So I've taken 4 flights over water so far with my spark.  Two were flying from an anchored houseboat and I was up on the roof.  So no worries other than the fact that when I did return to home it kept wanting to go to an elevation LOWER than where I was standing so I didn't chance it and cancelled return to home and manually had it hover in front of me and did the catch and flip sideways to kill the rotors.  

This is an autoedit that I got from Skypixel:

Nice area and also good place to hang out I can imagine

This week I took 2 flights from my wakeboard boat.  My friend is a really good pilot and he has a P4 and a mavic that he's really good with and has started to build racing drones, so I trusted him.  

On the first run, My wife was surfing  and the drone started to return to home (way away from where she started surfing).  We're thinking there was a setting that basically computed battery life and when it realized it was father away than it had juice to return to "home" that it aborted. So we were able to reestablish control and brought the boat over to the drone and my buddy brought it into me and I caught it off the back of the boat's sundeck.  

So much for trusting somebody with flying your 'toy' ;)

That looks a bit better, but how does it fly?

This may be a dumb question but why are people afraid to fly it over water? Is it a known issue that it can just fall out of the sky over water? Do you lose connection more easily with the Wi-Fi? Why would water interfere more than land?

Nope, but can't retrieve the Spark if we crash into the water without a snorkel. DJI Care Refresh only works if we find the body.

This is my propousal for a lifejacket

The idea is have a very low impact in the weight and propellers, and at the same time warantee recover the spark for the insurance.







The weight of spark is 344 grams, with the lifejacket 377, it is rigid and has a volumen 4 times more than requrieded to avoid the dron sink. Of course is only a lifejaket it is no valid to take off from the water.

Iʻm a Spark owner, but I also have a 3D printer I use to make stuff. Iʻve made components for the TBS Discovery, DJI Flamewheel drones, so naturally, I was intrigued when I found this. Iʻm planning on printing these out eventually. Of course, the conundrum becomes apparent. Attaching this to the drone supposedly voids a warranty, but can simultaneously save your Spark from sinking into the deep.

Scared the crap out of me to fly over this sand bar when I was kayaking on Saturday. I was out of my boat also.

This was on Youtube.  



I am working on copying something for a Spark.  The part I can't find in China is the long plastic bolts to push thru the foam balls (easy to find at craft store).  Then you get a set of the legs for a Spark, connect the bolts as shown, and you have a very stable landing platform (more so than the Mavic because the Spark will have a lower CG).

Note, if you decide to do  DIY project like this, test it in the tub before you take it out in the kayak.  There are other videos people have shown of their Sparks flying and landing on less than flat sea, so it can be done.

I think there are good approaches here. Personally, I'm preferential to the spherical floats because the shape would be less drag in air, and on water it would breach surface tension on take off easier as well as adapt to level.

I'm going to follow this one!  Nice to see al these ideas.
Did flew the spark down off a waterfall, it was quite nerve breaking. No way to retrieve the drone when something goes wrong.
Same thing when flying over the sea... When something goes wrong, you precious drone is gone. When it floats you got a change to find it.
The footage of the waterfall can be found here (fast forward to 20seconds)

After being terrified of flying my P3P over the water, the spark doesn't terrify me at all. My the lower cost of it makes me more relaxed. This is one of my pic from flying off the boat in the Bahamas.

You should put wax at the bottom that way water won't soak thru.

I have seen somewhere home made anti-sink legs - generaly u can find on aliexpress or amazon 3 types of legs (sadly short) but #1 & #2 & #3. On one video i have seen styrofoam balls attached to legs like those [link] in few dollars cost and few balance test u can do it easly - especially when u want shoots 10-30 cm above water when spark just falls down if its to close to water surface

Would love to see DJI officially build something like this into the landing gear system on future models - even drones that take off from water. Interesting times ahead - roll on the P5 and M2...

Thanks for sharing. Even your spark has those "protection" , you still need to be careful and protect your spark from water.

I really need a viable solution. I'm not trying to land on water but I want SHTF protection so I can at least recover it. Where I plan on flying it's over 100' deep so if it goes down there would be no getting it back. It's also not in DJIs interest to create this product or make the drones float which kind of sucks.

I'm thinking of making my own using some styrofoam balls and some raised landing gear already purchased from the auction site.
Alternatively, these should fit the bill quite nicely:

Well Russians  have developed a prototype floating apparatus for planes .  When a multi million dollar  plane do not have this feature , a 700 $ drone is too far away for such a concept !

I would like to see the Mavic or the SPARK landing with some more gravitational force from the sky rather than a soft landing !
Probably a CSC in the air by the sticks would help

Cool video , but can you please advice what the wait after this experiment on the SPARK.

Also can you do a free fall at least from above 10 meters to see the REAL effect on water .

You could always clip one of these on it.  :-)

Your spark is under water by the time those bouyancy floats activate, useless.  You want something like this. They will be explaining it in an upcoming episode.
  At 9:12.  Similar to the ones above.

I would guess that a drop from 10 metres to any surface, let alone water, is not a good idea. You can however take off from and RTH to water.

I've flown my spark about 1.4km away out over Lake Ontario from my position on the shore.  I was definitely nervous at first, but got comfy pretty quick.

i saw on amazon some bouy's that installed on the bottoms of the motors.  they were basically white foam balls that slid on the bottom of the motor housings.  This would likely give enough buoyancy if it hit the water not to sink completely.

Freefall won't work, you would have to weight the floats and that would exceed the Sparks lift weight, if the motor fails, it will simply roll over in the air and fall 10 meters onto it's back in the water.

There are leg extensions now that are long enough to poke into the balls, you make a hole in the ball first, then fill it with hot glue, then stick the leg extension into it.  Works like a charm
