Title: Krick SG38 PRIMARY GLIDER
Post by: Richard Boyd on August 10, 2011, 09:51:26 AM

I have started to build my first retro glider and this was intended to get me introduced to new techniques before I build my Opel Rak from Island models.
I thought the kit from Krick would have been a simple build.
Now after starting this build I can tell you it is not for the novice  :!:

When I opened the box I was abit taken back by the amount of wood.
It all looked daunting.
I studied the plans for a few hours then cleared the work bench and laid everything out and made a start.
I think this build may get the prize for the longest build on glider ireland history.

Why do I say it is not for a novice builder like me ?
Well  for starter the ply parts of the build are not pre cut !!!!!!!!!!!!!!!
They are marked on the ply by a knife/blade but I had to cut every ply part out by hand following the blade marks on the ply.
This takes quite sum time to do.
here is what I have achieved so far,

The main fus is almost finished,

Brass fittings have to be cut ,drilled and shaped.

Wing wire tension adjuster, pity it was not a brass bolt !

(http://www.gliderireland.net/forum/images/uploads/Richard%20Boyd/P1020598-1.JPG)

I have built everthing so far using white glue only
This sure is super slow to build with but I am praying well worth the wait.

Brass fitting for the elevator rudder wires

(http://www.gliderireland.net/forum/images/uploads/Richard%20Boyd/P1020602-1.JPG)

Center wing ribs,  as you can see the outer guide lines are easy enough to cut using the ban saw, but then when you have exact center holes to cut out it become a pain and time consuming.

(http://www.gliderireland.net/forum/images/uploads/Richard%20Boyd/P1020603-1.JPG)

Center panel dry fitted ! I have to return to the main fus at a later stage

One very very welcoming thing about the krick SG38 kit, the intructions so far are spot on  :)

Wow! Richards discovered a building material that's NOT foam!

Very nice Richard. You think the kits bad, imagine building the original! :?:

Post by: gerryb on August 11, 2011, 00:00:39 AM

welcome aboard rich. goes to show real aeromodellers/aeromodelling are very much alive!
i'd be a bit wary of using white glue on an open structure (pva, i asume?). to my knowledge it's not usually waterproof so i'd suggest you make sure it's well varnished when the model is finished.
hope you enjoy the build, gb

Thanks gentlemen for the kind comments.
This wood bashing as JP calls it is very addictive and seriously satisfying.

Hi Fred , yes I think this is the 1/5 scale SG38.

Hi Gerry , THANKS FOR THE POINTER ABOUT WHITE GLUE.
I never thought about the glue on an open frame, so now it will have to be well protected from water. A few coats of thinned varnish should protect the joints.

Tail boom got started yesterday,

Spuce top boom halves jointed for extra strength

Made a start on the rudder today, for such a small part there sure is alot of bit to cut out and glue together.

Richard,…….,
I know you, (and others) will tell me that I’m missing the point, but that looks like an awful lot of hard work for something with only limited flight performance. And one rough landing could ruin it. :!:

Good luck ol’ fruit.
(It’s certainly not something I’d want to take on.)

The structure/design of the SG38 seems to be very solid, I am learning how to land before I try to take off   :shock:
Is that Irish or what ?

Here is the real thing fly

Thanks Fred, things are going to slow up as I am away for a few days plus I have to make a new fus and center wing panel for an eliminator glider.

After mt L fly-in its time to get back to some building, elevator almost complete.
I am undecided of what way to hinge the elevator, maybe a fabric hinge would look more scale like than the hairy hinges provided in the kit,
What does the scale men think ?

hi rich, i recommend the robart 'hinge point system'. are you familiar with them?  they come in several sizes including 1/8" and 3/16" and use a metal rivet for the hinge.  i usually get mine from tower hobbies. fairly cheap and very easy to use.

nice work on the tailplane by the way.

forgot to say rich, they also do very nice scale type control horns and closed loop linkages. worth a look

Post by: gerryb on October 05, 2011, 21:57:08 PM

i'll eventually get it right rich, it's du-bro who do the closed loop fittings. they call it a pull-pull system. check out the kit for .40 to.91 size aircraft.

Thanks for the guidence .
I am along way off the hinge process but one needs to think ahead.
