George,

Did you ever pursue that folding conventional glider design further or abandon it, due to the FAI rule change ?

George,

I saw and read the thread at that link.

I guess my question should have been " did you ever expand the design into using vacuum-bagged foam wings and control surfaces, for even more weight reduction" ?

Frankly, your folding glider designs are fascinating, George !

Have you ever considered an RC version ?

Dave F.

With the previous mention of the R/C Astron SpacePlanes, here is a link to my website, with some info and pics about the 2X and 4X versions.
http://georgesrockets.com/GRP/GLIDE...Spaceplane.html

Pic of the 2X (35mm Quest tube), and 4X (BT-80) versions.


Pic with Vern (He is holding a Golden Scout)



If you look close, you can see the joint where the BT-80 separated for transport along with a bit of the forward part of the wing. Shipped in a cardboard box.

And I recently found this video of the 4X flying at NARAM in 2008, so posted it on Youtube:

George,

With all of the knowledge and experience you have, you should write a book . . . Seriously !

It would be a great resource for Rocketeers and a "legacy" for future generations to use and enjoy !

Go to the 2nd post here < https://forums.rocketshoppe.com/sho...ght=flying+jake > for 'Bumble Bee' launch and glide pics. Not sure what the current record is for 1/2A boost Glide Duration, but this one was still rising on a thermal and disappeared after at least 15 minutes.



I've since built 3 of the Bumble Bees, but haven't flown them yet.
The CMR Stingray is finished, but has yet to be flown. The CMR Buzzard still needs a few finishing touches, and the Geoff Landis Goose III is still in a shoe box.

The GOOSE III image won't enlarge.

In addition to the GOOSE III, Geoff Landis also designed the GOSLING.


Did you make any patterns of it ?

I just added a new photo of the Goose III parts. I did make patterns for both the Goose III and Gosling, but cant seem to find them right now. On a side note, the Gosling plans do not include a pattern for the rudder. I was just going to - wait for it - 'wing it' when I get around to building one by enlarging the drawing in the plans.


I did build a Goose III years ago (1998?) and flew it at a CMASS launch. At about 50' up, the back of the canard broke off - I may have put too much camber in it - but at pod separation it transitioned into a beautiful flat glide. The wind carried it into some tall grass and I never recovered it, but it really is a nice glider.

Well, I guess what is "good for the Goose is good for the Gander" . . . LOL !

I suspect that "flutter" might have been a possible cause for the Canard failure . . . Thoughts ?
