Yep! I'll probably fibreglass the nose to compensate for the longer leverage factor. (Or get a proper CF boom, lol.)

It is not. It's an older style DLG that we were playing with. I learned that the launch settings/config can be very complicated if you want them to be.

It can be complicated. We were playing around with ail air brakes tied to the throttle input, switch activated launch elevator settings, and rudder ail mixing. This was the first DLG I've thrown so Eric was helping me learn the technique.

As for performance, if I can't get some good results then I may not even release the plans.

Wow, that's pretty good actually! If you can keep the AUW at 130g or less, I am telling you that it will float!

Man 130 wont be posable. He still has 4servo and linkages, rx, and a small battery to install i would say at a max min with a evry small battery 175g. But then i would say its to light and youll get no height. Most DlG are happy around 9-10oz

With electronics it's 180 g. I am using 9 g servos and a 350 mah 2s. And I actually need that amount to get the right CG. I think to build it lighter I have to bring the tail section in a bit or extend the nose.

Lol! You're spot on!

Your right, jayz. ~175g does sound more reasonable. *rueful expression*

Nic, I built a FB DLG two days ago, and I got it fairly light. The main problem I keep on running into is the foam getting soft on me. The wing tends to deteriorate within 70~80 launches. I can get a good 100ft of altitude, but even with the elevator at zero and no real vertical G-force (only horizontal G's) the wing will fold eventually. The only way I can see to get a FB DLG strong enough is to get 1mm by 5mm by 1000mm spring-steel flat stock, and glue it in the wing like you do with your nnMig-3, and your other speed planes.
This would not be the lightest way to do it I will grant you, but the alternative is a good CF/fiberglass job (which would cost more then I would like--or anyone else for that matter).

Oh, almost forgot: Another way of doing it is to use a 750mm x 5mm x 1mm piece of CF from HK in the wing. I have not tried that, but it would be much more effective (and ligheter) then the small hacksaw blade I have in my wing.

If the wing is too weak with the strapping then I will be trying a speedwing. It will add about 20g to the weight so it will be still be good. Maybe I'll increase the wing span a little to compinsate.

Why not consider a Carbon Fiber flat bar instead of the strapping as a spar the length of the wing and as an anchor point for the throwing blade? Something along the lines of this...

Might that help durability and longevity?
