Safety

  • If you are flying anywhere near other people, you are putting them at risk!

    • Be sure to maintain safe distances between people and your copter. Ensure that no one gets between you and your copter.
    • If you are flying too high or near airports you are putting manned aircraft and the people on them at risk!

Always consider that crashes can happen, because of pilot error or hardware or software malfunction.

  • Always ensure the battery cable is NOT connected to the power distribution board or harness until you are ready to fly.

    • Always Turn on the transmitter and ensure the throttle stick is all the way down BEFORE connecting the battery.
    • After landing the first thing you should do is disconnect your battery cable.
    • Do not attempt to fly longer than your batteries safe capacity. If you have insufficient power, the automatic controls can require more throttle than the available and destabilization may occur.

At full power, an average sized multi-copter can exceed 32 km/h, can ascend to hundreds of meters and easily travel more than a mile in distance before running out of battery.

  • Always remove your Propellers while you are testing motors, your hands, arms and face and those of your friends will thank you.
    • When the battery is connected, always assume the motors are armed; You can check with a short throttle pulse.
    • Don’t pick up the model and the radio at the same time, you may bump the throttle.

Always remove the propellers whenever you are indoor!

  • After landing the first thing you should do is to hold the throttle down and to the left for several seconds to “Disarm” the motors. Disarm condition can be tested by moving the throttle stick up, if the motors do not move it is disarmed.

Even when disarmed, the throttle stick should always be kept in the full down position except when flying.

  • When testing or flying any of the (waypoint) navigation modes (using GPS):
    • Ensure that your GPS has “Lock” before arming and takeoff.
    • Check that your home position on your Ground Station is in fact correct.
    • If the GPS does not accurately report your home position, reboot and wait for 8 or more satellites (not just 3D lock) and check again.

Do not start using any other modes than Stabilize or Stabilize plus Simple until you are VERY comfortable flying your copter.

  • Important primary response to a crash, inadequate landing or unknown flight controller state.

    • The first thing to do is throw a towel over your copters propellers (Propellers may start spinning unexpectedly
    • Then immediately disconnect the battery.
    • A large towel is your most important piece of safety equipment followed by a fire extinguisher and a first aid kit.

Always follow the law: Our personal use of MultiCopters (models in general) is continually under attack by those who fear ‘drones’ and invasion of privacy. If you break the law, or invade someone’s privacy, or put them in harm’s way, you threaten the future of our personal use of models. Please, understand the law and the rights of others – and fly accordingly.

  • Move the control sticks in small measured increments and don’t yank on them. If the copter is properly calibrated and balanced it should require only small stick inputs to control altitude, direction and speed. Be especially careful of large throttle inputs, as a copter can gain (or lose) altitude very rapidly.

  • In manual flight modes, the most critical part of a successful flight is to maintain a clear vision of the Copters Orientation (direction it is facing).

Specially while learning it is very important to keep your copter appropriately close to you to aid in maintaining visual orientation. Generally: more than 3m but not further than 10m from you.

  • High or unexpected winds or gusts can make flight considerably more difficult.

    • High winds can prevent forward progress or spin the copter around causing you to become disoriented.
    • The higher you are, the more likely high winds will be a problem.
    • Avoid flying at high speed or high altitude until you have gained considerable confidence in both manual and automatic modes.

Radio signal loss can also occur. If your copter is approaching a potentially interfering object, immediately switch to stabilize mode and land or retrieve the copter to your location.

  • RTL can provide a safe Return to Launch if it starts to get away from you.

  • Set up a FailSafe on Radio Fail with an RTL or Descend response to save your Copter and prevent Injury.

  • GeoFence establishes an automatic flying perimeter that will force your copter to stay in a safe proximity.

  • Do not rely solely on the above safety modes, always be ready to take back control in stabilize and set the copter down.

  • Especially do not rely on the above safety modes to perform maneuvers or training that you would otherwise consider dangerous.

  • These modes are a supplement to, not a replacement for sound safety practices.
