Hi all. after completing a large design job for Cliff Evans I made time for one of my own future projects.
It is a scale 1:3 Krähe Motor glider Crow in English. It will be powered by an electric brushless motor driving a pusher prop.
The structural computer design is completed. drawings and Laser cut files in progress.
Attached are some rendered images of the my model design in the computer and pictures of the full scale samples
Wing airfoil HQ3514 to 12. calculate mass 6 kg

Re: Krähe (Crow) motor glider
Jilles,
That fuselage looks like an accident waiting to happen. How will you make it strong enough above and below the prop???

Re: Krähe (Crow) motor glider
Barry your remark on the fuse is a fair observation
On the model I have increased the height of both connections a bit. What you cannot see on the model pictures is that like the full scale there are two bracing wires on either side for the fuse starting near the rudder and running to the Wing t/e near the air brakes.
On the full scale this tail frame is a bolt on affair near the prop line
The structural details are the same as in Primary glider design and involves carbon strips as well. No problems here after two years of flying

This should be fun. I was pretty close to building one of these a couple of years back, so I will be interested in your build.

Re: Krähe (Crow) motor glider
collected the laser cut parts from the local Laser cutter last week
A nice Jig Saw puzzle, but I created the puzzle myself so should know where it all goes
Hope to start the built in January after the 1:3 KA6E is completed
Cheers
