Hey, i'm a beginner in the rocketry feild and haven't messed with much
more than an estess rocket that ran an 1/4 A rocket engines. I know
this sounds stupid but I'd really like to get a complete hybrid rocket
kit to "play" with. I need something pretty basic with minor assembley,
no hard to find parts, jus about eerything included, under $100 (sound
to pickey?). If a kit like this exists i would like a like a link to
the site where sell them. Please remember that I am beginner, if this
is a stupid question, wel then, sorry for wasting you time.
thanks in advance

There are no stupid questions, save the unasked ones. There is one
thing that nobody's mentioned. You're about to get in over your head for
your experience level and so I would suggest taking your time on this
project. Also, as was mentioned, I doubt you can put a flight worthy kit
together for under $100. Besides the kit you'll have to be getting
electronics for your chutes' deployment (and black powder/Pyrodex as
well as a means to ignite it). And if your local club doesn't have the
ground support equiptment you'll need, guess who gets to foot THAT bill
too? I'd say $300 might be a more realistic minimum, depending on the
kit, electronics, and motor you decide to buy. I'm not trying to daunt
you, just mentioning what I know you'll need in place. Better to know
ahead of time rather than finding out the hard way after you've taken
Certainly I hope you're dealing with a club where there's folks with
hybrid experience. Going solo on this could be something for the Darwin
Awards. Don't rush things, have fun on the journey.......and take out a
bank loan to finance it! :-)
I'm just starting to use the RATTWorks H70 in my BSD Horizon 4".
The URL is http://www.bsdrocketry.com/4%20Horizon.htm and the kit is
I've been getting excellent hybrid support from Doug Pratt at
http://www.pratthobbies.com/ and he has that motor for about $60. He
has a lot of "getting started" info about hybrids on his web site.
You'll have to use electronic ejection as hybrids don't incorporate an
ejection charge. That alone will eat up most of your $100.
Does your local club fly hybrids? If not you're looking at getting a
tank and plumbing. Doug has his mini-tanker combo
http://www.pratthobbies.com/proddetail.asp?prod=RTLS%2DMTC for $195.
You can use two channels of your club's launch controller to run it.
Going from Estes to Hybrids is quite a jump. You may want to certify level 1
on a regular solid fueled H motor first in order to get some experience with
the bigger rockets. Since hybrid engines have no delay or ejection charge,
you'll also need to learn how to use electronic devices like altimeters and
accelerometers in order properly to deploy the parachute.
Not trying to discourage you, but by progressing in small steps, you'll save
yourself much disappointment and possibly prevent expensive and catastrophic
PML and LOC/Precision both sell hybrid-ready kits. I believe LOC's kits
are all larger and more expensive, designed for 54mm HyperTEK motors.
PML has some that they've designed with the SkyRipper hybrids in mind,
which fly quite well on 38mm hybrids.
If you want an inexpensive electronics setup to start with, consider the
Magnetic Apogee Detector kit from Aerocon Systems
(http://www.aeroconsystems.com ). It requires some soldering skills, but
for a bit more may be purchased fully assembled.
I fly my RATTWorks H70 and my SkyRipper 38mm hybrids with the MAD and it
works like a charm.
How similar / different is this from the one designed by RobG? I ordered
Rob's version, and it was all surface mount parts. WAY beyond my Heathkit
level assembly skills, but a fellow NIRA member assembled it for me.

We need to ensure that actions by our government uphold the
principles of a democratic society, accountable government and
international law, and that all decisions are taken in a manner
consistent with the Constitution.
It is the one designed by Rob Galejs; actually, it's a slightly updated
version from the one I originally purchased. I think it now has a
continuity light added to it.
My soldering skills also qualify as HeathKit level, and I didn't have
any trouble assembling it. Just take your time and don't open any part
until you need it.
On my first attempt to launch a hybrid I had a leaky vent line that
pressurized the airframe. The payload bay fell off. Very embarrassing.
A MAD would have triggered. Of course, you can come up with lots of
scenarios that cause "premature eject-ulation." 8)
Another option might be a G-triggered timer like
is slightly cheaper than an altimeter.
Ask around at your club. Maybe someone wants to sell a used altimeter?
