Art Applewhite Rockets - Dragonfly Monocopter (18mm) {Kit}

Manufacturer:Art Applewhite Rockets

Contributed by Dick Stafford

You have to love a rocket that assembles quickly and that can be flown in your front yard (and not that big of a front yard either)! That's what you have with the 18mm Art Applewhite's Dragonfly.

I brought this kit, a hobby knife, a ruler, a pencil and some Elmer's Glue with me on a short business trip. I was successful in building the kit while in the hotel one night and finished it in the AM the next day. It was that easy.

Dragonfly with Pad

The Dragonfly comes with a 3/32" basswood wing, a 1/4" Balance Beam dowel, two 3/16" support dowels, a motor tube, some fiberglass tape and a piece of 3/32" basswood that is used to create the support pieces. That's it.

CONSTRUCTION:

The instructions are printed on three pages of 8½ x 11" paper. The last page focuses on flight and the building of a monocopter launch pad. There are B&W pictures and illustrations to ensure an easy build.

There is very little cutting that takes place. The Center, Center Support and Motor Support are all cut out of the small piece of 3/32" basswood. Then later in the build, the fiberglass tape needs to be cut to fit around the motor mount.

Building is logical and easy to follow. You do have to pay attention to the pictures to ensure you are gluing the supports, dowels and balance beam on the right sides of the center.

On the PadMy only slight tweak to the instructions would be in step 4 where it simply says, "Glue the Balance Beam to the Center". There should be some indication that this should be centered and equally spaced on both sides of the Center.

One interesting step is placing the fiberglass tape around the motor tube and securing it to the support. This requires the tape to be cut out to clear the support dowels and then to be cut to the length needed to fit. Once the cutting is done, it is glued in place. Then the weave is filled in with Elmer's Glue making a nice secure motor mount.

Now, I did say that I built the rocket at the hotel, which is true, but I completed the final step at home. That was the drilling of the 1/4" hole in the center for the launch rod.

I made my launch pad using the basic idea outlined in the instructions. Amazing that you only want a 1/4" long launch rod!

I didn't paint or finish the rocket in any way.

Overall, for CONSTRUCTION I would rate this kit 5 points. Fast, easy, and quality materials. Instructions were easy to follow. Also, I believe that some may avoid trying to make their own monocopter and Art Applewhite has now made it as easy as 3, 2, 1.

FLIGHT/RECOVERY:

Round and RoundThe Dragonfly is simple to prepare for flight. All that needs to be done is that you wrap a 3/8" band of masking tape around the motor to make a thrust ring. Then install the motor.

First flight was on an Estes C6-3. After ignition that rocket whirled quickly and took off. My guess is to about 70 feet. It then stopped, seemingly pausing, and then it fell to the earth. On the way down the ejection charge fired. The fall was rapid with the motor tube leading the way. I'm guessing that is another reason to use the fiberglass.

The next flight was a repeat flight using the C6-3. Again, nice performance. After this flight I noticed a small burn hole starting on the outside top of the motor tube. (Flight Video Below)

B2-5For the third flight I tried something special. I had an old Apogee B2-4 motor. I drilled out the center of the C6 thrust nozzle until the B2-5 slide into it. I then applied tape to the forward end of the B2-5 so that it stayed centered in the old C6 case. I then loaded it into the Dragonfly.

The flight was cool. It didn't come off the pad as quick and it almost seemed like a slow motion flight, but the thrust was adequate and with a 3 second burn, it was neat to watch. I miss those old Apogee Motors! (Bottom Video Below)

For FLIGHT/RECOVERY, I would rate this rocket 4 ½ points. Exciting low altitude launches that look and sound different. Nice appeal. The only detractor would be the burn hole that appeared after the second flight.

I give the rocket an OVERALL rating of 5 points. This is one of the relatively lower priced rockets that you just "have to have".

Biography:

I have ben doing the "BAR" thing since about April 2008. I was fortunate enough to get the picture of my Estes Maxi Brute X-Wing on the home page of Rocketry planet in 2009. Too bad that Rocketry Planet is no longer out there.

I have been having a lot of fun building and flying rockets. This is a great resource.

Model Rocket Building: ASP D Region Tomahawk Build, Part 1, Parts
I've always like the D Region Tomahawk, a clean looking sounding rocket. The first on I put together was the old Competition Model Rocket version. I remember (unsuccessfully) trying to emboss rivets on the upper bands. This Aerospace Specialty Products kit should be much easier. Smaller with less detail, still capturing the feel of the real thing. Parts are of great quality. My past experience with ASP kits have been very good. The ASP 18mm Corporal was a favorite build. That craft stick is used to apply glue inside the tube for the engine block. Parts of interest: The yellow engine block ...

Model Rocket Building: Estes Apollo Little Joe II, Background
Here's the Little Joe I remembered wanting. The BIG 1/45 Scale Little Joe II from the 1969 Centuri catalog. To see the catalog, CLICK HERE But $12.95? All I could afford was the smaller 1/100th scale Little Joe II. The fin fairings and some trim was vacuum formed. They were lightweight but fragile, much like the Centuri Saturn V fins and fairings incorporated into the Estes re-issue Saturn V kits. The "metalized" wrap was pre-installed at the factory. To see the original Centuri instructions: CLICK HERE The body and capsule came down separately on two 24" parachutes. A three engine cluster. ...

Model Rocket Building: Estes STM-012 Kitbash to the B32-M Spike, Background
Well, I thought it might work! I bought two Estes STM-012 kits on Ebay with the hopes of kit-bashing one of them into an AMRAAM. It never even occurred to me that the STM-012 model would have three through-the-wall fins. The AMRAAM has two sets of four fins. I would have to buy a couple new lengths of BT-60 to do the conversion. That, and the STM-012 nose cone was long! So the kits sat for a few months with me wondering what to do with them. Then I remembered this design from Madcow: The AGM-33 Pike . I've always like the looks of this one, I did the instructions for their 1.6" diameter kit. ...

Model Rocket Building: Corner Chip Fill - TIP
Well, we've all been there - the balsa grain runs in such a way that the trailing edge tip can break off. If the tip break is small you can fill it. Sand off some balsa dust from some scrap balsa. Don't sneeze. Apply some yellow wood glue to the broken corner. Use wood glue for this, yellow glue can be easily sanded. Press the glued corner into the balsa dust pile from all sides. Let the balsa dust and glue dry. Note in the inset picture that the dust and glue is a little larger than the chip area. Here's the same filled corner after filling and sanding to surface. Not perfect, but ...

Rocket Dungeon: Mini Higgs build, part 1
I dug into the build at the very best place to start - at the very beginning, which in this case is the motor mount. This is not so different than any other LPR mount. It includes rings (squares in this case), a motor clip, motor block, etc. The mount also has two normal round rings to hold the clip securely in place. The Kevlar leader is attached behind the forward square centering ring. Unlike any kit I've had, it also includes a section of shrink tube to protect the lower several inches of the Kevlar. I pretty much built this stock. If I want to put a bigger motor in one, I will have to ...
