Holey smokes these are fast, especially with the traditional props.

That was cool. Yep it's unbelievably fast. Wow. Impressive control the operator has.
 
The newer toroidal props are more efficient, but weigh more so do slow down acceleration (of the motor) slightly.
They are made for boat propellers too.

Speaking of fast...
...have you watched any of the Drone Racing League (DRL) competitions?
There is a season and it is covered on one of the cable TV channels.

There are a lot of very skilled FPV (First Person View) drone pilots out there.

Wow, a lot of skill there. I noticed the 8-blade props were significantly quieter and seemed faster. I've read a couple of articles that mention the toroidal props are quieter, but they're only talking about the 2-blade props, not a 3-bladed prop as in the video.
Who out there in BARFland has experience with toroidals?
 
How does one get into POV drone running? Where can one even practice it? It SEEMS like it might be fun.
 
Interesting. I had just heard about these toroidal props recently when a YT video came up in my recommended feed.

Here, the guy printed one of them to test out as a PC fan. Seems like it has less high-frequency noise in his testing, which might be why it's perceived as quieter.

Since I can never get the YT tags to work, here's the link: https://youtu.be/4ImeOKgD_Dw

The toroidal props in the video were really quickly modeled, not optimized or anything and not balanced. A pretty impressive showing imo.

The pilot has some serious skill!
 
How many people here fly drones? I haven't seen many posts about it.

Last time I recall a discussion there was someone who was working to pollinate trees with drones... Speaking of which, I was contacted by a friend today who is looking for someone with an ag sprayer drone to work on a special project. It's legit and really interesting.
 
BARFer carriesanaxe was involved with a company doing drone pollination.
 
I suddenly became uninterested in POV drones because it seems all you really need are the goggles, controller, and simulation. At that point it's just VR video game.

I had seen that, and I think he said he wanted to buy a prop for his dad's boat, but it was five grand... That makes me want to 3D print a prop and then fiberglass the surface, for my little boat.

As far as FPV drone flying...

The "sport/activity" is under threat of being ended by new FAA drone rules that went into effect last September.

Specific to FPV drone pilots is rule # 8 regarding keeping the drone in visual site. Most FPV drone pilots like flying obstacle type courses which often includes losing visual site of the drone. An FAA violation.


New Drone Laws

General Drone Flying Rules For All Drone Pilots

These are some of the most common rules when flying drones in the U.S. but there may be additional regulations in certain states. If you’re unsure whether you need a permit, check out our guide to flying drones in the U. S.

The following regulations are applicable for both commercial and non-commercial (recreational) drone pilots.

1. You must fly your drone at or below 400 feet.

2. Avoid interfering with law enforcement or emergency response operations.

3. All drones must be registered and should not weigh more than 55 pounds.

4. You must register each drone at the FAADroneZone, the registration costs $5 and is valid for 3 years.

5. Drones registered under section 107 may be used for both commercial and recreational flights.
But drones registered under Exception for Recreational Flyers are not permitted for Part 107 operations.

6. Use B4UFLY Mobile App – the safety app from the FAA, which uses your GPS location to deliver up-to-date information about flight regulations and airspace restrictions.

7. You must be aware of No Drone Zones.

8. You must fly within the visual line of sight so that you or the observer can see the drone at all times.

9. You must move aside and let manned aircraft pass – without interfering in its path.

Drone Regulations for Recreational Pilots

Here are the rules for flying drones for recreational purposes:

1. If you want to fly drones for fun in the USA, you need to take the TRUST exam (The Recreational UAS Safety Test).

2. You don’t have to register your drone if it weighs less than 250 grams.

3. You must follow the safety guidelines of a CBO (Community Based Organization) like AMA – The Academy of Modern Aeronautics.

4. You must fly your drone in Class G (uncontrolled) airspace.

5. You need to have airspace authorization if you want to fly in Class B, C, D or E controlled airspace.

There are some exceptions for recreational UAV operators. You can read Advisory Circular 91-57B for more information.

UAS Regulations For Commercial Drone Pilots

Following are the rules for flying drones for non-recreational purposes:

1. To fly drones commercially you need a Remote Pilot Certificate – Part 107 license.

2. You can not fly your drone at a speed of more than 100 MPH.

3. To become an FAA-Certified drone pilot you must be at least 16 years old.

4. You must be able to understand, read, write, and speak English.

5. You must be mentally and physically able to operate a UAV safely.

6. Before signing up for the knowledge test, create an IACRA (Integrated Airman Certification and Rating Application) profile.

7. You must be aware of airspace restrictions and avoid flying drones, particularly near airports. Make sure to not put anyone or any other aircraft at risk.

8. Commercial UAV pilots can fly drones at night, over people and moving vehicles without a waiver under Part 107 as long as the rules are followed. You must have airspace authorization for night operations.

That was some bad ass drones... and hella fast!!! :wow

We had several drone companies and our own drone pilot on our Coastal ride. I learned a bit about them and the restrictions.

This one bit us several times. It was a bummer too. Some places only had height restrictions. Ok to fly below 100 ft but not above etc.

Flying next to the Golden Gate Bridge required a permit through State Parks. Costs some moola and takes awhile to get. It is interesting that the boundries are enforced automatically. Our pilot for instance ran into a no go wall about half way out on the Crescent City Pier. The drone literally would not go any further whether he want to or not. Pretty amazing.

I would like to fly one, but feel to be awesome would take some time.

It just doesn't seem worth it. FPV means you wear goggles so you can't even see the drone when it's in front of your face. WTF? Oh, but you can have an observer? What qualifies as an observer, and what could they possibly do when considering 100+ MPH drones?
