Still moving !
Today, I finished the V Tail  :D

Covering is made with Diacov, and on the fixed part, with the technique explained here : http://www.gliderireland.net/covering.htm





And you can't really see it on the photos, but so far, 3 coats of clear varnish has been applied to the fuselage... Shinny !  :D

Wing sheeting in 0.4mm plywood is also started, photos later.

A bit of work over the week end  :D
Back to the wings, and first, with the airbrakes.

Nothing to say really here, just have to study the plan and do some test fit first. No major issues.







Then, time to start the plywood sheeting of the wing. It's all made with 0.4mm plywood and glued with "impact" glue.
Easy job to do.





The plywood is in one piece, rolled over the LE. Smooth and clean finish !

After 1h30, everything is sanded smooth... You can see the ribs under the balsa and plywood. I think this is going to look really good once the colored varnish will be applied  :D







Et voila ! Tonight, the aileron articulation, and start to work on the second wing !
This glider should be finished by the end of the week now...  :D

Alright, big push this week end on the Ka1 !

First, the ailerons... Really easy.

Separate the ailerons from their supports with a saw or knife...



Glue 10mm balsa on the aileron's LE, sand in shape.
Cut slots for the hinges (Robart type ones here...)





And put in place !
Hidden articulation... Top view :


And bottom view before closing the aileron to see the articulation...

And the big day, when I finally started to paint the wings !  :D
Both wings are fine sanded for the last time, and the colored varnish is then applied.
The finishing will be the same as everything else, varnished.. Lots of coats...  :D



And once dry, fit everything together in the garden to have a good look before covering...

















Looking good !
Next step are the covering, and plug the servos...  :D

Thanks guys !  :oops:

Getting close to completion !
Covering is started and should all be finished this week end, ready to fly (well, almost, have to make the canopy after that!)

Same technique used as for the Opel Rak.

Starting with the aileron :



Masking tape applied on the wing :



Then Diacov :



And the excess is then cutted with a new blade following the masking tape to neat and straight :



Et voila !
Before / After :


And the wing :








Now, several coats of varnish need to be applied.

Finally did the canopy frame this week end  :D

All in brass, and I think that look really good with the varnish finish  :D









Looking good!
Missing is the top frame... Did it, but I will take a photo tonight with the clear plastic hopfully...

And all the excess is then filed down to make it clean.
