Some progress....I can report today that the T/E flap and aileron hinge support blocks have now been fitted.
Also the lower wing skin holes for the servo access have been cut out.
I have made plywood servo support plates that will allow the fitment of the wing servos and associated access plates. Yes, I do appreciate that this may be slightly over engineered. I have also made the component parts for the external wing tank release system and associated hard points where the pylon will insert into the lower wing skin.
The servo for the tank release system has its support structure made, now awaiting securing.
I have now installed the wiring for the wing navigation lights and the servo extension leads through the straws.
Many thanks to Martin for e-mailing me the under wing tank drawing. I have cut out all ply parts by hand using a coping saw and a file. With hindsight maybe having a lazer cutter available would have been ideal. I have now only dry fitted the 6 tank formers to the keel section and some more adjustments are required to get the alignment correct before applying the glue.
I have now obtained some push rods that will be the main component of the under wing tank release system. I will also be using a single servo to operate the mechanism.
Further progress has been made in the form of the fitment of the clear straws to allow the wires for the navigation lights to be run along the wing. Also the top spars have now been fitted.

Martin, PM sent.
Many thanks Tony.
Thanks guys for all the advice regarding the fuel tanks. I will wait for the PDF in due course. Cheers Tony.
I too would be very interested in a PDF copy so as to build some external fuel tanks. Currently looking at the options of constructing the release system.

The wing build continues with the installation of the modified wing ribs that allow straws/tubes to slide through the enlarged hole in the rib, thus allowing me to thread the wiring through for the wing nav lights and servo leads.
Also, the top wing spars have been fitted. I have also obtained some lead weights so I do not have to use soup cans anymore. The next part of the build will be the fitment of vertical shear webs and the false T/E & L/E strips. Will also have to think about servo selection and how to mount them in the wings. May also think about adding hard points in the wing for the possible addition of external wing tanks in the future.
Today, I added 1/16 x 1/4 balsa strips to the top of the lower wing spars and intend to do the same with the top spars. Only a minor hitch which was easily rectified. Looking forward to the next stage of the wing build.
More work carried out over the weekend. Installed the lower wing spars on both wings as indicated on the drawing as 1/8 x 1/4 spruce or hard balsa and this item was also listed on the original additional wood pack list. Only to find when dry fitting the wing ribs that the spars are far to small. Should be 3/16 x 1/4, as listed in the updated wood pack list. My work around is by adding balsa strips onto the top of the 2 lower spars before installing the ribs.
Chris, just stocking up for Christmas or maybe needed after Brexit.
Lower wing skin panels marked out for position of wing spars and ribs. Notice the use of tins of soup and beans.
All 4 panels complete.
Photographs of the 4 wing skin panels.
Chris, many thanks for your advice and insight into the use of LED lights. As an inexperienced first time builder I will stick with the contents of the standard kit at this time as I do not yet have the knowledge to add/mix other electrical components but I will keep your suggestion in mind for the next build project. Also, I have decided to assemble all 4 wing skins before the wing jig is placed on the building board. I have ensured that I have allowed some extra width for the curvature of the wing ribs. Photograph to follow later. Advice from Martin Gay regarding "Straws" for the servo wires has resulted in the purchase of some jumbo straws from a well known internet site that has an internal diameter of 10mm which will allow both the wires and connectors to pass through them without the need to dis-assemble and re-solder.
Next step is to build the wings. Has anybody thought about fitting navigation lights into the wing build?
The wing jig now complete and ready for the next phase of the build.
