Ranger Pro Unboxing and Assembly

  • Open the WISPR Ranger Pro Carrying Case to reveal the drone

  • Attach the landing gear by inserting the two metal pins on the leg into the two holes present in the landing gear, and then screwing the red connector ring on tightly to connect the two parts. The antenna mounts (velcro pads) should be facing toward the outside of the leg

  • Attach both of the antennas running from the body of the drone to the antenna mounts on the outside of the landing gear

  • Remove the drone from the carrying case

  • Unclip the arm holders and remove the straps securing the propellers

  • Unfold arms and lock them into place using the latches attached to the drone arms

When attaching the landing gear, which way should the bracket for the antennas face?

  • The antenna bracket on the landing gear should always face outwards when attaching the landing gear.

My leg bracket connectors are becoming loose frequently. What should I do?

  • Please follow these steps to ensure the proper functioning of the leg bracket connector:

    • Verify that the O-Ring (included) is correctly placed inside the leg connector, identified by the red metallic ring. Take care to examine the O-Ring for any signs of stretching, wear, or breakage. The O-Ring plays a critical role in maintaining a secure connection and preventing vibration.

    • Thoroughly inspect the threads on the leg connector for any worn areas or breaks that may impede the ability to tightly screw on or maintain tightness during flight.

    • If you find that the O-Ring needs replacement or if the leg connector is damaged in any way, we kindly request you to file a ticket through the provided form. Our team will be ready to assist you promptly.https://wisprsystems.atlassian.net/servicedesk/customer/portal/3/group/11/create/38

How should my propellers be attached to the drone?

  • The drone uses 2 pairs of counterclockwise (CCW) and clockwise (CW) propellers. The CW propeller has a ‘L' marked on it, and the CCW propeller has a 'R’ marked on it. You can easily tell the difference in the CW and CCW propellers by these markings. The picture below shows how the propellers should be positioned. If for any reason they are not positioned in this manner the drone will attempt to launch and ultimately crash, potentially causing damage to the propellers, motors, GPS, or the body of the drone.

When should I check the condition of my propellers?

  • It is imperative to conduct a thorough examination of propellers prior to each flight. It is recommended to inspect the propellers for indications of cracks, fractures, or any signs of detachment from the motor. In the event that any of these abnormalities are detected, NEVER launch the drone. Even a small nick could cause unwanted flying conditions.

    • If a propeller is damaged, prompt replacement of the propellers is vital to ensure optimal operational conditions.

  • WISPR offers propellers in pairs (CCW and CW) or sets (2 CCW and 2 CW). A single propeller is not available for purchase.

When replacing a propeller the entire propeller (either CCW or CW) must be replaced, not just one blade!
