Thank you for the link. I know that there is a lot of work. I dont want to built full scale. It will be my first old lady.

At last the finishing begins. The fuselage top is skinned in .4 mm ply to blend in with the wings. The cockpit and canopy are painted in flat sky grey acrylic. The rudder push pull system is installed via an indirect 180 deg bellcrank drive. Elevator control is via a carbon push rod to a brass elevator control horn. Access is through a slot in the rear balsa floor. The tailplane is mounted on a balsa seat with steel front pins and a 4M nylon bolt into a captive nut. The fin is attached with a ply tongue located in a ply box and at the rear post a 1mm steel pin mounted in brass tubing.
The diagonal upright into former 7 is supported by a balsa fillet which helps blending the covering at the angle change in that area. The transition under the fuselage wing seat aft from the 0.8mm ply at former 6 is a thin balsa fillet. The covering is in Oratex which works well on compound curves.
The final rigging check is done with wings and fuselage in the garden. The covered empenage are rigged and checked for alignment. The fuselage is covered in four sections with all overlaps going downwards. The radio and servos are fitted and checked. The three servos in the fuselage are Hitec 645mgs.

Thanks Cliff, as you say not to far away to completion. A slow build hopefully gives time to get it right. None of these so called "professional " builds for me. Regards John.
