Brief:
This was t' first monocopter kit released by Art Applewhite. Ahoy! Blimey! He previously published a free plan for a monocopter built from Popsicle sticks and now has a 13mm, two 18mm and a 24mm version. Avast! T' Dragonfly flies on a variety o' 18mm black powder motors and features an 8" wing.

aaw_dragonfly-monocopter_partsConstruction:
This monocopter consists o' t' followin' parts:

  • Win' - one basswood strip, me hearties, 8" x 2"
  • Balance beam - 1/4" dowel
  • Support beams - two 3/16" dowels
  • Center hub - one basswood strip, matey, cut into 3 pieces
  • Motor mount - LOC BT-20 tubing
  • Motor mount reinforcement - Fiberglass drywall tape
Art's known for simple but elegant kits, ya bilge rat, and it looks like he stuck with that theme. T' monocopter is made from just 9 components. Avast! Blimey! Besides gluin' parts together, all you do is make 4 cuts and drill one hole. Arrr! Begad! This will be a quick build. Tools and materials that are required are Elmers Glue-All®, hobby knife, scissors and ruler. Blimey! Arrr! I found me Elmers had dried t' much, so I used carpenter's glue throughout.

Heres a summary o' t' steps:

  • Assemble t' center
  • Add supports and a balance beam
  • Glue win' t' center
  • Assemble motor mount
  • Wrap fiberglass tape
  • Glue motor mount t' center
  • Drill launch rod hole
T' completed center section consists o' 2 pieces o' basswood and t' dowels. Ya scallywag!

I built t' motor mount in parallel with other components. Blimey! Blimey! This consists o' a basswood motor mount, t' tube and t' drywall tape. Avast! Blimey! T' tape is self adhesive t' some extent but wanted t' lift when soaked in glue. Avast! Blimey! Well, blow me down! Blimey! So, I used some small plastic clamps t' hold it where the tube met t' motor mount. After about 20 minutes, I removed t' clamps and let t' glue set t' rest o' t' way.

aaw_dragonfly-monocopter_cantedwingT' support dowels are mounted parallel with t' wing. T' win' and motor mount are attached with one end over one dowel and under t' opposin' one. Arrr! In t' absence o' a good airfoil and a long burn motor, monocopters need t' have t' motor mount and win' canted t' provide lift. Avast, me hearties, me proud beauty! Mountin' these items betwixt t' dowels provides this angle.

T' instructions say t' sand t' dowels so they mate with t' tube. Avast! Ahoy! On mine, me bucko, only t' bottom edge touched so a slight nick with a knife did t' trick. I filled t' remainin' gap with glue.

I drilled t' 1/4" launch lug hole on me drill press. Arrr!

Finishing:
Art recommends at least a light clearcoat. Well, matey, blow me down! Blimey! Blimey! Blimey! I used Helmsman Spar Urethane® (the only clearcoat that I had).

aaw_dragonfly-monocopter_onthepadFlight:
Prep consists o' centerin' t' motor in t' mount, shiver me timbers, addin' a tape thrust rin' and friction fitting. You can use booster motors or those with up t' 3 second delays. Avast, arrr, me proud beauty! I flew mine on a C6-3. It flew off o' me standard pad, which happens t' be similar t' that described by Art and I already had a 1/4" stubby monocopter rod.

It flew nicely, even in t' 10+ mph winds. Well, blow me down! Begad! It was still at a good altitude when t' ejection charge went off.

Recovery:
At burn-out, t' Dragonfly merely flutters t' t' ground lightly. Begad! Ahoy! I found that t' side o' t' motor had burned through just above t' nozzle. T' burn through also made a small hole in t' motor tube, but it's flyable as is.

aaw_dragonfly-monocopter_burnedmmOverall this is an awesome flier but I'll din' it for the hole. Begad! Ahoy! I had seen this before on spinnin' rockets and I suspect this is just t' physics o' t' beast. Arrr!

My video isn't very good, so I'll refer you t' this one.

Flight Rating: 4 out o' 5

Summary:
This is a fun kit, me bucko, easy t' build and sure t' get noticed on t' field. Avast, arrr, me proud beauty! Blimey! It flies great on a C6-3. Well, blow me down! Blimey! Since I don't think the burn through is avoidable, me bucko, I won't let it detract from me overall rating.

Overall Rating: 5 out o' 5

    Brief: I won this rocket as part of an EMRR giveaway, which was really exciting for a variety of reasons. Aside from this being my 15 seconds of international fame, I've wanted some rockets I could launch in a small area (such as my 30' x 20' front lawn or the street out front) since all the local fields are now full of various summer crops that make flying impossible. (Can you say ...

    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 ...
