Yeah the brass looks very good with the varnished wood. Nice!

Thank you both  :D

Alan, no jig at all.. Tried with a jig, but spent more time to try to keep everything together than soldering !
So, paper tape and fingers to hold all that (well, burnt fingers now...)
Just a good prep workand that goes very quickly.

I just have to glue the clear plastic, then glue the brass frame to the wood...

Instead of gluing the plastic sheets, I'll try to have a go at nail them...

Ok, somebody reminded me that I never showed the finished product !  :oops:
Checked all my threads, and yep, forgot!

Ka1 is finished for a while now, just waiting for the maiden flight which will certainly occur during Retroplane at this stage.. Just to add a slight stress to the process!  :P

So, here are the photos!











The happy pilot come from Premier Pilots ( http://www.premierpilots.net/ ) and came with full options! Cap, but also parachutes, leather helmet and googles, leather coat etc etc! Very impressive, and the best 1/4 scale pilot I ever had!!
Fits the Ka1, but also the Ka3 and Grunau like a glove ! (I'll take more photos of that a bit later)





And with the Retroplane flag!  :D  :P

Looks great Fred  :D  :D . That Premier Pilot certainly looks good. Where can I get one of those Retroplane flags from (or windsocks for that matter). My K8 is progressing. Will post some pictures soon. The way things are going it might not get its maiden flight untill retroplane as well.

Thanks you both  :D

Alan, for the flag, not on sale, they are Limited edition collectors  :D

But I'm sure Anthony can sort that out for you, or someone else for flags and Windsocks  :D

And the Ka1 fly !  :D  :D
Ok, the first flight finished by a loooonnnnngggg walk of shame due to a CG way too forward (must listen to that little voice one day!) but after removing around 60grs, flew much better !
Plan is to remove another 100gr to be perfect !
So, the Ka1 is now less than 3Kgs (2900grs after the last bunch of lead is removed...)
Happy !  :D
Back to the Grunau now!

Hi Keith,

I use my usual mix of white glue and Cyano.
Because you have the best of both world  :D  
Strenght with the white glue, fast with the CA.



Fred could you tell me more about your tremendous mix :
which Cyano do you use (liquid, medium...) ?
ratio of the 2 glues ?
...

Thanks
Claude

Salut Claude,

very very easy  :D

It's not really a mix, but I put the white glue, and on top, I put a few drops of Cyano (medium for me, but works with any Cyano, just be careful not to touch the CA nozzle with the white glue. That do some sort of spaghetti thingy, pretty annoying to remove!) evry 2 or 3cms.

Like that, when you apply the pieces together, they hold together instantly (Cyano), but the final drying occurs when the white glue is fully cured.
The best of both worlds!  :D

Hope this is clear enough, but really, nothing mysterious  :D
