For many drone pilots, a frustrating but regular occurrence is having their costly drone caught in a tree. Unexpected wind gusts, flying mistakes, and equipment breakdowns can all cause a drone to quickly become lodged in branches far above ground. Improper retrieval techniques could be dangerous. This guide offers safe and efficient ways to rescue your drone from a tree.
Analyze the Circumstances
Before attempting to retrieve your drone, closely assess the situation:
- Visual line of sight: Try to identify where the drone is stuck in the tree. If not, use the FPV camera feed to locate the drone.
- Accessibility: Consider the drone’s height and whether the tree is safe to climb. Avoid trees that are fragile, rotting, or lack sturdy branches.
- Drone condition: Determine if the drone is just stuck or damaged. If it’s still on, check battery levels and, if possible, disable the motors to prevent further damage.
- Personal safety: Never risk personal injury to retrieve a drone. Be honest about your physical abilities and prioritize safety.
Basic Retrieval Techniques
Drones stuck on lower, accessible branches can be retrieved with simple tools:
Ladder or Step Stool
If the drone is caught on a lower branch, use a ladder or step stool to reach it by hand.
- Always place the ladder on solid ground and have someone hold it steady.
- Wear gloves to protect your hands.
Pole or Long Stick
Use a long pole, branch, or telescopic pole to reach higher drones.
- Avoid shaking the drone too much, as this could cause further damage.
- Create a hook using a coat hanger to help grip the drone or its propeller guards.
Fly the Drone Out
If the drone is still powered and in clear line of sight, you may be able to fly it out of the branches.
- Carefully throttle up and move slowly to avoid collisions with branches.
Fishing Line Technique
One of the most effective methods for retrieving a drone from a tall tree involves using fishing line:
Materials Needed:
- Fishing pole or strong, lightweight fishing line
- A heavy object (tennis ball, rock, etc.) to act as a weight
Instructions:
- Secure the fishing line to the weighted object.
- Approach the tree carefully.
- Cast the weighted end over the branch where the drone is stuck.
- Without touching the drone, pull the line to create vibrations that may free the drone.
Notes:
- Use 20 to 30-pound test line for sufficient strength.
- Braided lines are less likely to tangle than monofilament.
- Wear gloves to prevent cuts from the line.
Safety Issues in Tree Climbing
If climbing the tree is necessary, follow these safety guidelines:
- Never climb alone. Always have a spotter.
- Check the tree’s stability. Avoid climbing dead, rotting, or damaged trees.
- Use proper climbing equipment, including a harness, helmet, and ropes.
- Keep three points of contact at all times and test each branch before relying on it.
Expert Retrieval Services
If the drone is stuck in a dangerous or high location, consider hiring professional help:
Tree Maintenance Services
Tree trimming companies and arborists have the tools and expertise to safely climb trees and may offer drone retrieval services. The cost typically ranges from $75 to $150.
Boom Lift Rental
Renting a boom lift or cherry picker can provide access to drones stuck 30-50 feet high without climbing. Rentals can cost $250–500 per day and may require some training.
Professional Drone Retrieval Services
Some companies specialize in retrieving drones from difficult locations using specialized tools and experienced professionals. Though expensive, this option offers the least risk and the highest chance of success.
Things NOT to Do
Avoid these common mistakes that can make the situation worse:
- Throwing objects at the drone to dislodge it
- Using a high-pressure hose or water to try and knock it down
- Flying another drone to try and retrieve the stuck one
- Climbing beyond your physical abilities
- Using improper tools or unsafe climbing techniques
Preventing Future Drone Stuck Incidents
Once your drone is safely retrieved, take steps to prevent future incidents:
- Fly in open areas free from buildings, power lines, and trees.
- Limit the altitude to prevent exceeding your skill level.
- Use GPS modes that cause the drone to hover when signal is lost.
- Avoid flying in bad weather or high winds.
- Practice emergency maneuvers like return-to-home.
Conclusion
Although it’s frustrating when your drone gets stuck in a tree, it can be retrieved safely. By carefully assessing the situation and using safe retrieval techniques, you can recover your drone without putting yourself at risk. When in doubt, seek professional help and focus on improving your flying skills to prevent future mishaps.
