I hope all goes well and he has the ability to run both, I'd like to think spares for the stingray will be available for a while yet

Parts are availlable at Curtis Youngblood Hobbies. I haven't had any problems getting parts when I need them. So it looks like he can manage more than one business.

I wish him all the success with his businesses.

Did you see the size of the MantaRay (Maxi Stingray) he has built to use for the new business. The photo is from the new business's web site.

Well I guess if Curtis is embracing the word "drone" there's no getting out of it now.

I am trying to figure out why you need a 3D AP rig for doing what his new business is marketing, inspections. Odd... If it only has 4 rotors collective pitch rotors are not going to save it right?

Very True, Will... lose a motor/esc - whatever on a quad, it is going down!
one advantage of using collective is that if one WANTED to, it could be powered by nitro as it has one motor... I suppose the collective could/would be set to positive pitch because, to your point, no need for negative pitch (maybe for inverted inspection of the underside of bridges?? ).

For stability and safety, I would think a Hex or octo would be a better choice...

It would be fun to fly that beast 3d though!

If he has put oneway bearings into the drive line then he could auto it down if there is a power failure, that would require negative pitch. Current CP design and construction of heads and blades is pretty reliable, so you would think a failure of one of those on a professionally maintained craft would be low. It only has the single motor drive, so no redundancy there for motor or ESC but if anyone could auto it Curtis could.

It's also easier to maintain a hover with collective pitch than with fixed pitch.

Experience is something you gain only after you need it.
I wouldn't mind social media so much if it didn't involve people.

Take it up one more order of magnitude and we may be able to take a ride on it.

I've always said his design is by far the most practical for large scale application.
