Looking good there, maduncle, and exquisite work as ever, skinznhydez!

It's the season for rocket packs- I saw one at Whitby Goth weekend, on the back of a Rocketeer!

[Maets]

Second test flight of rocket pack.  Directional fin added to helmet for better flight control.

 

[maduncle]

Wow Maets - that looks like 'altitude with attitude' (the rocketeers guild slogan).

And no discernable exhaust either - looks like a clean green form of propulsion you are using there.

[Captain Braid]

Thanks for all great feedback on my jetpack!
I would love to join in on the race, but the one I made was a commission for someone. So unfortunately its not in my possession. He actually is a photographer in the states and just sent me some pics.

Highly Impressive, Skinznhydez, highly impressive indeed.

@Maets; My hats off to you sir.

Test fire video of Maets Rocket Pack Two. Unit has been clamped to post to hold it in place during test.  Enjoy!

Now that's what I'm talking about.   whooo hooo that is cool!

[Capt. Dirigible]

That is very impressive, Maets, very impressive indeed.

[Maets]

Thanks!  I have been having some fun with all of this, as you can see.

[The Squire]

OK, Maets, now I feel the need to build! Most exquisite, sir.

[Birdnest]

Good Show, Sir.

Quite a spectacular assembly.

[maduncle]

Crikey!

That is fantastic Maets, what is the power source.

[Maets]

That is fantastic Maets, what is the power source.

The real key to the effect was building the unit with full and open connections. It is built as if it could actually work. I will probably go back and modify my first unit in the same way.  Just a couple of blockages I need to remove.
If you want the full secret:

The "steam" comes from an external source connected via the control hose.  Your earlier observation of "cool" was close, it is actually cold.  I connected a CO2 fire extingusher to the unit.  What you see is the liquid CO2 being ejected when the handle is squeezed.  Not practical for walking around, but could be used on stage, or in a parade or somewhere when the CO2 tank can be hidden.

had a test flight today in Chepstow for the South Wales Argus, they were very impressed

This makes me wonder about the practicality of building ones rocket pack around a small extinguisher, which you could swap out once it's expended...

There you go.... that's using the old noodle.  Put a trap door on the bottom of a brass tank for the extinguisher to sit in.

[Maets]

Available volume and weight are the problem with building the unit into the rocket pack.  You don't get a whole lot from the CO2.  To get the visual effect you have to be sure to be pulling the liquid CO2 from the tank and not just the gas.  You get the great sound either way.

Alright, definitely going to take a look at a couple different extinguishers when I get to work tomorrow and see if it looks like the nozzle can be separated without activating the whole thing... I'm hoping it's set up similar to the disposable propane bottles one would buy for a camp stove, with a plunger in the middle, which in this case is depressed by the nozzle being screwed on, and then the nozzle has it's own valve in it... *smells smoke* uh, oh... I've really got the gears grinding now!

how were you able to separate them?

-Jake

[Maets]

Any fire extinguisher I have ever seen (and I have seen thousands) is filled (and emptied) through the valve.  They are not made like the propane tanks.  I use the handle/valve to send the CO2 down the hose connected to the rocket pack. The hose can easily be screwed on and off or you can use a quick disconnect fitting, but you'll have to use the valve attached to the tank.  

Fire extinguishers draw from the bottom of the tank, thus pulling liquid.  A CO2 tank for welding or putting bubbles in your soda draws from the top.  Use that type of tank upside down to pull liquid and thus the appearance of steam.

Paintball cylinders probably are the best to use for a built in gas supply.

There is another approach to producing CO2 smoke.  Vinegar and baking soda mixed together give quite a display.

I'll throw my Flying Helmet into the ring with this one.

WIP at the moment.


Maduncle, Add me to the rosta. if you please, but she's getting the '00' race number if that's OK.

'Team Dastardly' strikes again.

Wow - that is looking quite deadly Cornelius, the next number to be issued is 5, do you wish to claim it?

So far I have issued:

#1 - Maets
#2 - Herr Doktor
#3 - maduncle
#4 - Helga Von Flam

[Maets]

Welcome Dr. Quack to the ?

Is there an official name for the Rocket Guild or is Rocket Guild the official name?
Some thoughts on names:
R³
Royal Rocket Racers
Rocket Racer Regiment
Rocket Racing Recyclers

R⁴
Royal Rocket Racing Regiment
Regiment of Royal Rocket Racers

Mad Uncles motto seems perfect to me: "altitude with attitude"
Any thoughts?

[Maets]

Or something different
Society of Crazy Rocket Air Pilots  (SCRAP)

[Mr Addams]

I still like the Topic heading as a group name.
"The Rocket Pack Collective"

[Dr cornelius quack]

The Rocket Aviators Club

Look, Someones already started making badges.

Maduncle, I'll stick with '00' if you don't mind. The Dick Dastardly motif opens up lots of scope for decorative embellishments and I've always wanted  a small, sniggering sidekick.

[maduncle]

I am pretty keen on keeping the title as 'The Rocket Pack Collective'.

I think it sounds good.
