Hi Yuri, You're a very good builder to create your glider with hand.

The failure rate of my hand cut wing core is just too high. In the long run, CNC foam cutter is a better investment for me.

And I don't have to inhale the fumes as much .......

Some more foam core cut .....

Wow, those are some thin wings! Have you said how you will construct them?

Looks like conventional tape/covering is not going to work for this thin MG06 airfoil.

Will be doing vacuum bagging EPP instead.

I was thinking about CF spar with 1.5oz FG. After cutting the wing, I think I need to beef up the layup a little bit. Especially for the front wing which also serves as landing gear.

May be adding more CF and additional Kevlar doubler 1 inch after LE, so I can have a soft LE (1.5 oz FG) and stiffer wing and aileron (1.5 oz FG+Kevlar). Let me know if you think this scheme will work or not. Thanks in advance.

Vacuum bagging EPP


BTW, here is an example of bagged EPP vertical tail with 1.5 oz FG and CF tow.

Almost as smooth as mylar, stiffer and still bounce back after compression.

Here is a technik I learned how to finish EPP fuses,You probably know it Yourself.
Sand as good as You can ,fill with Light Spackle putty/Home Depot/dry and sand again.Then spray 3M 77 light and cover with 3/4 oz cloth.
Soak this with Thin CA,/drops from a bottle/then dry,fine sand and paint.
I can finish a fuse in one hour from scratch.Quality is amaizing and smooth like molded .Does not gain any weight.Feels like an egg shell.
I did even a set of small wings once,but You have to be careful and secure wings before spreading CA as CA warps wing while drying.

Thanks for the info. I was scratching my head to decide if I want to bag the fuselage like the wing. Looks like I have an alternative.

I probably will do just like what you did except using epoxy instead of CA. Is that fuse for your scratch build Alula? Look very sweet.

Goede,just try a small piece of EPP foam with CA /on fresh air/.I bet You are going to love it better ,cause there in not as much weight as with resin and instant results./This is Quickie ,right ? /
No this fuse from Orbus I am finishing mold for Alulas fuse next week.Being working too much lately.
