Etti - Below is the Schulze cabover proprider I drafted at 1:5.2vo scale.
I am very enthusiastic about building this German racing hydroplane and your 3D printed König motor files (with Martin's PCB-AB plan) would be the perfect solution! "This would bolt right on and be totally dialed in", as we say in California.
How can I start this project, can Martin (martimcfly) send me the PCB-AB plan? I've tried contacting him, but no response yet.
My 3D Fusion 360 skills are not yet ready...
Can you email your 3D Konig printed plan .STL files?
I can email the PDF of this Schulze plan. I know it will not fit the 152vo rules and registration, it is for fun building and running.
