Speaking of Stine's original Flat Cat design, I bought and built one way back in my early years in the hobby and had no problems getting it to boost and glide properly. Before that I
think my only other B/G experience was the Estes Astron Space Plane (loved the kit and build, but the first flight the ejection of the engine ripped the elevon tabs). Then I built one
called the Raven from plans (think it was in the Estes Model Rocket News) and started ordering the B/G and R/G's from CMR (Manta, Orbitron, and Buzzard), which I still have (and
use in competition) today ! I've built an upscaled version of the Buzzard for use with
18 mm engines (I think Gassaway gave me the plans for those back in the 1970's, and, yes
I still use that upscaled Buzzard today) as well as the Nymph slide pod R/G (13 mm). Boost
and rocket gliders are a lot of fun!!

The Raven is GREAT!

I won an A BG contest in Michigan with one once.

Ok, so what if it was on a postage stamp sized field. . .

I'm bumping this old thread because it came up in a Google search for the Nymph. I have a copy of the plan that used to be on the NAR site, but what the plan doesn't show and what I can't figure out is how the burn string is rigged. There's nothing forward of the pod, so how do you rig the string to pull the pod forward?

If I get the chance, I'll try to see if I can find my Nymph R/G (assuming I still have it in my stash somewhere), but I do recall the slide pod was held in place by a thread (had to use a needle to "tie" the thread to keep the slide pod in launch position), then right before launch the rubber band or elastic band was stretched into place that will pull the slide pod in correct position after the ejection charge burns the thread. The model is very reliable.

To hold the pod forward the string goes right through both tubes just forward of the motor. Use a needle and thread, and just poke a hole right through the pod while holding the pod in the forward position. Secure the two ends of the thread somewhere on the pod stand off out of the way of motor exhaust. It's a little tedious. There is going to be a lot of pressure placed on the thread from the rubber band that's pulling the pod back. You can double up on the thread. That's how I remember doing it.

Wow, this thread seems to be as immortal as a unicorn! Speaking of basic R/Gs for beginners, a slide-pod R/G (in versions sized for 13 mm, 18 mm, and even 6 mm [MicroMaxx] motors) with a delta wing and a forward canard (like the Centuri Mini-Dactyl's two gliders, see: http://www.ninfinger.org/rockets/no...a/73cen00c.html ) would be a great plan that the NAR could have on their website. The Mini-Dactyl B/G's two gliders are very easy to build and to trim for a good glide (and they're good "foul weather" gliders, having good wind penetration), plus they look sleek. A slide-pod R/G version, up-scaled slightly to compensate for the mass of the motor pod and its expended motor inside, would be a virtually foolproof "first rocket glider."

I found a few pics of my Nymph R/G from an album in my files from a Regional Meet at JSC in 2007. Here's some pics:

Hmm. JimZ has a page for the Mini-Dactyl http://www.spacemodeling.org/jimz/km-6.htm but the image links are dead. Internet Archive doesn't seem to have them either.

I found this page http://naramlive.com/archive/Naram%...ocket_glide.htm which has this graphic http://naramlive.com/archive/Naram%...lidePodprep.gif showing how slide pods are rigged. Why they didn't show the burn string hole on the Nymph plans I don't know. It would have made things a lot clearer.
