1/3 scale Ka8b build
« on: August 26, 2013, 13:29:43 PM »
Alright, time to glue some wood!

As some of you know, I am in the process of moving home / workshops! But I could not go for long without gluing some wood, and while most of my stuff is in storage or in another workshop, I still have a bunch of kits waiting to be assembled!
Temptation was too strong, and out of curiosity, started to build the Ka8 to make sure a few of the parts fitted together well... And one thing leading to another...  :lol:

Anyway, scale for this one is 1/3. That give us a wingspan of 5m, and an expected weight of around 8kgs or so.
Wing profile is a good old Hq (3.5/12).
Construction is all Plywood with a few miles of Pine strips (mainly 8x8mm from the local DIY shop).

I have planned to assemble the fuselage by sections. Middle, back, front.

I started by the middle section, that will support the wing, wing joiner and wheel (100mm diametre).









Just to remember what it is  :lol:



Small tabs and angle gauges are used to set the formers correctly while drying

Education is important, but flying RC planes and gliders is importanter!

The front section comes second, making sure everything is square of course...






And the back section, which is also the rudder post:






While it's drying, started the rudder... Very easy and quick to build... and big!











For the elevator, same principle, so quick and easy.. And big too, so that's handy for my big fingers!  :lol:

A few 8x8mm pine strips added to link the middle section to the back section, and we have what's look like a fuselage!



And even better with the elevator etc added for the look  :D



And that's it for today! Everything is glued with white glue, except for the elevator / rudder, so hopefully, I will have a good straight fuselage tonight!

So far, very pleased with it! one or two things that can be enhanced (plan already changed :) ), but this glider so far, is very easy to build.

Stay tuned for (maybe) more!  :D

Apparently, the 6m one is twice as fun!  :wink:
With 5metres, I should be somewhere in the middle  :lol:  :P

So far, very pleased with the build. Only "major" modification so far, I have added 2 formers in the fuselage, between the wing TE and Elevator LE.

As for the bottles.. well, I need support for the build!  :lol:  (fuselage is straight.. so far!  :lol:  :P )

Thanks Alan  :D
No, just looking around where we live. Main concern, is the workshop (and finding a house of course  :P )

For the build, did more work on the fuselage. SO far, so good!
If I have time, should be ready for covering this week end!  :shock:

More work done this morning, moving nicely  :D
Fuselage removed from the jig to finish the front section and make sure everything was straight (it is!  :D  )

Started the cross bracing at the back of the fuselage. A few photos later!

Thanks guys :)
Yeah growing up fast!  :cry:  :cry:

So, a bit of progress yesterday morning, with the fuselage cross bracing (?) started to be put in place.
Coming up nicely.





With the tail and rudder to check that everything still sound right  :D



And the beast...



I have since put more cross section, and also glued the canopy frame. Looks like a glider now! Next step is to start the rudder / elevator sheeting and I can start thinking of building the wings now  :D
