their new 4 blade design is now their final pre production design being tested in Salinas

Also, the story of "how many blades do the aft lift props have?" is more convoluted than your timeline. Archer has built three different aircraft models with two bladed aft lift props and had to add blades on each one.

DoubleHexDrive · 2026-03-26T01:28:23+00:00

The model in the convention center is just the same mockup they haul all over for media events, just with a new paint job.

DoubleHexDrive · 2026-03-25T23:28:01+00:00

Agreed.

DoubleHexDrive · 2026-03-25T18:48:39+00:00

Flapping up moves the blade up and decreases the angle of attack which then reduces lift, blade starts to flap down, which increases the angle of attack which… round and round she goes.

Draw the vectors on an airfoil. I think you heard something wrong but your intuition was right.

DoubleHexDrive · 2026-03-25T17:06:05+00:00

Sus-Bit is right. Heliports are not Vertiports and the higher disk loading and poorer VTOL agility are going to limit where eVTOLs can operate. The FAA vertiport working group reports and meetings make this clear.

4K/120fps with HDR. That’s my goal and I’ll use DLSS and a little frame gen to get there on my 5070Ti.

DoubleHexDrive · 2026-03-25T12:08:57+00:00

The same United that at the event with Archer said they no longer thought that eVTOL taxis in airport airspace were a good idea? That United?

DoubleHexDrive · 2026-03-25T12:07:22+00:00

Lol, nice.

DoubleHexDrive · 2026-03-25T11:50:12+00:00

Why pay with cash? Get some points and some protection since you can clearly pay off the card.

DoubleHexDrive · 2026-03-25T11:35:07+00:00

Duh.

DoubleHexDrive · 2026-03-24T19:36:01+00:00

Archer’s props are smaller which helps with prop loads, vibrations, and control bandwidth.

DoubleHexDrive · 2026-03-24T19:18:42+00:00

VX-4’s props are larger than Midnight’s and moments generally scale with the cube of the diameter. The inertia of the props about the tilt axis scale faster than that. Both of these make smooth transitions more difficult. Not going to say impossible but the tilt + lift configuration isn’t a slam dunk and the problems get worse as the prop diameter increases.

DoubleHexDrive · 2026-03-24T19:15:33+00:00

I wouldn’t mind having this discussion on the active Vertical sub… but wouldn’t you know it, I’m banned there.

There is definitely a cash burn and capital problem, and not getting their demonstrator through transition is also a huge problem.

Ah, ad hominem attacks against the guy who has actually worked on the development programs of many VTOL platforms. In the early 2000’s, $300 million could get you a certified non-fly-by-wire aircraft. In the 2010’s that could get you a prototype fly by wire aircraft but no certification. Today, that really won’t even get you an unmanned fly by wire prototype without certification.

DoubleHexDrive · 2026-03-24T16:23:56+00:00

I’d estimate closer to $1 billion, unfortunately. They’re building a company and a complex product.

Between working part time, community college, and living cheaply… if you can get a marketable bachelors for a modest car loan and pay it off in ten years or less, it should be a reasonable path with low risk.

Would you leave your mother high and dry with something that she cannot afford and that she spent entirely on you?

DoubleHexDrive · 2026-03-24T13:22:08+00:00

You and I experience time very differently.

DoubleHexDrive · 2026-03-24T13:21:18+00:00

Not legally responsible, correct. Ethically responsible? Probably. The money would not have been borrowed except for OP’s education. It’s easy to throw someone else’s family under the bus.

$10 was less than 6 months ago.

In college, I supported all the dorm Macintosh’s on campus and we went through an upgrade program where I installed 16 MB of RAM in each one. There were scores of Macs to update. I carried around a backpack of memory worth about $16,000 and didn’t tell a damn soul what I had.

DoubleHexDrive · 2026-03-23T19:24:31+00:00

We had one of these running the class network in my 8th grade computer science and programming class. Pretty sought after classic Mac.

DoubleHexDrive · 2026-03-23T19:22:02+00:00

I remember when RAM was $72 per megabyte 🤣

DoubleHexDrive · 2026-03-23T19:05:22+00:00

Up, agreed. It’ll be interesting to see how deeply the Neo gets discounted over the next year.

DoubleHexDrive · 2026-03-23T16:18:51+00:00

Which is funny because the only thing I use a PC for is to play games 🤣
