Well drilled the holes for the wing incidence tubes. Then added all the rest of the rear ribs. This time to ensure things were better I carefully lined them up and if the rib was up or down then I adjusted the but join at the end of the rib by sanding. Hardly any need to add and remove bits of wing, result a much smoother wing.
So here is a pic of what I have done with the rear ribs added.

Next thing to do is tidy the ribs up so the wing surface will be smooth as can be. Then add the AB surround and the drag spar at the wing root.
Next evening spent a while making the surrounds for one wings air brakes. The surrounds are so the sheeting can be glued on and hopefully the airbrakes are flush with the wing and pop up neatly, well that is the theory. Other wing to be done tomorrow. Should be quicker as I have had to figure out out for the wing completed.
Mounting the servo is tricky may put the servo in front of the spar to give a little more room for the actuating mechanism and not fowling the servo.

Well, finished of the Airbrakes adding all the surround wood for gluing the 1/64 ply surround to. Added the servos and will add the linkage later when it is really cold I'll bring the wings inside and the RX and TX and set up the AB properley.
Also added the top and bottom drag spars. Need to add the ply webs, but need some ply for that.

 |
Well next jobs are get some 1/16 ply, and finish the drag spars. Then finish the wing tips as well.
Then wing will be ready for adding the 1/64 ply sheeting, of which I do not have enough!

Next the wing tips. They are 1/32 ply that goes into the leading edge spar and aileron spar. Balsa the fills the gaps.
It will be sanded to shape once the ply covering is on the LE and the LE is added as well.
Ready to install aileron servo mounts in wing. Mounted the closed loop horn and a push rod to the servo so that just needs the closed loop wire which will be much later. Mounted tow release servo as well.

I made a self locating elevator linkage and it worked, however it did not give me enough elevator movement. So lets put a servo in the tailplane and add a horn to the elevator. Wow!, wish I had done this earlier, slop free linkage and the movement required! All I need now is a plug and socket arrangement that is self connecting when the elevator is added. |

Also added the rudder and tow release servos, the pushrod is on the rudder servo and connects to the horn for the push pull cables
The horn is shown inset.

Made up a plug and socket for the elevator servo so it is self connecting when I mount the tailplane.
I had a 3 pin din plug and socket lying around. So mounted the socket on the near where the tailpalne captive nuts will be. It has the wires connected to it on the LHS. The plug is on the RHS and will be mounted in the tailplane once the tailplane is secured to the fuz. The expectation is is will make good contact when I screw down the bolts holding the tailplane on.
Also made a mount for the RX uing my standard method of velcro. It mounts the RX securely and IMHO on a sudden de acceleration the velcro will absorb a lot of the force and protect the reciever.
I used a snake inner as an arial tube. Take a few small scraps of ply and then drill a hole about the size of the arial tube. Put the scraps of balsa on the tube at each end and a 1/3 and 2/3 along as well. Route the tube where requird and then secure teh scrap ply with cyno to suitable points in the fuz. Hey presto! one arial tube secured.
