refined a couple of issues in the design and added the landing gear. Still not a clue where to fit the radiator.

A little showcase of the fuse.

Just build this little device to check the roughness of the surfaces. Trusting your sandblock is nonsense. Helps a lot in identifying bumps that distort laminar flow.

I am having problems with the filling of the plug. With epoxy microsballons and tixotropic additives i get streaks and a two day cure time until sandable. Now with poliester putty the result is a worst case bescause the poliester putty cloggs in one minute my two meter sanding block. I had to sand all the putty of wasting half a box of mirka sanding disks.

Pics of the horizontal stab plug. Wondering this time how to avoid shrinkage when laminating the plug skin. Hard to laminate both sides in one step.
