Question

Are there any thermaling flying wings out there?


Anyone KNow of some good thermal flyign wings?

I'd like something to break up my huge polyhedral/conventional tail fleet.

Foam or balsa, big or HLG, kit or ARF, i'd just like something different.

Mini-reviews, pics or vids would be great too!

Thanks!

I just bought a Zagi THL off the "For Sale" Forums last week. It's a 48" lightweight wing that is advertised as a thermaler (is that a word? )
According to the instructions the the AUW should be around 11.5 oz's, mine ended up around 12.5 using HS-81's a 4 cell (AAA Flat pack) battery and a Berg 4L RX. They explain how it can be bungee launched in the instructions but I'm just going to be using it as a light lift slope flier.

Well I'm currently working on this:

http://www.glide.net.au/flyingwing/herks.htm

and will make the wings by this method:
http://www.mackrc.net/patternwings2/index.htm

But I've blown the model up to 100" wingspan and will build two fuselage pods that the wings will bolt to, one with an electric motor and 7 Cell pack and the other as pure glider. I'll also be adding a small a parachute to the aft end of the pod which will be deployed on short final.

A friend of mine had a German kit called the SB13, about 80" span that had the chute and it was cool to see it deploy on final approach.

Windlord


I have flown a Windlord for 25+ years and it could hang with Aqulias and Esprits. About 1200 squares at 100 inches. Check Ray Hays' web site for a picture and kit info, kitted by Ray. Plans are available, also. You will not be disapponted with it at a woodie TD contest.

Three flying wing HLGs that I know of are called: Aluah, Boomer, and Red Herring. You can find multiple threads on all three in the Hand Launch forum. All three are made of foam and I think all three are still being manufactured.

Ohio Pete,
They lie!! Use it as a sloper - in 20Kts+ put a slab of sheet lead over the CG and fly in in a gale

Zagis CAN soar!!


Sorry to disagree with a previous poster but the Zagi THL will thermal. Getting the tow hook in the right spot is a bit tricky and too much pull on the histart will cause the Zagi to flutter. Besides, the hook gives me something to hang on to when I do take it to the slope. It's not a floater and it's a bit of a challenge but it will hang in lift. For histart launches, I put a small area of sandpaper on both sides of the wing at the trailing edge. Hang on to this - then let 'er rip.

I used to hand launch a CO8, it was actually pretty decent. It doesnt thermal like a modern DLG, but was better than the skeeter I had.

A buddy of mine flew a Windfreak for a few years before semi retiring to raise a family. It was an excellent thermalling wing.

Suggestions for ZAGI THL


I have a ZAGI THL that I purchased years ago and never built becuase I lived in flatland and never was convinced it would thermal well emough to justify the work putting it togethor.

I have sinced moved to Co and am thinking about putting it togethor as a sloper. I was planning on buying a carbon rod and inserting at the cg point as a spar for strength. Any other suggestions? And does this sound like a good idea?

The Zagi THL flies great as-is. If you really pay attention to the weight thay can be built quite light. Use light servos, and a 270 or smaller battery pack, and try running your CG back around 8" from the nose, with really small elevator throws.

I used to combat the Zagi LE, which also had no spar system, and they actually held up well. And even they would thermal in very light air on the slope.
