it was a joke. full-o-crap, port-o-john
nevermind.
Ha sorry.
I get it now.

Before you launch this project, give everyone a "heads" up.
I cant stop. :bangpan:
4 motors, all on corners and home-made. Recepie for disaster. One motor not starting with the off-axis thrust will have this flipping across the ground spreading parts and burning motors everywhere. Clusters require you to keep the motors as close together as possible to the center of mass. This way failure of the rocket due to a motor failure at ignition is minimized. This is what needs to be tested over and over, getting 4 sugar/nitrate motors to come up to pressure at the same time without fail.
....good luck with that
'so you think we should cut a whole in the middle and put them in the center?
Thanks

well that approach has worked for about 99.99% of all rockets in the past
I'm staying out of this one. (The mods all go "WHEW")
This guy can't spell, is nowhere near being a "professional," has no experience, obviously doesn't have a clue what he's into.
This should make for some great watching.....
op:
Yeah, a bunch of FX idiots out to blow something up, just what we need around here (if that's really who they are - which I doubt). If they think that TRA, NAR and Tripoli are a waste of time then I think the next best prerequisite for this team would be anvil launching! That ought to give this group some good experience launching heavy objects into the air.
The mods should shut this stupidity down and the sooner the better.
HELLO EVERYONE
I AM WITH ADVANCED AERONAUTICS
I PLEADE YOU TO FINISH READING THIS THREAD AND REPLY, NO MATTER HOW CRAZY OR A BAD IDEA YOU THINK IT IS
WE ARE PLANNING ON MAKING HOME MADE ROCKETS WITH PVC ENGINES
OUR ROCKET PROPELLANT WILL BE MADE OF
KNO3(POTTASIUM NITRATE)
SORBITOL(NATURAL SUGAR)
THEN WE WILL ATTACH 4 OF THESE 7 FT ROCKETS TO A PORT--O-POTTY WHICH WE WILL REINFORCE WITH ALUMINUM
AND HOPEFULLY IT WILL FLY
PLEASE TELL ME ANYTHING YOU HAVE TO SAY ABOUT THIS.

You asked for it.
. . . . . . . . senseless and childish.
I vote to keep this thread open. I find it immensely entertaining. Civilization will survive.
To those it offends, simply stay away from this thread.
Edit: Perhaps most don't realize whom the joke is on?
AeronAdvanced, have you given any consideration to Sodium Bicarbonate/Acetic Acid motors?
NaHCO3
CH3COOH
This would be one way you could avoid having to invite the BATFE and local fire department. It may also avoid your attracting attention of the FBI and CIA.
I do happen to agree with you that the NRA is a lot less than helpful when matters of rocketry are concerned. TRA and even Tripoli have fancy websites with many pictures of rockets. They look rocket oriented to me.

Hey, Well what do you suggest if you dont mind me asking?
And as I have previously wrote we are still doing both thrust and burn rate testing .
And as soon as we get conclusive data up we will post it.
Thanks

If you have to ask, I suspect you have little to no experience building rocket motors. PVC as I understand it does not hold pressure real well and is susceptible to CATO's. I don't think I can discuss anymore about building motors and be within the rules of this forum. Frankly, I don't know a lot more than that anyways.
In your original post you stated that you are going to put 4 ea 7 foot long motors on this porta-potty. That's a lot of thrust for a motor built conventionally. That's something in the O to P range I suspect depending on the diameter of the motors. Four baby P motors? Unless you want to put about 1000 lbs of reinforcement inside, the potty will shred thus endangering your life along with anyone within a half mile radius. I guarantee it. Plus, the FAA is going to want to discuss some matters with you if that really is the size of your motors. Do some research on filing waivers for class 3 rockets. Have fun getting that approved with the FAA. :bangpan: If I am wrong about the size of these motors please specify your intended impulse - preferably in NS.
I have been trying to give you the benefit of the doubt while others were piling on but the more information I see from you the less experienced you appear to be and the more nervous I am about this project. I've been flying rockets since 2005 and am an L2 and also vice prefect of my club and even I wouldn't feel comfortable taking on anything like this. I don't think you understand the enormity of what you are taking on...
Have you thought anything about recovery?
How are you going to calculate your center of pressure?
What is the stability margin?
What is the estimated thrust to weight ratio?
I know I am going to get severely criticized for this but...If someone contacted me and asked to fly a porta potty at one of our launches I would be inclined to say yes. However, there are a slew of questions I would ask (much like the ones above and many many more) before allowing such a flight. And there better be some VERY good answers from a very very experienced flier i.e. "I donno" means no flight. Why is that? It's because people with as little experience as myself know just how many crazy things can go wrong with a "normal" rocket built by very experienced fliers and here you are with zero experience wanting to fly something very big and very scary. Please don't hold it against all of us if we seem dubious of this project.

Recovery Yes I have already mentioned that. Parachute.
Okay, a parachute - but how are you going to deploy it?
I hope you eventually provide better details than that or you will giving credibility to your critics.
-Dave
...
I am not a "noob" Everyone on the launch and production team is proffesionals.
...
Now the engine will probably be N but we are not possitive as we are jsut now starting testing (as of today)
...
For recovery we will have a self deploy full size parachuet put into the assemply, along with a GPS tracker incase we loose sight of it.
Thank You for Replying even if you do think I am an idiot.
