drones.....

The friendliest place on the web for anyone who enjoys boating.
If you have answers, please help by responding to the unanswered posts.
I had a Mavic Mini that I always attached a piece of styrofoam at the top so that it would not sink if it hit the water. During one flight, the drone was hovering about 10 feet above the water and suddenly started descending on its own. It hit the water but remained afloat and I was able to retrieve it and send it back to DJI. Since I had the insurance, they sent me a new drone.
 
Drone recommendations, and a couple of clarifications

I have owned, or used in my classroom (I taught high school aviation)

DJI Phantom 4 - By far, my favorite. It is big, and clunky to carry around but can fight through heavy winds and gives you a built-in frame to grab if you are landing on a boat. Every time I see someone try to catch one of the smaller drones I tighten up my bottom a bit because I have seen what those small blades can do to a hand or arm. DJI doesn't make these anymore, so you have to get them 2nd hand. I have bought a couple off of ebay with good luck but I prefer to buy them from facebook marketplace so we can do a test flight. The batteries for this one, and all DJI drones I have use, are smart batteries (and expensive). Check the batteries for swelling before you buy, if they start to swell consider them trash and buy new ones. I have purchased off-brand batteries for my Phantom 4s with no problem

DJI Mavic Pro - My drone of choice is a Mavic Pro. They came out in 2016. The Mavic Pro has 4K video and a pretty good flight time. The reason I choose this one over the Phantom 4 is it's size. It folds down to a camera case size. It has been replaced by the Mavic 2 series, but I just didn't see the benefit in upgrading. There is a Mavic 3 out that has double the flight time (almost), but until the Mavic Pro dies I see no reason to upgrade.

DJI Mavic Air - Great drone, but lighter than the Mavics. While that seems like a benefit I am usually flying in wind so I prefer the heft of the Mavic Pro. Very responsive, but if you don't require a smaller drone I would look at the mavic Pro.

DJI Mini - These are small and great for no-wind environments. With any wind, they are pretty squirrely and burn through their battery quickly trying to stabilize. Most people I know that buy these end up buying a different drone because these are more toy than tool.

Parrot - They made a LOT of Bebop and Bebop 2 drones. These are fun to fly but the cameras are weak, and the drones have a history of just falling out of the sky. 2 of ours just died and fell, so I sold all of them. Parrot sells higher end drones now, I don't have any experience with them. Don't get sucked into refurb deals on Bebop 2s, run away.

The best way to learn to fly in challenging environments is to get a cheap drone with blade guards, then fly it in a room and learn to kiss the walls. have the drone face away from you, then fly to just barely touch each of the walls in the room, then spin the drone 90 degrees, and do it with the forward perspective facing to your right, then spin it 90 degrees and do it with the drone facing you, then spin it 90.............You need to get to the point where it is natural to visualize which way the drone is pointing and how you need to shift your controls based on drone positioning.

Don't practice with micro drones, they are way too squirrely.

I buy these for my students. https://www.amazon.com/Holy-Stone-W...mzn1.fos.006c50ae-5d4c-4777-9bc0-4513d670b6bc The cameras suck but they are tough drones that are great for learning to kiss walls.

Once you are done kissing walls, start working on depth perception. Go to a place with a lot of light poles (we use the school parking lot) and practice going around light poles in the distance. then spin it 90 degrees, and do it again.

Also, never rely on using your phone as a controller. Too many problems. You phone will connect to most controllers (with a wire), which is great. But dont fly with phone alone.

Don't listen to people telling you about regulations concerning drones. They are usually only 50% right. The only real authority is the faa, and the message is still a bit muddy. Their site is nowhere as friendly as it should but you can go here and get the info you need https://www.faa.gov/uas/getting_started

You can fly drones under 55 pounds without any big problems. If the drone is over 250 grams you need to register the drone. Registration is simple and costs $5 for 3 years. There are lot of trick sites that look official but aren't really faa registration, go here https://www.faa.gov/uas/getting_started/register_drone

Lastly, everything above is for recreational flyers. There is an app called b4ufly that will help you understand where you can fly.

If you intend to monetize the flight in any way, you need to get what is called a part 107 certification. Even if you put something on youtube that is eventually monetized you have broken a federal law (FAA) if you are not a commercial drone pilot (107 certified). The 107 test is fairly tough, about 60% of what you need for your written private pilots test. If you are interested in getting one reach out, I am happy to share some resources with you to help you pass.

Any questions, feel free to reach out.
 
Drones can be a lot of fun. I took this vid during 2020 Covid when this Island was closed to foot access. SBI a tough one to get on in general, even on good days with low wind and swell. 2 min video:

Launching drone from moving boat - how to avoid a very expensive mistake

I will offer one important piece of advice, gained through the school of hard knocks:

Most drones will hover stationary in the absence of any control input. For that reason make sure your drone is clear of any obstacles on the boat when you are launching it. Best is to launch by hand, well above rails or obstructions towards the stern. As soon as you launch the drone from a moving boat it will want to stay stationary, which means it will be moving backwards relative to a boat moving forwards.

I launched my drone off the rear deck of my flybridge a few years ago while the boat was moving very slowly ( 3 +/- knots). As soon as the drone lifted off the deck it appeared to zip towards the rear where it quickly impacted my handrail and then plunked into the drink, never to be seen again. In the blink of an eye the drone was gone. I didn't immediately understand what had happened but afterwards it was obvious. The drone didn't fly into the rail - The drone stayed stationary and the rail moved into the drone.

A safer approach is to make sure the boat is stationary when launching, then go back to cruise after the drone is safely in the air.

An expensive mistake for sure. Hopefully this prevents others from having a similar experience.

In terms of retrieving the drone at the end of the flight, I'm sure there's lots of good advice in this thread. We always make sure the boat is stationary before attempting this, but I've seen people hand-catch and use nets, etc.

Interesting! I had always heard that doing something like that altered the flight characteristics of smaller drones.

I have not flown or owned a Mini, but I have owned a Mavic Pro and a Mini 3 Pro. I will say that the only advantage of the Mavic Pro is cargo capacity. The Mini 3 Pro is better in every other way. It is considerably lighter and works harder in gusty conditions, nevertheless the flight time is longer (way longer with the large battery) and the images higher quality and better stabilized. Also the Mavic, weighting about a pound and a half, has many more restrictions flying in most foreign jurisdictions (for example Canada). In the US, it requires registration, marking, and a beacon.
 
I tried to launch my Mavic Mini from the deck whilst underway. It rose and flew off backwards, hit the handrail and tumbled overboard. Fortunately it landed on the swim platform with the battery coming out and landing in the dinghy.
Launch with it on your hand with a clear line of sight to the stern.

The piece of styrofoam attached to the top of the drone did slightly affect the flying characteristics of the Mavic Mini in windy conditions but the Mavic Mini is not good in windy conditions anyway. I originally attached a plastic landing gear with 2 round foam floats on the bottom and this made the drone almost uncontrollable so I shaped a piece of styrofoam to be as aerodynamic as possible and used rubber bands to attach it to the drone. It is just enough to keep the drone afloat but not so big that it interferes with the props or severely changes the flight characteristics. Because I like the portability of the mini drones, my next drone will be a Mini 3Pro which has more powerful motors to make flying in windy conditions a little easier to deal with.
 
I've flown a Mavic Pro for around five years now. I was super nervous at first at the possibility of losing it in the water. My insurance is long expired but I still use these pods that will run a float up to the surface. I figure I could at least recover my sd card if I lose it. Obviously if the water is really deep they won't reach the surface.

Perhaps it held position while the boat moved forward with handrail hitting it?
 
I always flew the Mavic Pro with the pool noodle floats. It affected the flying hardly at all. I have not tried the (much smaller) pool noodle floats on the Mini 3 Pro, and may not bother - I paid for the insurance.
