This is a very unique rocket t' own, me hearties, but because o' t' size o' t' fins, me bucko, it is best t' fly this on only calm days.

    (09/10/02) It is always nice to see a little uniqueness in rocket designs and that is exactly what Binder Designs' new (for 2002) Dragonfly has. Its fins, length and finish recommendations are all to help it look like a Dragonfly. According to Binder, the kit is " geared for the beginner to mid/high power ". I would agree, as it is a very straight-forward kit to build. But ...

I found the EMRR review of the Binder Design Dragonfly to be right on the money. The packaging, well written instructions, & ease of construction to be the highlights of this kit. Mine weighed in at a hefty 13.7oz but I can attribute the extra mass to the following: added Acme rail guides, probably 3ft of masking tape to get the NC to fit properly, added/used 2 additional quick-links for chute & NC, filled the fin can with PML expanding foam (vs. internal epoxy fillets), & added 1.1oz of weight in the tip of the NC to help bring the CG forward to ensure stability for flights on any Fs or Gs. I would definitely recommend this rocket as an entry level MPR.

This is a great rocket from a very well done kit/manufacturer. Every piece in the kit was of high quality, and it went together easily. My 10-year old daughter was the primary builder. I suggest a little dog barf behind a Nomex? chute protector to protect the recovery harness, which is slightly on the thin side (I don't want it to burn through over a few flights). Mine was on the heavy side at 15.6oz but flew straight as an arrow. Stock chute a little fast at this weight. I may need to upgrade it. Stock chute is brilliantly designed with shiny silver on top, solid black on the bottom--easy to see in flight or on the ground. I also added 0.5oz nose weight, plus foam inside the nose cone.
