you used and how much lead you had to put in the nose for balance. I might be interested in one of these.
Are there any paint schemes besides chrome?
Hi Jeff, the blue and chrome prototype seen on previous pages is powered by a YS 1.20 which required the flight pack battery to be installed just forward of the tailwheel for proper balance. My airplane seen above will be getting a DLE 20 but it has not been mounted yet. I don't know how it compares to the YS for weight but I imagine that I will be able to achieve the proper CG using battery placement and will not have to resort to any dead weight. I would rather not have to put my battery in the tail but we will see! I will be sure to post my results here as soon as the engine and other components are installed and I have an idea of what is required.
On a related note the fiberglass cowl is molded about an inch longer than scale to allow lighter motors to be pushed forward a bit if necessary. The prototype only weighed about 9.5 pounds and would fly just fine on a .61 size two stroke or .90 size four stroke for those who just want a mild sport flyer. The extra inch in the cowling would help some with balance and does not effect the appearance at all in my opinion. Please note that my cowl has been cut back to the scale dimensions since I will be using the heavier DLE gasser.
Regarding paint schemes there are not any scale ones that do not include a bare aluminum fuselage for "Czech Mate" or "Perestroika". There are other modified Yak racers with various paint schemes but none of them with the cowl/canopy arrangement shown on my plans. I am working on revising the plans so that those other versions could be built but it will be a while since it involves making the tooling for an entirely different cowl and canopy. I am also adding flaps to the design for those who would like to have them. Here are some examples which could be duplicated based on my revised plan when I get it finished. (It may be a while!)
