I placed the tube into the wing then I put the wing in its place in the fuselage, I marked a hole from the inside of the fuselage and I drilled a pilot hole, this gave me a starting point to drill the rib on the wing.
By cutting into the wing at the edge just before the end rib, I did a small hole just to get the blind nut through, by having the pilot hole predrilled I can now drilled a 5mil hole, and then it was just a case of gluing the blind nut through the 5mil hole.
I then placed the wing back to the fuselage and tested the fitting, A.OK. After the testing I placed at the underside of the fuselage balsa strips, So when I start with the covering of the model I can leave this slots uncovered to access the M5 screws.
Then I went and epoxy all the inside off the engine box, the outside with 30 Min Z-Epoxy. I added to the outside of the engine box a good amount off the 30min all around the surfaces.
After all the epoxy has been dried, I covered the model and sprayed all with fuel proof Paint to finish off the work. Then it’s just a mutter to start putting all the firewall components back together. Engine exhaust and CDI
I made two pieces out of light ply to the same shape of the aerofoil of the top wing.
After marking out the templates i then went and dry fitted the ply to the two wings. Then I drilled the two ply with a M5 drill bit, this will be more than sufficient to hold the two Wing together.
I placed the two pieces of ply together to and added a spacer of 5mil to compensate for the aluminium bracket, by mixing some 5 Mini epoxy I added the glue to the two wings and the ply, then I carefully placed the two pieces of ply to each end of the wings with the aluminium tube and bracket. After the epoxy was completely dry I then drilled three holes of M2, then I added pins to strengthen the ply to the wing rib don’t think It needs it just in case. I am more than satisfied with this job.
