Yes I did.

Here is a YouTube video of it on an L motor

It's 36 inches in diameter.

This is the 75 mm Cinco. It flew well on a K motor but tumbled during recovery and landed on one of the corners.

Cool videos. The Cinco seems to be a lot more stable in flight that more conventional rocket. There is much less spinning going on during the ascent and it stays fairly level during the descent...
The problem is not the going up. It's coming down. Larger motors are heavier even after the propellant is gone because they require longer (heavier) casings. Rockets like the Cinco are designed to...
Long burn, low thrust motors are not what you need for high drag designs. A medium thrust motor is better. A high drag design on a low thrust or regressive burn motor will arcs over under thrust...

As John Lee said, they are available exclusively on the Pinwheel page of my web site. However the price range is from $5 to $10 per kit depending on motor size (18 mm or 24 mm) and color. Most...
Try my Priority Stealth for free. I've flown it on F motors from the center of a volleyball court and it's landed in bounds.

Jogetorenk,
Welcome to the Rocketry Forum and thank you for the complement. I value my creativity above all else. You're new here so you might not realize that we aren't necessarily looking for...
I concur with Dick about the possible flight path of an under-powered, high-drag rocket but I don't think it's the thrust to weight ratio that does it. I think it has more to do with the amount of...
I have started shipping 5 of my popular kits in shiny Gold and Chrome finishes. More kits will be added soon.

In your pictures, the Helix is configured correctly.
The Helix is NOT the most efficient monocopter design possible. To make it safe, inexpensive and easy to build, I made some design choices...
Welcome from Kerrville. If you want to know who's hosting a rocket launch in Texas go to my Launches page.

Montaro,
It was a pleasure having you and your son at our launch. Your rockets were fantastic. :clap: I wish everyone was a creative as you. I'm sorry my poor camera skills in the video, did not...
If you do get it done at Kinkos or Office Max or another 3rd party printers, be sure to check the thickness of the cardstock. I use Georgia Pacific Image Plus+ TM that I get a Walmart. Some...
Many printers will print on cardstock if you feed them manually. Most big copiers, like the ones at work :wink:, can print on cardstock, so print the pattern out on regular bond paper and then make...
You fly it with the flat side down otherwise it won't spin.
Use a normal length rod, although depending on the motor and the wind a 18 inch rod is likely enough.
Art Applewhite
Yes, but it's not critical. If you let the motor extend mostly below the bottom, the rocket sometimes recovers "tail first", depending on the wind.
Art Applewhite
Possible but problematic. It uses aerobrake (tumble) recovery. To produce enough drag to make a safe descent with such a heavy motor, it would need to be big, i.e. 16 to 18 inches square.

I'm developing a new line of rocket kits called Pinwheels. They are based on the Pinwheel toy I played with as a kid, long before they invented X-Box.:y: I've posted a Micro Maxx version on my Free...
To eliminate any legal ambiguity, I've posted a Micro Maxx Pinwheel on my Free Stuff page.
Enjoy,

Yes. I'd like to the the results when you're done. My fingers are too big and clumsy to work at MMX size. I'm thinking you could start with a 50% reduction and use 67 lb index or maybe 24 lb bond....
I've added a new rocket to my Free Stuff page. It's the 13 mm Pinwheel. It's quick and easy to build. It flies well in small fields and spins like crazy. :y:

Do'h! I guess I should have read the whole thread first. :)

I would include rocket powered monocopters as real rockets

Nice flight. It looks a little over-built and therefore heavy causing it to descend much faster than it should.
