Estes Pro Terrier-Sandhawk: Advice or suggestions?

Post by Kevin Drays » Sun, 09 May 1999 04:00:00



Hi all.

I stumbled onto a treat today, and grabbed a Terrier-Sandhawk kit that
was part of Estes ill-fated Pro series. The price was even reasonable!

Other than the usual ideas (longer shock cord, nylon chute, etc.), is
there any other pieces of advice regarding this kit? From a brief
look, I'd say that it appears to be the least involved Pro kit I've
seen (Haven't seen the Impulse), with lots of injection-molded plastic
parts.

I'm thinking that gap-staging might be possible, or upgrading the
Terrier motor mount to 29mm.

What does the RMR hive-mind have to say? :-)

  Hi, Kevin:
  There is an article in Sport Rocketry, I believe sometime in '95, about
electrically staging an old Estes Nike-Apache with a capacitor and mercury
switch in the transition.  I believe that this would work great in the
Estes pro series Terrier-Sandhawk.  If you do not have or cannot obtain
this article, send me a personal e-mail and I'll get a copy to you (if
you're interested, of course).

I too recently acquired this kit so I would also be interested in any
suggestions..  Pretty decent looking kit!

I'm tempted tos say that you've just bought yourself an excellent Sandhawk kit,
and a nice bottom half of a sport model, too.  The Terrier fins are way
oversized, and the suggested paint pattern is wrong.  There's not a whole lot
to the booster but a tube, fins, and an adapter, and a coat of paint so at 1/2
way off, I'm probably just going to make mine into a very nice Sandhawk,
cheaper than some crazy classic kit auction.

Thanks for the heads-up, Peter. Since I *did* manage to scrounge up a
copy of RoTW, I'll have to see what I can do to the kit. At the very
least, I'll make sure it's painted accurately!

(Looking forward to the sequel, btw)

Thanks, Dave.

I'm afraid I'm not quite ready to start playing with electronics just
yet, so I think I'll pass on this one. Nifty idea though.

Estes Pro Terrier-Sandhawk: Advice or suggestions?

I also found one of these a while back. I have heard from others that
the coupler between the Sandhawk and that "almost-a-Terrier" booster is
weak, and tends to break. I am considering finding a way to strengthen
it. I was thinking of fiberglassing it inside. However, I am not sure if
the epoxy will even stick to the plastic that is used. Any sugggestions
or ideas to beef up the coupler?

Also: Not only is the color scheme incorrect, the decal for the booster
is in black, and ROTW says the lettering is red. The color of the fins
is shown as white in the kit, but black in ROTW, which brings up my next
concern: Will those plastic fins warp when the sun beats on them if I
paint them black?

Keith,

I wrote that article, and it can be found on the rmr archive site:

http://metalab.unc.edu/pub/archives/rec.models.rockets/PLANS/

Look for nike_apache.ps and terrier_sandhawk.ps. If you can't find them
but can view postscript files, I'll email those to you.

The problem with both designs is the use of mercury switches, flashbulbs
and thermalite. All 3 are hard to find these days, and while the system
does work it's less than 100% reliable. The articles might give you some
ideas on how to convert the model though.
