Hello Stuart,
Nice to see someone is observant. Way down the back of the fuselage there is a 2.5mm od brass tube fitted each to guide the pull, pull wires for the rudder. The red snake tubes you can see in the photos are only temporary. They fit over the ends of the brass tubes and run all the way to the rudder servo space and will guide the rudder wires through the fuselage so they dont take any wrong turns as i feed them in from the back end. After the wires are in place the red snakes will be pulled out. Fuselage is all sheeted now so i will post some more photos sonn.
Lawrie.

Hi all, here are some more photos. The fuselage is now all sheeted and planked. There is a little bit of filling to do and then some sanding. Anybody here enjoy sanding.......
Now its on to the wings. As designed, each wing panel is 2.6 mtrs long which is a bit to big for me to transport and not to easy to store away, so after a lot of thought and a few emails to Jilles i have decided to join the wings just outboard of the gull section just where the ailerons start. It makes for a bit more work and a bit more weight but for me it will be worth it in the long run. The timber stringers you can see on the bench are of Hoop Pine which is a local timber to Queensland with very similar qualities to spruce. The are full length, 12mm * 6mm and taper from the clamp you can see down to 3mm at the tip. I also pre bend them by soaking over night and bending into a jig and left to dry for a few days. While this was happening i was busy pre fitting the ribs to the ply spars, some were a bit tight, and also the front ply spar needed chamfering to match the contour of the ribs.The ply spars have build tabs on them to stand up on so i spent quite some time making sure the bench was nice and straight and no twists.
Once that was done i could then start to dry fit the ribs to spars standing things up as i worked along the wing, which is as you see it now. The whole structure just sitting there on the bench. I will now fit jig supports to the build tabs to hold everything straight. Each rib can the pulled of in turn and glue applied where needed and slipped back into place. Sheeting the top and bottom of the wing back to the main spar will be an interesting exercise.
Lawrie.

The left hand wing continues to come together. Top timber spar, trailling edge and leading edge are all glued up and work started on the air brakes.
Fitting all those balsa blocks at the leading edge took some but i think is a good way to end up with an accurate profile for the airfoil shape.
When i built the Ask 18 last year it has one long piece of balsa shaped to profile and even though i made a couple of templates to get the shape it left me wondering if i did'nt get the radius correct all the way along the leading, what effect would it have on the rest of the airfoil shape????

This week has seen me preparing the top of wing for sheeting with .4mm ply, and then the last couple of days fitting and glueing the sheeting into place. This morning i put the saw through the spars to separate the two halves, and now it will be on with the incidence pins and preparation of the bottom of wings for sheeting.

Hello from down under,
Some more progress at last. I have been busy doing other things,(I had forgotten there are other things in life apart from building scale gliders, B****r).
Anyway, I have made and fitted the wiring looms in each wing panel and checked and double checked the servos working about a dozen times so all is good there which has enabled me to finalize the joining of the wing panels. Air brakes are going together and this afternoon I got the aileron pieces out of storage and on to the bench.

Thanks Cliff.
Definitely a labour of love is this one, and looking forward to seeing it finished and flying.How is the canopy going. Im still some way off needing it, but if it was here i would be taking time out to admire it and it would inspire me to make the canopy frame.
Cheers.
