Hello,
Lawrence Prest here.Finally remembered my user name and password. Last year I built the ASK 18 from the Jilles Smits plan and short kit cut by a local supplier here in Queensland and having got it flying nicely,( we can only aerotow here in Townsville, no slopes for miles around), I mentioned to Jilles that I was on the look out for another build for this year and he mentioned that he had just finished the plans for the Pws101. I checked it out on the web and ordered a short kit.
What you see in the photos is the fuselage dry fitted together but the tail feathers are glued and will be finished up to the covering stage before proceeding too far with the fuselage.

Some more pics of the build from down under!
The tail feathers are coming together nicely. Once these are ready for covering I will move forward with the fuselage.

Wing joiner tubes have now been sorted out and fitted so now fuselage can be prepared for sheeting. Stringers being fitted, Elevator pushrod is now sorted. Tow release is next in line. Wing tubes are 3/4 inch aircraft alloy tubing which will have a hardwood dowel made and glued in full length of the tube. Nose cone is 3D printed and after the tow release tube is fitted and fixed through the cone it will be removed off the fuselage and filled with lead. So far so good. All parts going together very nicely.

Here are some more photos of progress. Elevator servo and pushrod is all sorted. 60mm of travel up and down as shown in photos. Tow release is all fitted up and a brass tube fitted through nose cone which is now filled with lead and weighs 572 grams and still needs filling with epoxy resin. also made a ballast box which will be glassed inside and out and will hopefully carry at least a kilo of lead. With these little jobs out of the way i can now finish preparing the fuselage for sheeting, with 3mm balsa at least down to the bottom stringer.

Cracking on with the sheeting now. The large flatter area's will be covered with fitted sheeting and the more curvier area's will get fitted planks.
I will fit as much as i can while its on the board. Thoughts are already turning towards the wings. I will have to make my building board about a metre longer i think. Really enjoying this build and the challenges it brings up.

Top sheeting is now all fitted down to the bottom stringer. I dont think the fuselage will change shape now so it will be safe to remove it from the building board. Bottom of fuselage will now be prepared for planking. Once the fuse is ready for glassing i will put it aside and make a start on the wings. Happy days......

This build looks very good.
I'm not so sure I would use the plastic push rod for the elevator. They are not very positive. You might find that you have false centering. They also have issues with changing centre as the temperature changes.
