REC'D MOTORS: B6-0, C6-0, ALL Aerotech 18mm Single Use and RMS 18/20 reloads

[Picture](07/01/03) I finally got around to purchasing a couple of Art Applewhite's Flying Saucers. Been meaning to, just never got around to it. When I did, I was glad he accepted PayPal. Made it very easy. I purchased the Gold 6" 18mm Delta Flying Saucer and the Gold 4" 13mm Delta Flying Saucers.

I'm writing the review for the 18mm version because there isn't currently a review on EMRR. But I have to admit the same thing Dick Stafford did, these kits all build just about the same! There was virtually no difference between my build experience on the 13mm version verses the 18mm version. In addition, there are very few parts, four to be exact: 1) Top Cardstock, 2) Bottom Cardstock, 3) 18mm motor mount, and 4) Foam Center.

Rocket PicCONSTRUCTION:

The instructions are printed on 3 pages of 8½ x 11" paper. They include black and white photos to assist in the building process. The tools and supplies that are needed are outlined: Scissors, #11 Exacto® Knife, Elmer's Glue-All® and 150 girt sandpaper. That's it and you're ready to go.

Assembly is simple. Cut out the Top and Bottom from the cardstock. Cut out the Top and Bottom Seam pieces from the card stock. Glue the Seam (tab) onto one side of the Top. Let dry. Glue the other side of the Top onto the exposed Seam (tab), thereby forming your Top Cone. Repeat for the Bottom Cone.

Using your hobby knife, cut out the Center from the provided 1/4" foam board. Cut out the center of the Center (which is the motor mount hole). Now you are ready for the most difficult part of construction; cutting the 30 degree bevel on the outside edge of the Center. Be sure to use a new blade and take your time. Doing those two things makes this a lot easier than it sounds.

Once the Center is prepared then final assembly is relatively simple. You glue the Center to the Top. You then glue in the motor mount. Lastly, you glue the Bottom to the motor mount and Center. Apply some fillets on all the seams and ta-da... you're done.

Overall, for CONSTRUCTION I would rate this kit 5 points. Not sure how it could be any easier!

Rocket PicRocket PciFLIGHT/RECOVERY:

Art Applewhite recommends a C6-0, B6-0 or a RMS 18/20 Reload. The motors are to be friction fit into the motor mount with the warning that no motor should stick out further than ½" from below the motor mount.

I have flow the 18mm version 3 times, all on B6-0's. I was planning on using this as a demo rocket for my son's kindergarten class, but that never worked out. It would make an excellent demo rocket, and it would even make an excellent school project rocket!

All the flights were the same, straight up, invert and right back to us. Altitude? Hmmmm, maybe 30 feet. Hard to say, but it would make a good backyard flier.

For FLIGHT/RECOVERY, I would rate this rocket 5 points. I don't see any way to knock a rocket that has no recovery system to fail, no need for wadding, no need for motor retention (although that could be the only thing to add), and always comes back to where you are!

I give the rocket an OVERALL rating of 5 points. Yes, it is a "perfect" rocket for its price, instructions, assembly and flight characteristics. Go give one a try!

Brief:
I was fortunate enough to win this kit as a prize for entering my Barbsari B-Prize design into Descon 15. I asked for and received the Spaceship Earth version. I was amazed at how quickly the shipment arrived after I'd specified what version I'd like. Mondo kudos to Art Applewhite for fantastic service.

Construction:
The kit includes a sheet of printed cardstock for the top and bottom cones, a dark blue sheet of foam-backed board, a 2.75" length of motor mount tube, and instruction sheets. The cardstock and foam board are marked with labels, cutting lines, and tab alignment lines. The cardstock graphics for the top and bottom cones include beautifully detailed natural-coloured images of planet earth stretched to accommodate the cone shapes. The bottom cone has a large image of Antarctica. The top cone shows the other continents and the northern ice cap in gorgeous detail. Super cool!

The instructions are clear and concise, with large, crisp, clear photographs to add that extra amount of clarity. Critical notes are boldfaced and underlined to draw the builder's attention. The assembly order was sensible and straightforward.

The instructions recommend using a brand new, extremely sharp blade for cutting the foam board for good reason. The foam tends to tear easily, leaving small voids. As long as the voids are small, this is not too much of a problem since the foam edges are not covered by the top cone.

When forming the cones, I noticed that the exposed white edges of the cardstock were very noticeable against the dark blue graphics. I remedied this by using a dark blue felt-tipped marker to darken the edges. I feel that this greatly improved the look of the finished model.

Edge Another issue is that I had to be very careful when applying glue and making fillets to avoid messing up the gorgeous graphics. The cardstock graphics are very durable, though. They stand up to much handling without any sign of bleeding or distortion.

Finishing:
All of the parts are printed, so no further finishing is needed. The instructions recommend a coat of clear enamel or varnish, but I haven't done this yet. I will do, though, before the snow flies.

I had some trouble smoothing the edge of the saucer where the top cone meets the edge of the foamboard. Though the foamboard edge is just cardstock, it just doesn't want to smooth down the way I'd like, even after careful sanding.

Construction Rating: 4 out of 5

Flight:
Flight preparation is dead easy, since there are no recovery mechanisms to set up or care for. The instructions recommend wrapping three layers of masking tape around the base of the motor as a thrust ring. I think this is good practice, as the motors I've tried slide pretty easily into the motor tube.

If you don't want the motor to pop out at ejection time, you'll probably want to add some tape to the middle of the motor, but be careful not to make it so tight that its tough to get the motor out again after flight.

The saucer's first flight was at a model rocketry demo at an event at a city park. The flight field was pretty small, surrounded by trees, so low drift was very important. The wind was around 10 mph. I took a B6-0, wrapped some tape around the motor's base, and a little in the middle, inserted an ignitor, slipped the motor into the saucer, and popped the saucer onto the pad. I used an alligator clip on the launch rod to support the saucer 6" from the pad, as recommended in the instructions, then clipped on the ignitor wires. All prepped!

The saucer boosted straight up with no wobble, flipped over at end of boost, and floated softly down to earth with no wobble and little drift. Perfect flight for the demo.

The second flight was in a wide open field with 10 mph winds, again with a B6-0. Again the flight was straight up with no wobble and little drift. The model flipped over after boost and float safely to earth, again with no wobble and little drift.

Recovery:
Flight recovery was very easy after both flights. The saucer hadn't drifted far from the pad after either flight. The saucer's decent was slow and gentle both times without damage.

Flight Rating: 5 out of 5

BottomSummary:
The Art Applewhite 18mm Delta Saucer is a simple high-quality kit that assembles quickly with no nasty gotchas. It performs well on the field and is great for demos in smaller flight areas. The Spaceship Earth version looks spectacular. It is a solid, rugged design and the printed graphics stand up to handling... a great rocket for handing around in classrooms. Flight and recovery are smooth, stable, and entertaining.

The only con I can suggest regarding my own model is that the joint between the top cone and the foam board is kinda rough resisted attempts at smoothing.

Overall Rating: 4 out of 5

GUEST's OPINION:
07/03 - "I agree with this review: they are indeed quite simple. I got several, including the 6in, 18mm gold saucer. The gold cardstock is very cool. 1.If you get white glue on it, don't panic: simply scrape the glue off with your fingernail. 2. It is quite reflective and resembles a "real" flying saucer. 3. Read what Mr. Stafford said about the gold cardstock. These flying saucer kits are just that: kits. They are, however, well thought out. Mr. Applewhite did a good job on the foam board, which has a circular line drawn just inside the outer edge to make cutting the bevel a lot easier. The foam board also makes the saucer a lot more sturdy. One thing about the launch lug holes: the ones on the shrouds fit a 3/16in rod, but the one in the foam board fits the 1/8 rod. Solution: cut the launch lug hole in the center bigger." (B.B.)

12-20-2003 Lance Alligood Est SU C6-5 None - Tumble 5-10 mph winds SCRATCHBUILT - Nice straight flight to less than 150ft. Silly me I forgot to remove the cap on the launch rod before takeoff & it damaged the top shroud of the saucer! Can be fixed with tape. VERY slow & soft recovery.
03-20-2004 Lance Alligood Est SU C6-5 None - Tumble 10+ mph winds SCRATCHBUILT - Great comparison flight to its sibling Qubit. Great flight.
07-14-2003 Bill Bill Est SU C6-3 None - Tumble 0-5 mph winds - Another cool flight. Doesn't go high on the extra burn of the C6. Ejected charge went off close to ground.
08-07-2003 Bill Bill Est SU C6-3 None - Tumble 5-10 mph winds Gold - Angled launch rod, not a good idea. Boost was good, but rocket arced and landed on a roof. Somehow, the saucer managed to roll off!
08-16-2003 Bill Bill Est SU C6-3 None - Tumble Calm Gold - semi-night launch: absolutely straight flight, with sparks flying off C6. Ejection charge threw a nice fireball. Rocket came down very straight and landed about 25 feet from pad.
07-06-2009 William Carpenter Est SU C6-5 Very Late 0-5 mph winds - Nice, stable flight to an estimated 75 to 100 feet. Recovered very close to the pad.
04-27-2003 EMRR Est SU B6-0 None - Tumble 0-5 mph winds Gold - Excellent. Low altitude but an outstanding flight.
05-31-2003 EMRR Est SU B6-0 None - Tumble 0-5 mph winds Gold - Great flight. Repeat of first.
