Can you legally ship potassium nitrate in Europe?
>>913240
yes its usd for curing meat and stuff its not dangerous on its own and blackpowder is hardly tnt or c4
the rules about actually making fuel will fuck you though.

Any questions?
>>913240
You can buy it off Amazon here in the UK.
>>913240
yes, very pure as well. And why would they bother banning it for explosives, if ammonia nitrate and urea nitrate can be made with fertilizer/stumpremover/piss to make more potent explosives instead of potassium nitrate.

there was just a thread on this shit about a month ago.
Solid, liquid or hybrid engine?
>>913295
Ammonium Nitrate was recently reclassified by the EU (I think, definitely by the UK government, think it was an EU wide ban though) so it can't be purchased by consumers, instant cold packs, fertiliser etc is no longer allowed to use it (Actually, I believe it was banned in fertiliser before then due to leeching?) - It can still be bought for making ANFO, with the right licenses, but for the everyday person it's not readily available - as far as I understand.

yeah just wait till they start banning piss because you can make urea nitrate...
A local kook is offering 1000 bucks for launching an object 2 km or higher in the air.
Rotary craft or buoyancy is not allowed.
Is it actually doable from a diy perspective?

Can't regulate a solid engine
Better to make it hybrid, then you can regulate the oxidiser.

>How much rocketry experience do you have?
Zero, and zero budget.
I'm not actually planning to do it myself. It just bothers me that the fucker keeps promoting his stupid challenge that is just out of reach for the common man.
Here is his manifesto, should anyone want to try this themselves.

I'll gladly help with translation.

Guess how I can tell you've never done your own of either.
And technically solids actually can be regulated or even extinguished by venting chamber pressure (the Minuteman III has blowout ports specifically used to terminate thrust on the third stage at the desired instant.
But from a hobbyist perspective, I can't see why you'd ever need such a feature.

Was there no pyrogen on it? Every igniter I've used or made has had a little blob of pyrogen on the end to help things along. A bit of bare glowing bridgewire probably won't cut it.

Well that, I'm not so sure.
Have you kept your engines fairly dry?

This site has some great info. I started making Rcandy in a skillet on the sideburner of a gas BBQ when I was 12. Couldn't afford those stupid Estes engines.
