Thanks Adam !!

You know that`s really funny -because i didn`t get the plans from ryan's i searched for other plans and finally found your thread -so i am already building your wunderful plan but also wanted to ask if meanwhile someone got the plans from ryan's ^^

so ,to make it short -i am already building on your plan since 2 days and know already finished one half of the wing=)

btw:- did you just shape the wing, and then glue it on the boom or do you also have any reinforcments(tape,cfk rod ,etc)?

I will add a cfk stab in both of the wings and then i will add rovings like ryan did and finally i will add some tape to the leading edge..

will add photos later on =)

regards
Markus

This micro DLG is based on the Quark by Adam Woodworth, i have simply modified it a bit so thank him for the concept.

that looks like a cool kit, i'll post a link to the site: http://www.skyhighhobby.com/micro-d-...lg-glider.html
is the black on the wings carbon or just for color?

Pretty slick looking. Bagging the wings or a simple coat of clear would help smooth out the airfoil surface - every little bit helps!

I've slowly been tinkering with a new 24" span HLG, got the wing and tail done, gotta find an appropriate boom and figure out how to stuff 4 servos, RX and lipo into a tiny fuse pod. Sticking the aileron/flap servos in the wings would be much easier, but I'd like to be able to swap different wings.

Wow, Guys I have been looking at doing something like this for a long time and I just found this tread and now I am pumped. Can't wait to get started with one of these little HLGs. I have been doing FF HLG for a long time and Micro R/C version is just what I wanted. Keep up the great work. mirco_builder what thickness of balsa wood did you use for your wing?

Has this thread been moved? I haven't seen it before. (It refers to "looking in the Micro and Indoor section...")

Very nice stuff, in any case. Some more info on the construction techniques used to build the Xelion would be welcome.

I think it was only 1/8" balsa, so it didnt have a very thick airfoil. Guess that would be better for higher launches, but probably suffers a bit in lift. That is why I'll be going with flaps on this new one, high launches and good lift, best of both worlds (not to mention cool looking micro air brakes )

Nope, always been in this forum. Its already a 3 year old thread though, so it got pushed way back. Lots of good stuff though!

I'm interested in the use of CF on very thin wings. I've seen some very usable wings cut out of Blucor, but they seem to be a bit...crunchy...without reinforcement. I've seen the helix pattern on larger gliders - I presume it improves torsional rigidity?

By helix do you mean the criss cross pattern? If so, then yeah its for extra rigidity with minimal weight gain - the inbetween of having none or little CF for lightweight and full carbon for strength. I'd like to give this stuff a try. Also wish I had the skills to make a molded wing...

Also, I didn't see in the forum the technique that you used to make your nose pod. Do you have a link to a guide? I am buying some of the basic stuff tomarrow. I can't wait to get started. Also, how are you attaching the wing? with two small carbon rods attached to the wing and feed into a balsa block in the pod? If that is the case how are you securing the TE of the wing? Thanks in advance.

I didnt take any pics or anything during the pod making. Pretty straight forward though, carved and sanded a balsa block into the size/shape I wanted, pushed it into some clay and let it harden over night.
Next day, popped out the balsa block from the clay, sprayed the clay mold with spray adhesive and laid down saran wrap material (could've also sealed the clay with paint, then used a mold release agent). Used spay adhesive on the balsa block and covered it too with saran wrap.
Mixed some 30 minute epoxy and spread it over the kevlar cloth, then laid the wetted cloth on the balsa plug. Used a paper towel to soak up excess epoxy from the kevlar, then inserted the balsa plug/wetted kevlar into the clay mold.
Clamped the balsa plug and clay mold together and let it cure over night, popped it out the next day, peeled back the saran wrap, and whamo, a nice little fuselage pod It did take me 3 tries to finally get it right, there's some trial and error in the amount of epoxy to use.

I did as you described for attaching the wing, two spars in the leading edge of the wing, inserted into hardened balsa in the fuselage pod. Trailing edge had a piece of CF glued down the root of the wing, sticking out past the trailing edge about an inch or so. Used a piece of heat shrink tubing to secure that CF to the boom. There's a picture of the setup here in post #52. It worked ok, but the harder I threw the plane, the less I trusted it. Ended up just gluing the wing down. Still have to figure out a way to make it nice and secure, but removable.
