Always Ready Rocketry - Blue Tube 2.0 (Component)

Manufacturer:Always Ready Rocketry

Contributed by Cliff Oliver

This review is focused more on the Blue Tube 2.0 material than the rocket I built. The rocket was constructed pretty much like any other HPR rocket - with three 'glassed fins and an altimeter bay for the dual recovery system.

I acquired the Blue Tube 2.0 items from Always Ready Rocketry. I had heard the good and the bad points of the original Blue Tube and wanted to find out how the 2.0 version performed. The body tube I received was a single 48-inch tube. I was pleased by this because, if you want to build a longer rocket, you don' t have to splice as many shorter tubes together to make up the length. Randy at Always Ready Rocketry advised me to use a sanding sealer on the airframe to seal it from moisture. So, I used some that I found at my local home improvement store. Following the instructions, I applied the sealer in smooth coats and sanded between each. After three cycles of applying and sanding, I measured the tube and made the cuts for the payload and booster sections, the one-inch band for the altimeter bay and two 1/4 inch bands for the interior stops for the altimeter bay bulkheads. I used my compound miter saw with a rough cut blade for this. If you use this method make sure you let the blade go through the material slowly. Otherwise, it will tend to burr the edges. I also used this method to cut the motor mount to the length I wanted.

The sanding sealer did a fair job of filling the deep spiral lines in the body tubes. I used spot filler putty to finish them. Remembering that one of the chief complaints about the original Blue Tube was warping when it got hot, I painted the upper payload section gloss black. To make a comparison, and to make it easier to see, I painted the booster section orange.

At the SEARS 572 October launch I purposely placed the rocket in the sun lying on its side in the grass. The weather that day was sunny and the temperature was in the low eighties. After several hours of this I checked for any warping. None was detected. The slip joint fit had not changed either.

I flew the rocket, which I named "Blue Tuber," on an Aerotech I211 motor to an altitude of about 2900 feet. The flight was straight and it suffered no damage.

I like the Blue Tube 2.0. It is very strong material that is not brittle like phenolic tubes. The changes that have been made seem to have corrected some, if not all, of the issues reported on the original Blue Tube. It is a little pricier than phenolic tubing. But, if you want a strong airframe, that does not need further reinforcement, I would suggest looking at Blue Tube 2.0.

Odd'l Rockets: SPUDNIK Flight Testing
I launched the SPUDNIK twice yesterday morning, both times with a A10-3t engine. Both flights were stable to about 100 feet but there was corkscrewing. The Odd'l Rockets Sputnik (with the 3" foam ball) flys vertical without any "coning" or corkscrewing. The problem is trying to drill out a straight 1/2" hole for the engine mount tube. If the line of thrust is off by a degree or two the rocket won't fly perfectly vertical. Add the uneven surfaces along the top and it probably won't fly without some spiraling. Drag and weight are other considerations. On both flights the model was nose down ...

Model Rocket Building: Estes Patriot Build #2056, Part 1, Parts
Everybody has built one of these, except me! This build will be a little different. At the bottom of each post I'll be keeping track of how long I take on each step. These are my personal build times, I tend to take longer on rocket building than most people. I don't keep track like this very often, it's a bigger effort to keep recorded build times. There will be upgrades. A BT-60 model at over 21" tall should probably be D engine capable. You can always drop in a 18mm adapter for smaller fields. A payload section will be made using the upper yellow tube section. All the parts: ...

Greg Smith's Blog: Der Red Mix mark II Skidfest at ROCTober 2014
After talking it up for over a year I finally flew my scratch-built Der Red Mix mark II on a full complement of seven burly Skidmark motors (as always switching to 720p in full-screen mode is the shit): A formidable liftoff featuring loud, flaming titanium granules: And notably angled ascent: I arrived at the lake bed later than I'd have preferred but the conditions were perfect all day with light, intermittent wind and perfectly clear skies. I had prepped all the electronics two months ago so I only needed to load up the seven Skidmark motors, set up the CD3 ejection system, mount the Flip ...
