A very simple “Passive Drone-Retriever Device” for your “sub-250” drone that only weight 7.4 grams.
The design shown is attached to a DJI Mini drone.
The unit can be attached to the top or bottom of ANY small drone with a takeoff weight less than 300 g.
Note:
Obstacle avoidance system, most likely, will need to be turned off.
Mounting to the bottom of the drone will facilitate hand launch and retrieval.
· The product includes:
The flotation device
Material: PE (polyethylene)
Reusable Zip Ties qty = 2
For attaching to your drone.
Configuration discussion:
Since DJI has basically captured the SUB 250 gram drone market.
We estimate that most pilots begin flying with the standard battery and then upgrade to the longer flight time PLUS battery.
We decided to produce the DR300 which will lift 300 grams such that it covers the additional weight of the PLUS battery.
For those of you who only fly the standard battery you can easily modify the DR300 [300g] into a DR250 [250g].
Procure a serrated bread knife and cut off 1.0 inch [25mm] of the foam material. You can also use a sharp utility knife, but for the cleanest cut the serrated edge works best.
This will also reduce your weight from 7.4 to 6.3 grams.

History
Over the past several years drone pilots have asked if we could produce a water rescue device for SUB-250 GRAM Drones.
This design does that in the simplest way while only adding 7.4 grams weight to the drone.
After directly providing DIY instructions, customers asked for a complete product.
The beacon unit is a Micro USB rechargeable device.
It is NOT a water activated device.
It is manually turned on and remains on until manually turned off.
It is activated by a single push button located on the top surface.
Long press the button to turn on/off.
Single press to change mode.
Operator can select various colors (White - Red - Green - Blue -Yellow - Purple - Sky Blue]. Image shows Yellow color.
31 modes: quickly flash - seven-color slow flash - seven color SOS mode - cycle slowly flash - remain on continuously - alternate between various colors - etc.
Longest battery life with slow flash
The beacon is attached with same mounting zip tie used to attach the foam float.
Additionally when not flying with the float the beacon can be attached to the drone with the zip tie to provide a recovery aid.
The Beacon adds 5 grams to the drone take off weight.
It operates for 4+ hours on a single charge however this will vary with mode selected.
Recharge time is less than 20 min.
Manufacturer claims 3 mile visibility which meets FAA night time collision avoidance lighting requirement.
