Product Description

Multi-purpose Life Preserver Attachment

Deploy and Float

 

The multi-purpose life preserver attachment is the culmination of several functionalities that will aid responders for water SAR missions:

 

Deployable 

Drop the life preserver to someone in distress. Cut response time when it matters most. The system uses the E-flite Servoless Payload Releases to drop the preserver using the P3 controller. By simply swapping out the wiring harness on the inside of the P3 with the RCDH wiring harness, this system can be operated without adding additional channels to the P3 controller! The deployment is triggered by switching the flight mode switch from P to F twice. Without the need to add switches or mechanical modifications to the controller, this is a truly elegant solution, for which I cannot take the credit. This "hack", designed by RC Depot Hobbies, is utilized for deploying the life preserver. 

 

Float-able

Keep the preserver attached to the drone, and land on the water! The diameter of the preserver is perfect for a stable water landing, and doesn't create a significant amount of water tension when taking off. 

 

Land-able

The preserver attachment also serves as an extended landing gear. Have no fear landing after you've deployed. 

 

Re-loadable

The system is self-contained. Nothing is attached to the life preserver (that will inevitably be lost). This means you can have a stack of life preservers straight off the shelf - simply load another preserver when ready. 

 

Camera Function Remains

The position of the life preserver allows for the camera to be used forward facing or nadir facing (straight down). Take off and fly using the camera facing forward, and position yourself above the target with the camera facing down. 

 

Manual Release

The E-flite Servoless Payload Release features a manual release mechanism, meaning that even if the drone is off or has somehow failed to release the preserver, the preserver can still be released. 

 

Additional Parts

The full system requires some parts in addition to the designed part shown here.

 

The Math

Assumptions:

Life preserver = 200g

E-flite Servoless Payload Release = 18g x 2 = 36g

Multi-purpose Life Preserver Attachment = .93 g/cm^3 x 33cm^3 x 2 = 61g

 

Total system mass = 200 + 36 + 61 = 297g

 

Installation Instructions:

  1. Swap out the wiring harness inside the P4 with the RCDH Landing Gear Retract Wiring Harness per this video: https://www.youtube.com/watch?v=QNgcIICaQaI 
    Ignore the part about the actual landing gear mechanism, we just need the wiring harness. 
    *If selected, I will make a video that shows this. 
  2. Run the servo wire extenders out of the Phantom 3 body and down the leg to the bottom of landing gear. Secure with zip ties along the way. 
  3. Install the two multi-purpose life preserver attachments to each side of the quad. Snap 'em on!
  4. Zip tie the attachments to the bottom of the landing gear using the slots. 
  5. Install the two servoless release bases using four #8-32 X .375" screws and nuts. 
  6. Attach the releases onto the bases. 
  7. Tie paracord between releases and the end of the legs. Tie the cord on the outer holes of the releases first and then wrap around the bottom of the preserver, tying a cleat hitch on the end of the leg (http://www.netknots.com/rope_knots/cleat-hitch). This allows the cord to be redone and tightened over time. 

 

Procedural Instructions: 

  1. Load a life preserver by wrapping the release plate (hanging by two cords) around the bottom of the preserver and attaching it to the payload release base. 
  2. Take off (after doing pre-flight checks and readying the aircraft) and fly to the target location.
  3. Use the camera to position the quad above the target.
  4. Flick the flight mode switch from P to F twice, releasing the life preserver. 
  5. Or keep the preserver attached to the quad and land on the water as necessary. 

 

**Upon selection, the system will be built and tested to the max.

**System was designed for a Phantom 3 (P3), to utilize the wiring harness from the RCDH Landing Gear Retracts.

**Adding any payload to the P3 will decrease flight time and performance.
