RE: KMP Stuka-build details
Great work from everyone!
Prekin, your setup is very similiar to mine. I have a DLE30 on my D model with a scratch built cockpit as well. My plane came in at 18lbs and flies great with the 30 up front. It takes off in about 50 feet and has tons of climbing power. Plus, it floats in for landings. It's really a great flying plane.
Regarding your question about balancing weight, my plane needed 3oz of tail weight to balance.
