Working on wing set #3 and fuse like #6 or something stupid like that. Been much work, design and building, to get the weight and strength balance figured out. This plane will see air time!!!

Troy, I'll be setting on your doorstep when you get back in town.

Sounds good Sam. I should finally be back home Thursday. 5 weeks away from home is too much.

The clear wing tube is really a plastic guide tube for the wing tube. Good eye.

Gonna add some carbon to the ailerons too. Torsional strength, well I expected more, even with a conventional build they would wash out too much for me...

Needs cross bracing in ailerons and sheer webbing between spars.

Why plastic though? Isn't it heavier than phenolic?

it was reasonably priced and .002" larger ID than the tubes OD
I don't have a great source for wing tubes yet... if you have a good source send it my way!

An airfoil (instead of a flat plate) stab? Rudder and fin too?

That would be saaaaweet.

Cut the fuselage thickness in half, use some shockies on the sides for lateral stability.

Rudder is still up in the air.

Stab n Vader are in the pics.

So far I'm up to 312ft of cutting.

Parts list is close to done, gonna do another build to souble check the pile of parts.

Thinking rudder will be stick for the stab and stick/ply tapering for the control surface. How airfioled it will be would then be on the builder.

took a couple random other pics to show how this week has been going. the fuse shown clamped half off the table came in at 13.5oz.

Sorry, missed this one, top pic shows a more finished product. Several of the first parts made it to about 80% and hit the pile, including the one in the first pics.

There is a pic with a pile of scrap, somewhere at the bottom are a couple ailerons. I built both ways, and both sucked with the twist test. I am adding some carbon behind the hinge strip, bracing will be added after servo position gets nailed down.
Right now the second (outboard- not shown in first pics) servo tray is gonna go away. Still lots of work to do on the control surfaces, Troy mentioned I need to add plenty of structure for a tail wheel, need to finalize wind retention, etc...

Getting closer though!!!

You should cover it before the twist test, there's a lot of strength in the skin.

but strength before skin means a stronger wing than normal right?

Following this logic will end up in a fat bird. Do as little as you can get away with.
