Brief

Sometimes a kit arrives in the mail and you immediately question the state of mind you were in when you bought it.  The Estes D.A.R.T. was that kit for me.  Picked up in an Ebay deal, I swear I have no idea what would have possessed me to even think of buying such an odd looking rocket.  The D.A.R.T. is a pretty standard 3fnc rocket hindered by a paint scheme that makes it look like the love child of the Cat In The Hat.  That said, it turned out to be a pretty decent performer. 

Components

  • BT-60 body tube
  • PNC-60 nose cone
  • 18mm engine mount kit
  • 3/32" fin stock
  • 36" Kevlar shock cord
  • 36" length of 1/8" sewing elastic shock cord
  • medium snap swivel

Construction

Instructions were typical Estes, well written and illustrated with nothing resembling a "gotcha".  The build itself was very standard, with the only change I made being the obligatory one of swapping in some Kevlar and a longer piece of sewing elastic for the tri-fold mount and too short rubber band that the kit came with.  Fins were first glued on with LocTite Gel CA, then secured further with double glue fillets of Elmer's Wood Glue.

Finishing

Finishing wasn't terribly hard, but it did pose the only challenge of the entire build.  After the glue had dried, the entire rocket was shot with a double coat of Valspar primer, then two coats of thinned Elmer's Fill & Finish, sanding between coats.  Since the entire body is to be painted blue, the only thing to do was decide what blue that might be.  After almost ten years back in the hobby, one tends to accumulate a large amount of orphaned spray cans whose contents can only be determined by checking the nozzle.  That was exactly what happened in this case.  The blue is a bright metal flake that has long since lost any identifying label, but never seems to run out.  I wish I knew where I'd bought it, because it sprays nicely and never seems to run, rare for a metallic paint in my experience.  The nose cone was sprayed with Valspar gloss white, then masked off and sprayed with Valspar Apple Red.  When the paint had dried, I began to pull the masking tape off and some of the white paint came with it, but none of the red.  Not wanting to do a repaint and since it easily passed the ten foot test, I left well enough alone.

Construction Score: 4

Flight

The first D.A.R.T. launch took place on a typically breezy VOA day, another of those circumstances where the dead calm at home became an iffy flying prospect at the field.  I don't drive 45 minutes to turn around and go home, so I put up four first timers.  The D.A.R.T. left the pad with authority on an Estes C6-5, cocking hard into the brisk breeze.  Despite the windcock, the flight was high and nicely stable over the south end of the field.  I started walking to the south at ejection, but stopped almost immediately when it became apparent that the rocket was going to come back close to the pad, if not over it.  The D.A.R.T. hit the ground hard, tail first, but sustained no damage despite one fin burrowing itself in the soft dirt.
