Clone - Estes Sentinel (Scratch)


Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Bill Eichelberger


The Sentinel is a very convincing faux-missile produced by Estes from 1988 to 1994.  Originally an 18mm bird, I built my clone with a 24mm mount, a decision that I've been quite happy with.  Mine isn't a kit, but a clone built around an original PNC-60RL nose cone.

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: Peter Alway Saturn IV Build, Part 1, Plans and Parts
This model was from Peter Alway's Home Page. I can't seem to find it now! If anybody has a link, let me know. The website had plenty of sport and scale plans including a Vostok, Saturn I and a Flying Rabbit that looks better than the old Estes Cloud Hopper. You can get Peter Alway's books: Rockets of the World HERE and Scale Bash HERE Both highly recommended! There's one model that has been on my "to-do" list for a while. The SATURN IV!
