Great thread. I used to fly gas bags and this thread prompted me to make my first post. Thanks. I love looking at bent wings.

"Gas bags" are/were the very lightly loaded, thick-airfoiled sailplanes typical of the early '90's and before. They are noted for being able to thermal like a dandelion seed (or a helium balloon, hence the name "gasbag floater", or "gasbag"), but also having the penetration of a dandelion seed.

When Joe and I first started working on what would become our "Monarch" RCHLG (the direct ancestor of our "Chrysalis" series kits), back in 1992, our design goal was to show that you could have a model that could float as well as a "gasbag", but still range and penetrate. Most folks would agree that we succeeded. Contrary to what was the accepted "common knowledge" back then, you do not have to give up low speed performance to get good high speed performance.

Hi Guys,
OK I'll throw in my best floater. This plane started out as an EZ 400 G. I then stretched the wing out an additional 2 ft. It's a flat bottom airfoil. I then got a bigger, longer C/F fuse and mounted the original tail on it. The end result, was the floatiest, slowest flying plane I have ever flown or seen fly. But, I don't see any other planes fly usually. That's because I'm the Lone Blue Plaid Flyer in Seattle. Here are some shots of it flying last month or so. This thing is so relaxing to fly, I can hardly believe it.

Like that Micropro radio!
Nice to see good radios still in service!

I have one myself, best radio I have ever owned!

Here's a couple of mine. A modified Sig Riser 100,that I built a Pod and Boom for and stretched the wing to 112". It is a real Gasbag.

And of course my Oly III. I love it. I have a couple more,but these are my two favorites.

On the building board will be my modified Mirage 5 panel wing.

Viking - Maiden report

Greetings all;
So the rain gods were kind to me today allowing me to get a few flights in on my Viking. Weather was not the best for the first time out but not enough to keep me on the ground. Skies were overcast and winds were out of the west, south west at around 5 mph with gusts up to 10-15 mph. First hand toss I found the CG was close enough. Second hand toss I saw a nice shallow decent, straight as an arrow. Time to launch this bird!!!!

I stretch out the hi-start and up it goes. I needed very little rudder stick since I was a bit cross-wind. First flight was to dial in the ship. I found I needed a very little up-elevator and all was well.

Second launch was better than the first. This time I tried a shallow dive to see the reaction of the ship. I was exactly on the designated CG as per plans, 3.5" back from the leading edge. One thing I notice right a way was it is easy to over speed this plane, causing the wings to flutter. Not good! I was lucky that things held together and there was no damage done.

Third flight I had added about 3/4 oz to the tail boom bringing the CG back about 3/8" back or so. I had a much better responding ship and was able to hook some lift. Nothing great with the lift. I was more focused on dialing in the ship as well as understanding how it responds.

The remainder of the day was to learn all I could with the ship. My findings;

1) This is by far a light air ship. The flat bottom airfoil on the MK I series is really not cut out for high performance.
2) I can have a lot of fun with this plane even off a hi-start. I can see myself getting many hours of relaxing flying.
3) My overall impression on a scale from 1-10 is about a 7. I really wish I had the MK II wing/airfoils thinking it would have better "legs" especially in a breeze.
4) It is a keeper. I just love the way it looks in the air. The color scheme works great against white, grey or blue skies.

Hope you enjoyed the pictures.

Now onto my next bent-wing project.... to finish my 2m Miles

Love the plane! And that name, Womack, catches my ear.. there is an older amazing fella that flys at our little field with the last name Womack.. Francis is his first name.. he's a doctor AF divinity.. I wonder if there is any connection.. I think he has a house in Florida and some here.. hmm

Sorry bout the OT! Just thought that was interesting

Look for posts by shrederman. That's Jack.

And a pic of his prototype, the first Houston Hawk.

this was November, 2003.
