Not to worry.  The only flying this test stand vehicle will do is in pieces.  This seriously reminds me of a low cost infrared camera Indigogo project (muoptics) that several of us in (that) industry watched as they struggled to not be just a scam.  In the end they failed because they were seriously in over their head.  Interestingly enough the founder also owned an animation production company which helped with the money raising at least.  Plenty of frequent video status updates with weak looking lab equipment too.

He's test-fired and flown two other HTP rockets, and I assume they've already pressure tested their tank so I think this test will probably work (produce some thrust) once they actually get their propellant, and I think the Demonstrator 3 will leave its rail

I have been following them a long time, haven't really pulled off anything yet, but I just see it more from the perspective of persistence.

Persistence by means of misleading gullible people is not admirable in my book.

Demonstrator 3 rocket design was updated by moving the aerospike engine reaction chambers on the airframe exterior.

So I ended up investing in ARCA and got to know the team a little bit. I actually have an amazing story to tell, but maybe I will leave that for another day. Don't want to jinx it.

There is always a level of risk like with any other investment but for those of you like me that were already on the fence about it, I just wanted to give you a heads up, and say, now might be a really good time.  In the process of learning how I could go about doing it, I contacted the SEC, the NM securities division and a corporate attorney, and as long as you have a company in New Mexico or you are a NM resident, or foreign citizen, you should be ok to invest even as a non-accredited investor. If you research the rules and regulations, you can probably find this out for yourself. If you do the research, you will find out NM doesn't actually require a company to have a NM address in order to be registered in NM and it's pretty easy to set up your own company nowadays so if you had planned on starting a company anyway, NM might be a good place. That's all I am going to say about that.

Why I decided to go through with it? I did it for these reasons:

1. I love space and small space companies with big dreams. Wish more average people had the opportunity to invest in more of them.

2. An average person typically never gets to invest in a space company at this early of a stage. By the time a company goes to IPO you typically already miss out on the largest returns. Because of that, I saw it as a risk worth taking and once in a lifetime opportunity for me. Even on a small investment, there is the potential of large returns.

3. Even though I grew up in the USA, I was born in Romania, so they're also my countrymen and I just want to support them, and I have followed them for a decade. There probably isn't a single person in Romania that wouldn't call someone crazy if they said, "I want to build a rocket company". It's just not something someone dreams about doing.  Everybody knows starting a rocket company is hard enough in the USA, but in Romania? You pretty much have to be nuts to try it and good luck trying to find any real support. Yet here they are. After more than a decade, still here. Was a smart move to finally move the company to the US though.

4. I didn't know much about investing, but I do have a professional finance background, and I do know it's probably not the worst idea to bet on companies that might be undervalued. I asked myself, how do I think any aerospace company should be worth?  Even the smallest, especially those that have been around for 10 years. I'll leave it at that.

Can't really disclose any more details than that about the investment or ARCA's future plans and I can't give you any investment advice, but if you have any other questions, feel free to PM me and I'll try to answer what I can.

I am also interested in finding people that might be interested in helping me develop a space-related website and bouncing off ideas.

With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

When asked the question, Arca's response to that was:

Just a teaser. 😉 We will release details about it in the future

..so I guess only time will tell exactly what that means.

You're not a rocket scientist worth their salt unless you dream big! :-) Surprised they are not using a common bulkhead, as you get significant mass savings there. With HTP/RP-1 a single wall can be used, so its not that expensive.

Did you read this thread before making that investment?
If so, what gave you the confidence in their ability to execute, in spite of the skepticism shown here?

The only real question about this ARCA bunch is about Dmitru Popescu: how smart is he really?  Is he a testament to the Dunning-Kruger effect, or more like the unreformed Frank Abagnale when he was a kid, clever enough to think he could actually get away with the game he was playing.

As for the employees there's a similar but slightly different question:  Are they sincere dreamers in over their head or are are they fellow schemers in on the game?

Those remain questions we can pose, but one thing we can affirm with a fair degree of certitude:  this is not a serious space flight operation.  Whether they are actually aware of it is a matter of conjecture.

Oh yes, I absolutely understand the skepticism. Like I said, I have been following ARCA for over a decade. I have been at times their biggest critic. I have a great story to tell one day of why I basically had to invest but like I said, now is not the time. I don't want to count my chickens before they hatch so I am not going to say everything now. One of the biggest problems is a culture barrier, where ARCA is going to have to slowly adjust to correctly presenting themselves in order not to hurt their image. And I think they have shown that recently. So they came out maybe a bit iffy at times in the past with some of the videos and products, but that will fix itself in time. It's definitely because of that, and not because of anything else.

If you are talking about execution as in the Demonstrator 3, I'm crossing my fingers like any other ARCA fan, sure. That's the thing, though, isn't it? Musk doesn't execute. He hires the right people to do that for him and to learn from them. It's the SpaceX engineers that are the unsung heroes. He dreams up things, he had the money, they execute and in turn teach him things. Luckily ARCA won't have to compete for everyone else's engineers since their tech is completely different and hopefully funding will prove successful in order to hire the right people.  But really, the CEO's job is not typically to get on your hands and knees and sweat making tanks, it's to plan a path and lead your team to follow your vision.

 If that's the type of execution we are talking about then, yeah I think Dumitru has proven he has what it takes to overcome difficulties, even start over, completely change directions when it was the right thing to do, and truly started something from 0. I think those are all important qualities. And that is really a big one. Whether a CEO is willing to listen to everyone's opinions, and take everything into consideration, and make changes for the better of the company and I can tell you he does. All I know is I honestly can't think of any other rocket manufacturer that has really started from 0. If he can do that and go from 0 to a $20 million company under the most extreme of circumstances, it's not that big of a leap of faith to believe he can do a lot better in the USA.

The truth is I would have invested in most of them, but I couldn't invest in SpaceX, I couldn't invest in RocketLab, I probably can't invest in a lot of the other ones I like, like Accion. But I could invest in ARCA and I felt I had to invest in ARCA. That makes it pretty easy to decide.

I also recently found out they share the same vision I do about the most efficient ways to launch rockets which emboldened my decision but that's all I can say about that. Sometimes cool things lurk in shadows...

I am not familiar with that but I must say you are the first person I hear refer to a rocket engine turbo pump as a trivial matter.
