Scratch - Astron Drifter (Scratch)


Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Bill Eichelberger


I would have eventually built an Astron Drifter just because I like the history and tradition of the K-kits, but a late night Ebay "Buy It Now" spree netted me an Estes lot that included a lot of vintage nose cones, parachutes, parts and etcetera.  One of the nose cones in the group was a painted and obviously used BNC-50K.  I'd already built Cobra and Alpha clones with a balsa cones, so the choice came down to the Trident, Sky Dart or Drifter.  I wasn't interested in taking on a project as complicated as the Trident or Sky Dart, so the Drifter won by default.


  • BNC-50K nose cone
  • BT-50H main body tube
  • BT-20J engine tube
  • 2 RA-2050 entering rings
  • EB-20A engine block
  • medium screw eye
  • 2 medium snap swivels
  • 24" Kevlar shock cord
  • 24" length 1/8" sewing elastic shock cord
  • 3/32" balsa fin stock
  • shroud pattern
  • 1/8" launch lug

Favorite Rockets: Nike Anything


I had my start in rocketry when I was 11 years old.  Estes Alpha Starter Kit.  I still have the launch pad.

BAR in 2005 when I found the DART club.  What a great bunch of people.  Got into HPR thanks to Andy Woerner.  Thank goodness I didn't have to finish filing my LEUP.  What a pain.

Currently taking it easy in HPR for a while, spending more time working on my skills in NAR competition and NARTREK advanced levels.  I held a NAR record once for about a month.  I'll have to go higher next time.

Going out once in a while to launch rockets is great.  Having a mission makes it much more interesting.  More people should do NARTREK and the EMRR Challenges!  Bring it on!

Model Rocket Building: Letter From Vern Estes - 1970
I thought I'd misplaced this one! Here's a letter I received from Mr. Estes dated February 19, 1970. I had hand written a letter to Estes (not directly to Mr. Estes) explaining my troubles getting a BP engine permit in California. Rocket engines and fireworks were tightly restricted back then. Mr. Estes asks: If I had an area (a flying field) to launch cold powered Vashon rockets why couldn't that same place be used to fly BP model rockets? I couldn't buy BP engines without a permit. My mother made a few calls and got the Assistant California Fire Marshall to approve the family artichoke ...

Rocket Dungeon: Interesting oddroc from LDRS 33
These came from Liberty Launch Systems/ROCKETS Magazine's LDRS-33 Saturday album . The rocket didn't seem to fly 100% straight but appeared to recover just fine. I'm hoping Neil will talk about it in the launch report. (Photos by Neil McGilvray, used with permission.)

Rocket Dungeon: Inductor, the build, part 1
I proceeded to build my finless, induction stabilized rocket, the Inductor . The phenolic liner from a Loki 75mm motor is the perfect size to accept 12oz aluminum soda cans...just a tad off from a 2.5" body tube. I didn't want to use the liner and briefly pondered building an 18mm rocket from BT-60. However, I ended up rolling a tube from poster board, 3M "77" spray adhesive, and using Loki casting tube as a mandrel. Quick and sticky. The spray adhesive seemed to work well...until I sprayed on some primer, which promptly caused the tube to start peeling. A little epoxy and a strip of ...
