Over the years i've built several size Gyrocs. From the original to a 3X upscale.. but never had much luck with the things.
Seems no matter how lightly I built or got the fin tabs to work the helicopter recovery always landed with the Nose Stuck in the ground at least an 1" or so.
Not to bad in soft grass fields but hard packed summer fields did in most after just a couple flights.

Sometime mid 80's someone suggested perhaps adding a 3rd fin "might" help lower the recovery speed. A couple tries later mine still don't recovery all that softly but at least doesn't crimp the tube so badly.
thought I'd try a Micro version to see if that would be soft enough to bring the Gyroc down without sticking staight up in the grass or ground.
NOPE! even this TINY 4.2gram T2+ size model comes in pretty fast and sticks stright up in the grass or ground. Spins really well but I guess it's something I'm doing? A fun flyer anyway.

This Gyroc is an up scale to BT 55, hand turned nose cone, rear ejection motor mount and uses brass hinges in place of the traditional vinyl type. The flap retainers are mounted on the motor mount which also sports an 8'x 2" streamer. Not much is traditional here except for the basic design. Even the paint job spells Rock-n-Roll.

Nice build there, Gary. That paint job would not have been my first thought—I like it. Well done.

I know you mentioned it's a BT-55. What are it's dimensions? It's hard to get a sense of the upscale with that Centerfold shot. Again, nice work.

Let us know how she flies when you have an opportunity—if you would, please. Cheers!

Thanks man. It measures 17" tall and has a 10" fin span.

Ditto, Gary. I'm especially interested in how well those "flap retainers" work out.

As you already know, I tested them yesterday by hooking up the tension bands and physically pulling the motor mount out and the flaps worked perfectly. The retainers appear to be doing their job and it took very little effort to remove the motor mount. This is one I could possibly take down to the ball field and launch it with a B motor just to see how it operates on it's own.

Back when I started building Estes rockets, mid '60s, the Gyroc was always given to you as a free bonus kit whenever you ordered the kit you really wanted. I always suspected the Gyroc was a dud of a seller so Estes "generously" gave them away to get rid of their stock. Given the stories here of its lack of success confirms my suspicions.

P.S. After looking at the design and the complexities of the elastic threads and the folding wings, I never even gave it a try. Out into the trash they always went.

I had two or three free kits that I built and launched. The first two flew off at a 45 deg. angle right after they left the launch rod. Both lost in the forest of trees next to the schoolyard. Third one flew straighter, and was recovered. I painted an orange and white "barber shop pole" pattern on it to see it rotating down. Very cool.
P.S. See how much your "free" kit is going for now on eBay:

Ahh, if only my modelling skills had been not so limited. And my closet full of stuff, bigger. Wish I'd have kept my Camroc as well...

Heck, the recently-released Tazz should be included in this gallery.IMG_2418.JPG IMG_2401 2.jpg IMG_2440_V2F_2020-02-09_12-51-44_023 2.PNG

I loved the Gyroc—really simple to prep (just put the motor in) and nice slow descent. It was a challenge to get everything straight and flat enough to get a straight boost, but not impossible.

This particular Tazz works really well.

Heck---the Tazz IS a Gyroc from the fin line on down!! (Still don't think I want to tackle it...)

...well, it's actually an upscale. The Gyroc was BT-20-based. The Tazz is BT-50. The Gyroc repro that Semroc/eRockets is selling now (see GlenP's posts above) is the original size or very close to it. It, like the Tazz, rear-ejects a motor pod with its own streamer. To do that the Semroc one now uses 13mm motors rather than the original Gyroc's 18mm (which the Tazz uses).

The Tazz addresses the weak points of the original Gyroc in using a different, likely more durable hinge material (on both sides of the joint, not just one), and small, replaceable rubber bands going to plastic hooks in place of the original elastic thread of the Gyroc.

The Semroc Gyroc also tries to address these points by using Tyvek for the hinge and an arrangement for replaceable rubber bands as well.
