Nah - never a whole square metre. But it pushes the material cost of a DLG wing up to about 4 times what I am used to.

Not much progress....

She's had her final sanding and a first light layer of 50g glass applied with 3M77 and wet out.

After a discussion with Graham, we have decided to build the wings in two parts with a wing joiner.
He's pretty confident that the weight can still be kept to a minimum!
Actually, I'm pretty relieved as I can dump the "Dorsal Fin" idea.
I like the the current clean shape and the wing joiner tube will brace the mid section anyway.
There won't be any cast-in fillets so that we can experiment with wing position and balance....

Just a idea

How is your wing analysis going Graham?

Nice progress Johann.

How many layers of cloth do you use for the plug? and is that balsa?

Yeah, It's a balsa plug with a glass stringer...
Previously I used foam, but with a thin slender thingy, it needs some strength to avoid warping and bending!
I'll still apply two layers of 100g cloth.
The Frecote releases well, so it should be thick/strong enough not to damage
We'll see

Errr.... it's pretty cloudy most of time ( crystal ball ),

Still looking into sources of wheels for the fin , at the moment I have a spare one, on its very own axle attached to a wheel barrow.

The plug is looking good J.

Yip, these skinny fuselages are difficult to keep straight. For my Quirk I used a 6mm mdf stringer with 160gsm glass on each side, then I laminated foam on each side and shaped. I like your balsa idea since it's easier to shape.

Not shaping another fuse this year, I already have 2 shaped and ready to mould.
