(PR) New "econo" hybrid launch system from Pratt Hobbies

"Whippets are small canisters of (N2O) nitrous oxide. The "whippet" cartridges look like standard CO2 cartridges, and are used to charge commercial cream whippers. When used not for it's intended purpose as in this reference, the gas is released from the canister into a balloon with a 'cracker' and then inhaled."

Anyone happen to know what sort of pressure the N20 is stored at in those cartridges?

As long as it's certified so I can fly it at NAR launches, I'm interested.

Pressure inside the charger is about 65 bar at room temperature. Mark McGill iSi North America Executive Chef/ Web Master Mark snipped-for-privacy@MSN.com

Don't think so...

Wow, didn't expect it to be so high. That's quite impressive, I can see why they're appealing for small hybrids. Are they available in any larger sizes?

cartridge.

Bingo. Pratt Hobbies plans to offer the Deepsky Afterburner to the American market. I got some to test last week. Impressive and sophisticated.

That's phunnie!

Why, BP is mostly available in most free states, mostly.

Pyro actuators work well and are time proven, even in professional sounding rockets.

Doug has Pyrodex canisters for those that have hardships in BP acquisition..

"I hear by bless this motor in the name of TMT..." I think that will be happening real quick here Bob for those motors.

Bob, NAR launches are fun, and some are even competitive.

However,

You need to get out sometime and try a few non NAR launches and expand your horizions.
