  • Page 6 Parachute Manual for DJI M600 and M600 pro 2.3 Motor cut-off PCB Picture 3: PCB to stop the motors from spinning The motor cut-off PCB (Printed Circuit Board) is responsible for stopping the motors from spinning in the moment the parachute gets deployed. This safety feature reduces the risk of the parachute lines getting tangled in the propellers.

  • Page 9 Parachute Manual for DJI M600 and M600 pro Run the hook all the way through the loops of each cord as shown in step 6. When done the loops should get tightened to get a solid and strong knot. Pull the hook close to the lid. At the end the push the cords into the storage container run- ning through the slots at the side.

    Parachute Manual for DJI M600 and M600 pro 3.2 Installing the mounting plate The installation of the mounting plate is quite straight-forward. First you need to find a position right above one of the batteries that fits best for your setup. If your are using the M600 pro version one of the position will not be available through the bigger top cover in the front.

This way you can easily access the bottom area. Unplug the XT30 socket which is powering the servo for the landing gear.

As an example the port F3 from the A3 flight-controller can be used.

  • Page 17 Parachute Manual for DJI M600 and M600 pro Remove the rubber bands from the parachute and use your fingers to pretend and acciden- tally opening of the plastic cover. You can only remove the one at the bottom which is closer to the spiky end and remove the other one when the parachute is half inside of the tube.
  • Page 18 Parachute Manual for DJI M600 and M600 pro Put on the lid to protect the parachute from sun light and other environmental influences. The parachute cord should lead out underneath the lid at its designated position pointing to the center of the M600. Place the container on the mounting plate with the small pike (arrow) at the bottom pointing towards the open padlock symbol.
  • Page 19 (like a bottle filled with water) inside. 4.2 Visual status signal The DRS-M600 system is equipped with a three-color RGB (Red, Green, Blue) LED (Light emitting diode) to inform the pilot about the internal system status as described in table 1.
  • Page 20 Parachute Manual for DJI M600 and M600 pro 4.4 Storage If you don’t use the parachute rescue system for a longer period of time we rec- ommend to take out the parachute canopy and remove the tension from the deployment unit. Always store the system in a dry environment to prevent moisture accumulating inside of the parachute canopy which might increase the time for fully inflation in case of an deployment.

  • Page 22 Table 2: Available parameters to customize configuration 5.3 Time The DRS-M600 is capable of naming the log-files based on the current date and timestamp. Therefor the systems time has to be set in advance. This is done once after fabrication but might be repeated if the system was not supplied with power for a very long time or you want to change it to your time-zone.

  • Page 23: Before Flight

    After each flight it is recommended to do a short visual overall inspection to see if any part or component looks abnormal, worn out or broken. Replace damaged parts before using the DRS-M600 parachute rescue system the next time. 22/27...

The wires have to be in the middle. Use a strip with a width of 140 mm which acts as a helping tool to fold the parachute to the cor- rect size.
  • Page 26 Parachute Manual for DJI M600 and M600 pro Flip the fabric over multiple times starting at the end where no wires are. At the end you can role the last part of the fabric to get nice tube. Roll up the wires of the parachute using your pointing and little finger.
