The Airforce Museum has hundreds of full size aircrafts, including helis. @michael Kranitz, Dallas is not central like Ohio, where you can attract pilots from both coasts.

Consider moving out to late spring? Schools and industries can participate, bigger time gap from the other big event.

Thanks, it's turning out better than expectation, but complexity has gone up.

I think if everything works out, this is as far as I can take this. Next is to create an instruction manual for the DIY version so that customers have the option to purchase this as a kit and build separate components (nose sensor or gun) themselves. Currently very time consuming for me to build...

Thanks, glad you're entertained: )

Nice, looks indestructable like a tank! Plates look very thick, what thickness is it?

Great PR! A little funny to see the term "Accessible Entry" below pictures of helis that cost more than some cars:)

Can you convert this post instead? I'll delete this and add it as a new chapter in the other post, which makes more sense.

29.5 lb flight weight.

Atomize smoke fluid with heated Nichrome wire.

It was a static display project, I've never flown it with the outboard passenger. His seat- the ammo bay door is supported by 2 tension cables, therefore not a rigid platform. I'm afraid he'll be bouncing up and down during flight, too risky.

I tried building my Cobra gun using a similar method years ago. This requires highly precise machining skills because a 1 mm deviation on the gun end will result in a visible rotational wobble on the nozzle end as the barrels spin. Sadly, I lacked this skills. I have since gone to 3d modeling and...

Thanks Mike. The next version will have recoil action.

Thanks Danny. When I first started the Len Mount Cobra 15 years ago, my inability to replicate the highly complex and exposed m197 gun stalled the project for a decade.

Yes.

It's a 3d printed approximation of the Roban Whiskey Cobra, I may print the canopy later to make it look less pissed off😄

This would be a perfect scale head for an Ah-1z Viper.

Beautiful shots and lovely G snake! Who makes this fuselage?

Looks like I'm the only one who followed instructions and posted it within this post. Everyone else violated the rule and posted their pictures separately:)

What do you mean? What I uploaded was 1920 x 1080, higher resolution than specified.

Ah-1F Cobra

There's no longer any restrictions on flying metal blades in the US right?

I think I learned that from you:)

Looks like I'm not the only one who likes rocket igniters:) Do you know that blue color represents inert munitions, used for practice?

If I leave tomorrow, I should arrive by 2023:)

Joe, Go to: ,enter all your parameters (including # of blades, length, etc.) and it will let you know whether your motor/gearing/voltage combo is adequate for safe flying. There's a small subscription fee though:(

Very interesting concept, thanks for the explanation.

Can you explain the thinking behind the design? Why is the main shaft separated? How heavy is this assembly?

Do you intend to add more content to the website? There's virtually no product information there.

I don't quite follow how it works. Does it basically behave like a spacer that prevents blade folding, but loose enough to allow lead/lag?

It's the Solo Shot3.

It seems the tracking isn't that good, especially for the price- $1300 I think.

Congrats Mike, this is a seriously impressive model!

Nice, but I don't think I'd trust the bungee cords to secure the skids though.

I understand native video streaming adds to the server expense. But I think it's a crucial feature to reduce usability friction. Hope you negotiated a good deal with a CDN such as Akamai:) Alternatively, you could allow embedding FB video, where most scale videos are already hosted.

My solution for the tail dragger.

Love the strap solution! While shorter than yours, I too had trouble transporting the Cobra through doorways, steep backyard terrains and flight line. I made a board with skid clips that can be fastened to this collapsible cart. The board also detaches and serves as a locked down base in the SUV....

Uwe Behr, Wow, you FDM printed a landing strut and skid! What size is the heli? How can it be strong enough to support the heli without flexing? The square tube strut is a signature feature of the UH1Y, not easy to make with metal. There's a guy in UK who managed to bend these tubing to perfection.

Manufacturer precutting windows will make the fuse weak, making it susceptible to shipping damage. Hot knife is the ticket, ask Ben Cheng, he is the master of making openings in fiberglass.

What scale? As a scale modeler, that's the first piece of information I need.

Lovely beast! Here's a video on air ambulance that you may find interesting.

Sorry, I'm not convinced it is better to print in rubber. The texture looks like a sponge. Resin print is easier to paint and weather. It's model, there's no need for it to "feel" like rubber especially if it's cosmetic and non functional.

I assume the wheel is non functional right? If so, why the need to print in rubber?

Bravo! Coolest underslung gadget ever! What is it spreading?

Is the wire mesh printed?

Wow, I'm in MN but never knew our DNR flies such a pretty bird: ) Good luck with the build!
