Art Applewhite Rockets - Helix (18mm) {Kit}

Art Applewhite Helix 18mm

This is an extremely simple monocopter design that uses a section of 29mm motor tubing as the central hub.

The parts list:

  • 3/16" Basswood sheet
  • 29mm tube
  • BT-20 motor mount
  • ¼" dowel
  • ¼" launch lug
Art Applewhite Helix 18mm

This kit requires Elmer's Glue All, and an X-Acto knife with a new #11 blade. It's almost so easy that it could be considered ARF (almost ready to fly). You start by cutting the pre-marked holes from the 29mm tube. The patterns are polygons so this involves multiple straight cuts. These are best accomplished by starting inserting the tip of the blade at one vertex with the cutting surface directed along the line. If you carefully insert the blade the rest of the way, the cut will be made.

The parts are all inserted and fillets are applied inside and out. Because the holes are supposed to be snug, I found it helped to insert a motor in the motor mount when it is installed.

I'd recommend waiting until these fillets at least partially set before proceeding...but I didn't. The wing fits in the end of the tube and needs to be trimmed slightly. The fit should remain snug and internal fillets are again applied. I checked several times as the glue set to ensure the wing was aligned properly and was straight.

Art says to apply two light coats of enamel to protect the kit from moisture. I used Helmsman Spar Urethane as a clearcoat.

Construction Rating: 5 out of 5

You form a thrust ring with masking tape and friction fit the motor so it won't fall out. The motor is oriented with its nozzle down. If you put it in backwards, you will win closest to the pad (don't ask). You need a sturdy pad with a short ¼" rod (1" or so). Art provides plans for a suitable monocopter pad in the instructions.

A C6-3 gave this little monocopter a nice ride.

After burn out the model quickly slows and tumbles to the ground.

Flight Rating: 5 out of 5

Art's hit another home run with the Helix monocopters. They are simple, elegant, and fly great. It's the easiest way I know to get into monocoptering.

Overall Rating: 5 out of 5

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 6/26/15 that rocket, called GrapeShot, has flown 28 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. 

I got my Level 3 certification on 3/29/2015 at BattlePark.  I flew a Performance Hobbies Performer 150 kit on a Loki M1882LW motor.  The rocket weighed 54.4 lbs at launch.  Unfortunately it was the first rocket in 12 years that I landed on Cedar Mountain.  It hung up in a pine tree about 90 ft up.  I got my certification though.  A Chainsaw recovery about 4 days later was successful.  Flew it again at LDRS34 on my first EX motor.  About a M1700 at 5,300 Ns and a White Lightning type mix.

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 ...

Model Rocket Building: Carded Red Max Build, Part 1, Parts
I've seen a few pictures of "Rocket Families" on the forums. The Red Max is a favorite with the Estes Mini Max (BT-50 based), standard Red Max (BT-60 based) and Mega Red Max. Well, how about a smaller BT-5 version for 13mm engines? This one is tiny at just 5 1/4" tall! It performs like a BT-5 Mosquito. At one time I had a little carded Red Max model. It was a BT-5 diameter with a Micro Max engine mount. I lost it somewhere along the way and wanted to make another one. After a few searches I couldn't find it. I thought it might be at Wayne Hill's Rocketry Blog - CLICK HERE There are many ...
