RE: B&S 40cc, 4-stroke recipe for success
Captain, It will be scratch built. Dave Johnson drew the plans for me a long time ago but in 1/4 scale. I have enlarged them to 1/3. I have a thread started under "scale aircraft" titled Aviatik 30.40 it's been awhile since I posted anything new since I am trying to finish my SE5a( McCuddens) first. I just wanted to make sure the engine was going to work so that's why I did the conversion now. The Aviatik should be a fairly quick build once I start the framing.
