I'm way out here in the desert and they don;t care what is launched, why at
a launch at the Mojave space port last year they let a guy fly a all metal
mid enegined (Estes E engine) fly at the special day launch they had for
local kids and that rocket was all metal soda cans, body tube, fins, the
whole thing metal, so me flying an estes alpha with a old chevc windowmaker
C engine which for it's age still worked as it should was no big deal. And
that's why I've managed to get the local service people to includ a aero
park in their plans, it'll be set up for rmodel rockets, rc plans, control
lines planes. It might be another 5 years before it's built but it's in the
works and I have submitted a plan for it too.
They allow aero fireworks in Kern county.
In the title, which is the part of the document where you in a few
words try to summarize the intent of a (much) longer document so that
people who are interested can read it.
The term "decertified" is correctly used elsewhere in the document.
Did you read it?
That's because NFPA doesn't require motors to be decertified because of
age. That's something that NAR does. Members of NAR have asked that we
figure out if that's necessary in this day in age. We now have a
controlled R&D program to do just that.
Um, people like you, apparenlty.
You can submit it all you want. You won't be correct. They can not only
fire them, they can fly them, IF they've complied with conditions
outlined in that long document you apparently didn't read.
Because, if tney comply with those requirements, they'll be flying
OK, so you're all for it, you just think it's illegal? Or, you're all
for it, you just don't like the NAR making it legal? Or what, exactly?

Terry, what part of this don't you understand:
You can submit it all you want. You won't be correct. They can not
only fire them, they can fly them, IF they've complied with
conditions outlined in that long document you apparently didn't
Because, IF THEY COMPLY WITH THOSE REQUIREMENTS, THEY'LL BE FLYING
(replace "spambait" with "merlinus" to respond directly to me)
evidently I don't understand alot of it. Lets see if I got this right. If a
NAR section, follows all the requirements of the SCCCP program, then model
rocket motors that have been preveiously decertfied, now become "certifed"
SO basically following all of the requirements of the SCCCP just changes the
status of decertfied model rocket motor to certfied once again? Hmm thats
an intresting concept.
And theres nothing in NFPA that I can find that says a "recognized testing
organization" such as the NAR can't reverse itself on prior decertfications.
DO I understand now?

There is no need to impress small children with a large or loud rocket. They
thrilled with any small or medium model rocket that launches and recovers safely.
Many adults make the mistake of thinking they need to "impress" kids or put on a

requires certified motors or require insurance this is a No No.
Next, a flying saucer is extremely prone to weathercocking and with a pitifully
motor like the FSI F7, it will arc over and hit the ground (or a child's face)
thrusting. Then several seconds later the ejection charge will go off. if it
grass, that starts a fire. if it hit a child in the face, then the rest of the
walk over to see what happened or the adult who runs over to help the injured
then get hit by the flaming ejection charge.
Saucers need the correct thrust motor to fly safely and they prefer plugged
motors or a
very short delay to eject at a safe altitude.

My thanks to the group for the advice....I guess I'll have to rethink
the saucer idea, guess I got caught up in the coolness of the idea.
I'll stick with the tried and true...Chrome Dome, Blue Ninja, etc. I
still might build a saucer, but I'll stick with the one that flies on a
plugged A10 mini motor. (My original idea before I was struck with the
thought of trying for altitude at the same time.)
I'm still intrigued by the idea of flying a saucer with an F7, but I'll
leave that for my own personal testing and fun and fly it at my normal
(and isolated) launch area. Thanks much for the advice. (Special note
to Mr. Kaplow...I followed your advice from one of my previous postings
and am building my Onyx with yellow glue...haven't flow it yet but I'll
let the group know how it turns out. The rocket is now in the final
finishing stages and should be ready to fly within a week. Should look
kind of neat...it's painted dark orange with a reflective gold nose
cone and fins to assist in tracking the rocket during descent.)
One of the best demo rockets is the Estes "Fat Boy". It has a little
size to it and can be flown on a range of motors; from a short delay B
motor, for a small school yard, to a monstrous C motor depending on the
school yard size.
A member of our club tried to fly an Applewhite saucer on an old Aerotech
F14 the other day. After the thurst spike, the rocket fell to the ground,
still thrusting. I would think an F7 which is half the thrust and half the
total impulse, and which can barely lift itself, would have a much worse
time with a high drag saucer.
I say don't waste the motor on that. Find a small, minimum diameter rocket
for it and let it do its thing.
<Cluster those F7's!
There are 3 photos of a cluster of 4 F7s I made in the 70's, it worked
great the first time it flew with 3 FSI F7s and a center Enerjet F-67.
But when I flew it with 4 F7s it went unstable.
I'm with Dave...
Wrapping up a LOC Viper IV project (pretty healthy stability margin)
with some additional side pods mounts to burn up accumulated odds &
ends... Will later finish the debate how to be done with all the 10.5
mm bp motors I've got.
Dave - Great pics! The shot of getting stuck at Lucerne reminded me
of burying the rental car up to it's axle at Hemet. Even after trips
to the car wash, the car never quite drove the same again!!! Andy
Woerner pulled us out of the mess that afternoon. Great guy!
Doing a demo with ancient and likely highly unreliable motors that in their
best form require skill and luck to fly reliably, is NOT a very smart idea.
Think about it.
Ask Don Carter about what can happen when one of these catos. How far away
do you plan to locate these Cubs? Just what they need, 40-50 gram chunks of
flaming BP flying around the place.
Burn them off somewhere safe and remote, and away from other people's kids
is my advice.
