Hi!

I only had a dream of building DLG as a kid. I had many failures on the road, but if you're stubborn enough you'll make it right eventually. This is my first DLG that is flying and completely built by me from "tip to toe".

This would be impossible without big help of my dear friend Yasuhiro Ueno! His help was beyond measure! Thank you again Yasu!!!

I was inspired by Mr.Yasuhiro Ueno and Mr.Mitsuru Ishii so I named glider after them, YaShii!

Control is by elevator and rudder. RTF weight is 59.4g.
Air time in still air around 50-60sec.

Beautiful work

Thank you!

Nice! How did you sand the airfoil?

Seems to fly really well. Nice.

I followed Yasu instructions on one of his posts on 600mm dlg.
- I used #100 sand paper to form rough airfoil
- First I did leading and trailing edge then top surface and last bottom camber
- Finished with #300,#600,#1200
- sprayed 2-3 thin coat of clear acrylic spray
- polished with #2000 sanding paper


Regards
Ivan

Very nice work.
I'm wondering if maybe you could go with an integrated receiver/servo board like the E-Flite to save even more weight. See link for example:

You can get find these linear servos separately without the integrated receiver and ESC as well.

Hi,

Thanks!

I could but it is not necessary on this span, because CG is just right with this equipment, I didn't put any ballast.
On smaller span it would be necessary to put lighter gear similar you mentioned.

Regards

More beautiful work Ivan- I'm impressed.

You have one final secret to reveal: how you make your pods. You told me in another thread that you use shrink tube, and I'm wondering if you would be willing to share information on the details of your process for making a pod?

Thank you

Wing is bit heavier from the first model and with different airfoil.
I tested wing on fuselage from first one, but we need to see how it will fly with this new one.
Length is 640mm, expected RTF weight is about 70g.
Wing weight ~37g
Hopefully tomorrow it will be complete and in the air if everything goes according to plan .

It's in the air

76g RTF weight
