Model rockets

[Tank]

Hoping that someone can help me.

Im looking for someone who is into high power model rockets.

I have few questions about engines and it would be great to have someone (other than the vendor) to get some info off.

For those who arnt - they are good for 10,000 ft - break the speed of sound and a simply bloody awesome.

Rocket science huh?

[Marmoot]

fed up with the government and decide to blow something up?
Or just planning to sell some to middle east?

... they are good for 10,000 ft - break the speed of sound ...


How the hell can that be legal?? You could bombard Israel from Gaza with those babies. You could have a good go at hitting a plane coming in to land.
Watch out the Israeli Defence Force doesn't bomb your neighbourhood if they find you have rockets on the premises.

More information please, they sound cool. What brand, who makes them, where can I get some??

[Tank]

yup. Teaching it to my son - we just want to do BIGGER, rockets with MORE POWER, lots and lots and lots of noise and power. Did I mention power.

We are wondering if we can get one to over 760 MPH. We recon that we can. btw - thats over 350 meters a second.
and thats ummmm really fast.

Honestly what are you trying to achieve? :lol: Wanna blow up something up? lol
The details sound lethal when used dangerously

Is it legal, is it safe? - yes indeed.

in fact there has never been a person hurt in 'proper' sport rocketry.

Here is a puppy that is good for 10,000 ft and Mach 1+ (yeah baby) and it ain't small.

btw pics are not me.

You do have to get clearance from the aviation authorities and get certified be be legal to buy the motors (the expensive bit).

From Auckland the closest high power launch site is Taupri.

Can you put a hamster on top???

I'm on Youtube now, there are heaps of videos on there, fascinating!
Tank, have you read or seen Rocket Boys? Made into the film October Sky . I'm sure you have, it'd be a must-read for rocket enthusiasts.

Actually I havnt - must do tho'.

Im new at this and still learning. Its 1/2 model making, 1/2 luck and 1/2 maths. I think I have the maths part sorted.

Currently working on horizontal launching and gps guidance - coz thats gotta be a laugh.

Thats just stupid!





























it ruins the areodynamics. You have to put them in the cargo bay right above the ejection charge.

[onearmedbandit]

Looks cool. But how long do you get enjoyment from them for. I mean, like watch the blast off, a few seconds of flight, and then it's gone?

ummm do they get parachutes... or do we need to call some animal activist or something... :devil2: :lol:


p/t

[Usarka]

What are they fuelled with and what's the burn mechanism?

It's probably got something to do with the planning, building, clean-up, post-flight analysis, then back to the planning again.

You have to remember that they have parachutes and can be reused. So you get to use them multiple times.

And its seriously fun time - I do it with my son and we enjoy the time together. We are only on our second rocket (lost the 1st), but already we are eyeing up the bigger ones......mahwhahahaha

Where do you buy from?
I used to make home made stuff - but most failed and exploded (was still worth it).
Its kinda what got me into making bombs when i was a kid....failed rockets.
Ironic how a bad rocket makes a good bomb, and a bad bomb makes a good rocket.

You can get the small kits from hobby city - they are cheap and fun, but still go a VERY long way VERY fast.

Bigger ones can be got from rockets.co.nz - possibly the worlds worst website. or from the US. Im guessing engines will need to be purchased from NZ as shipping them would be problematic.

I do a rocketry course at school where I teach, also use October Sky as a year 9 visual text and combine it with practical elements.

The B class rocket motors will launch a small rocket 1000-1500ft into the sky no problem at a staggering rate of knots. When I launch, have to watch the local airspace as they can go high enough to hit low flying planes! :innocent:

The kids love watching the launch with the smoke and noise and then they all crane their heads to watch it accelerate away! When the parachute pop out on the kevlar string and wafts down to earth, you can see their smiles widen! :yes:

Bloody good fun is rocketry... I got the set up for several rockets and the handcontroller/launch pad etc for launching them!

And yes, I do so want to launch rockets that can go further! :devil2:

There was a guy in the paper recently who was building a rocket to break the NZ (and I think, the world) height records. His first attempt went OK, but the GPS carked it so he didn't retrieve it to verify the altitude achieved. I worked with a guy in Chch who belonged to the rocket club there, but they were smaller ones that were nowhere near as big as the ones pictured.

The way the scale works is that B is twice the power of A, C is twice the power of B, D is twice the power of C etc etc etc

We did 'B''s as a starter. Moved onto 'D's in a day.

Currently looking at getting a kit and firing it off with I's or J's. :woohoo:

If you have the targeting package, I'll go and get the co-ordinates for the beehive...





Hello to all the law enforcement community tuning in to this post:wavey:

[tri boy]

Taupiri, (just sth of Huntly) is a recognised launch zone.
Must pop up there one day on a club launch day.

Mate, now helen will ban them..... :spanking:

[CookMySock]

I made up some propellant using KNO3 and Icing sugar. Worked real good. Found some clay for nozzles from the local welldriller. Laminate/roll tubes out of paper.

Good fun. Haven't done any high altitude stuff yet.

Most definately. We cannot allow anyone to have fun, can we.
How can Labour tax this recreational activity?:shit:
