essentially 1.5m x1.0m - maybe out of one sheet of FB!

@flyboa - sorry I made this demo piece in hast and over sanded the areas marked with the circles - my sample piece was too small and kept moving - as you know it is easier with the actual wing blanks!

So for sanding, the aim is to sand the top and bottom tapers identically (in my sample I sanded one piece then slit it in half) - I left 10mm of paper at the CG point 1/3 of wing size) to act as a guide for sanding - when glued face to face with the bottom flat on the table the aerofoil is formed - then we add the front caps for sanding the LE to your taste - I finished by cutting in the aileron (flyboa makes his aileron separately I think)?

It is a good system - just sand with care - take your time - I use Gorilla glue between the halves - tape is optional!

I couldn't help myself and set the 3D printer working on the DLGv2 parts over the weekend - hopefully they will print flawlessly and I can make the main wing next week!

So for the main wing, will there be a spar or something in there for strength or just straight FB ? What about the dihedral and joining the 2 wing sections?

@Wildthing - just foam - flyboa does not even tape the card, but I usually do because of the moisture here - the wings are remarkably strong - delicate in the grand scheme of things, but strong enough for this - you glue in fibre tape at the throw peg - the dihedral is also glued with gorilla glue and taped on the surface - in my ship the wing is glued to the fuse with hot glue - the fuse has about a 100x30 glue surface with the dihedral built in.

And in my mind I would tear it apart in one secondf with a quick loop or something and of course build it way stronger and of course be way heavier :D :D . Guys like @quorneg can build using candy floss and carry 50lbs of weight, not me :D :D

@Wildthing and @buzzbomb - I got the iron out at last - a real iron for shirts and pants - I used templates, a1mm wire at the bottom edge and a ruler for the top edge - I was hoping that would give me some accuracy!

Worked well - heat setting was ‘cotton’ and it formed in seconds!

This was another speed build test and the paper sticks well after ironing, so it is conceivable to laminate the halves with no paper removed.

I added the foam cap and sanded the leading edge and cut in the aileron - it was a bit rushed but I can see the benefit of no sanding - to make a wing, I should imagine the templates are a must otherwise over 750mm the compression will be very inconsistent!

Next time I would use a 0.8 wire for the TE thickness

Sweet,

I worked on the baron plans lastnight, not only the wing but horizontal and vertical will be done this way. This way I can also judge if there is any improvement on handling and speed.
