Introducing "the SUB-250 Gram Drone retriever"

DR300 Drone-Retriever

  

  • 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.
  • Procurement Options:
    • From Drone-Retriever.com @ $8.75
    • For those DIY folks:
      • Go to “Downloads” page for instructions on how to build your own unit.

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.
  • This is that product option.
