The light conditions weren't ideal for the S.Junior's maiden, but flew she did, even if the landings were both hurried crosswind affairs...

At this size, it's a very handy model for those well-stricken in years... (This brings our fleet of electric Bergfalke 4's up to four)
Is the collective noun for them a "Stefan"? as in a group of Stefan E-BERGs :roll: :lol:

Hello,

New to the forum and this looked like the appropriate place to ask my question.

Just in the process of completing my first glider build in 30 years. Getting back into it and having much fun enjoying some much needed man meditation 🧘.

Not an exciting build by your standards being an Aeronaut laser cut RES 2 meter glider, but thought a good place to start.

Looking forwards I want to start my first scale vintage glider build in next couple months that will also be a bit of a trainer.

It needs to be a manageable size to start (3-4 meters) and a safe ‘easy’ flyer. Construction not that radical as still learning the ropes.

Any suggestions from the group?

All going well it will get a start in August and finish before before 2021 ends 😬.

Cheers from down under

Alex

Hello Alex

Welcome to the forum. There will be many suggestions for a first scale build.

Bearing in mind ease of construction I'd go for the Cliff Charlesworth ASK18. It's a great performer without too many curves to the fuselage and construction is very traditional. The only area of problem I have ever had with mine is the elevator linkage in the fuselage. If you follow the drawing with a simple clevis to the elevator horn you will find it's difficult to assemble at the field.

Better to use Chris Williams idea with a steel pin attached to the elevator and a sliding piece of brass in the fus with an appropriate sized hole in it.

Cliff Evans could help you with plans etc.

Hope this helps

Ian ;)

Thanks for the link Cliff

Wow to be honest I was surprised at the recommendation. I figured a boxy high wing trainer type like a Grunau Baby would come up.

To be honest I was a little scared of curves as a first project. You guys make it look easy.

Looking at the ASK 18 it’s a lovely looking model and I have been an admirer of Cliff Charlesworth. I’ll check the build threads to see who has made one.

Maybe I’ll just have to dive in and swim 😬

Thanks again 👍🏻

Cheers

Alex,
I cannot spot a Charlesworth 1/4 scale ASK18 build thread on the forum, but one has been built fairly recently by Brian Taylor (using the updated wing design mentioned below).
I’m sure that it would make a lovely build & there will always be help/input available on the forum.

As mentioned above, there is a new CAD derived wing design available for this model which utilises the HQ3.5 section, thereby eliminating the need for building in any washout as was standard with the original design.
The CAD design should also greatly ease the assembly, as things will notch together much better than with the original Cliff Charlesworth hand drawn plan. The wing ribs also have lower building tabs to allow the complete wing to be built up over a flat board, plus I think there is optional top surface wing bed to use whilst applying the lower skins if needed.

The fuselage is still the original design, so using more modern techniques in some areas would be worth considering - such as the elevator pushrod/connection mechanism as already mentioned by others.

Have a word with Cliff at Laser Cut Sailplanes for more info.

Peter
