Art Applewhite Rockets - Delta Flying Saucer 38mm (18") (Kit)

Manufacturer:Art Applewhite Rockets

Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Dick Stafford

Art Applewhite Level 2 Delta Saucer (beta)

This was a pre-production version of the kit and its construction varied somewhat from the production model. Nonetheless, it is representative of the performance you should expect from the production model. I have tried to indicate where the production model varies, however, these notes may not be all-inclusive.

This rocket is a huge, 18" diameter, Level 2 capable version of Art's Delta saucer. It is built primarily from Gatorboard and includes both 38mm and 54mm motor adapters.

Certification Level: L2 Tripoli

Favorite Rockets: Packers Backer (a Binder Design Thug)


I'm a BAR and have been flying again since 2003. 

I'm a member of Tripoli Central Virginia #25.  Our launch site is called BattlePark since it is located on the Cedar Mountain Battlefield near Culpeper Virginia.

I earned my Level 1 certification in 2007 with a scratch built, dual deployment rocket on an Loki I110 moonburner motor to and altitude of 4,200 ft.

My level 2 certification flight in 2009 was with a K695R to 6,828 ft.  The nose cone was lost so I put one on from another rocket and flew it again an hour later to get the cert.  As of 5/12/12 that rocket, called GrapeShot, has flown 15 times now, reached 9,559 ft and Mach 1.2.  It's the workhorse of my fleet and has taken a lot of punishment over the last three years.  It has been solid and never need a repair, knock on wood! ;-)  12/8/12 zippered the payload tube on GrapeShot.  Don't know how.  The apogee deploy worked, it was falling and the main RC controlled chute deployed but never opened.

Had my first motor CATOs in January 2014.  Both Hobbyline G64W-10 motors had blow by past the delay grain and used the powder well as a second nozzle.  The fwd closures were toast, as was the rocket DNA.  I believe the delay insulator was too small, the delay grain would fall out of the fwd closure.

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 ...
