Alex,
I cannot spot a Charlesworth 1/4 scale ASK18 build thread on the forum, but I do know that one has been built fairly recently (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.

Thanks Peter for the interest and advice. The model does look like a nice challenge and performer by all accounts.
Continuing my quest to look back into the past through the wrong end of a telescope, the Rhonadler is now getting the scaling down treatment...This time to 1:3.9
