Default Interested in Large Size Cardstock Rockets?

Good Morning,

Been thinking about marketing some of my rocket designs.

One that might interest you is a 1/12 scale Mercury Redstone. Have the MR3 and MR8 versions.

Been flight tested using up to 80lbs of air pressure: https://www.youtube.com/watch?v=s_E29l4hnuc

Others that can be printed and sold: Saturn 1B and V.

These rockets will be printed on 2ft x 3ft sheets of cardstock. The Avatar picture used is the 1/32 scale Saturn V that uses 14-sheets.

For the big sheets I charge $15 a sheet. If someone PMs me and wants to try them here I'll drop the price to $12 a sheet (need to cover ink and paper costs-the ink in my plotter is designed for drafting not doing full ink paint jobs..) 1200x1200 dpi quality uses lots of ink fast!

Videos and photos. Yes the winged X-15 is an air pressure launch rocket as well. It is 4ft long as is the SR71. The SR71 is not a rocket, just a glider.

Old style Saturn V 6ft tall rocket launch using 94lbs of air pressure: https://www.youtube.com/watch?v=u-HFL79Rd-M&t=3s

New style Saturn V can be made any size up to 10ft tall.

Anyone interested? PM me or post here.

Wow, very neat! How do you converted any of these into model rocket engine powered rockets?

Also, could you give us an idea of how many sheets are used for each of the Rockets you've shown.

Thanks.

On the centering rings inside the rocket, there are different diameter cutouts for the different tubes. The model comes with a center tube that is 1.02" diameter. This can be replaced with BT tubes, by cutting the appropriate cutout..

For Air Pressure rockets the tube has a plug at the top. It works as a PSI tube to contain the compressed air from the tank. A ball valve releases all of the air at once. The tube has to be strong

By removing the plug you have a direct path to pop the nosecone off.

To use the tube that is full length in each rocket, it might be better to create an adapter from the engine to the PSI tube.

You'll want to use wood for the fins like a normal rocket.

I'll look at the different drawings and get a sheet count.

Really like your questions. Thank you.

Mike

Thanks, Mike. I've been on this forum for years and never seen anything offered for sale like what you're offering.

I know that Frank Burke of Dynasoar Rocketry flies some truly beautiful very large scale paper rockets.

Hi Steve,

Okay, did some checking. It has been some time since I've visited the drawings.

Special note in the Saturn 1B, about some idiot that designed a hard rocket to put together. I remember now, where the lower tubes meet the upper part I had troubles lining everything up, my notes tell how I planned to fix. I'll update for sure.

The Saturn 1B is 1/32 scale. It was done before I purchased Peter Always book, Rocket of the World. I'll need to update the rocket with better scaling and graphics. Sheet count is 8.

Full Size ARCAS = 5 sheets (only have the display version with the Teddy Bear) will need to re-paint to the Chey silver that the originals flew with.

4ft long X-15 = 5 Sheets

1/32 Saturn V 10.43ft tall = 14 Sheets [Rocket Weight: 2.237lb. / 1014.9gm]
1/40 Scale 8.34ft tall = 8 Sheets*
1/48 Scale 6.95ft Tall = 5 Sheets*
1/50 scale = 6.68ft tall = 5 Sheets*
1/60 Scale = 5.56ft Tall. = 4 Sheets*
*These have been updated in the drawing to verify sheet counts.

5ft long F-106 Delta Dart(R/C Capable) = 7 Sheets

Mike

Default Saturn V Size

After looking at a chart for Estes on engine size/max lift weight, decided to print one of the Saturn V out and test the weight to see if it will work for a D12-3.

5-sheets should put the model around 10 oz. D12-3 says it will lift 14oz.

1/48 scale at 6.95 feet tall. Wonder how much the increase in drag will work with the 14-oz limit.

A couple of minor updates to the drawing still to go. Looking at the centering rings that give it support-can they have holes in them to reduce weight. Thinking the answer is yes. There are 5-big ones 8.25" in diameter.

Mike

Default 1/60 Size Saturn V Parts Cut Out

All of the parts for the 1/60 Size Saturn V have been cut out. A few have been glued.

A couple of photos below.

1838 is the top part of the lower stages need glued to the main fuselage before rolling and gluing.

1839 Main Parts are cut out. Ziplock bag holds all the really small ones so they don't get scattered.

Default Main Parts Glued

Took 33-minutes to glue all the main parts:

A few photos showing the parts and a couple showing the 2" diameter PVC pipe with the double sided tape rings holding the big parts so I can glue them with ease.

1852 3rd stage getting glued on 2" PVC

1853 Stages 1 & 2 getting glued on the 2" PVC. You can see some of the older double sided tape rings. Placed 12" apart three of them hold the sheet in place while I glue.

1856 Same

1859 Parts

Weighed all of the parts, foam bulkheads, cardstock and Bt-50 tube, everything except for the glue and parachute. Total comes to 9.5 oz. Some of the major gluing has already been done on the fuselage shell. It should be close to the projected 10-oz for a D12-3 launch.

Hoping it is real close to my estimated weight total, if I get close that means the 1/48 should fly on a E12-4.

4ft long X-15 weighs 7.5oz before adding weight to balance. 10oz RTF.
