| Crashes are part of life with a drone but fortunately, most parts are replaceable. However, disassembly is time consuming, requiring the removal of up to over 60 screws of many different types. This guide should enable you replace almost all the parts that might break. | | | A means of organising the screws is absolutely essential. My favourite method is to take a sheet of A4 paper and stick the screws from each step to it with a separate blob of blu-tac. Write the step number against each. | | | Most of the screws require a 1.5mm hex screwdriver bit but with a variety of lengths and shapes and sizes of heads. There are four requiring a 2.5mm hex bit. These are the main screws retaining the arms and are all accessed from within the battery compartment. Some of these may have their heads filled with gum making it impossible to engage a screwdriver. Worse, it my not be easily apparent as they are not easy to see. The gum can be removed with a dental pick or similar tool but you do need to get it all out. You will probably need a screwdriver extension as they are otherwise awkward to access, or you may be able to use a 2.5mm Allen key. | | | Additionally, there are a few Phillips 000 head screws and also a few with an even smaller cross head. | | | There are several miniature multi-way push-on connectors. These flip off easily with a spudger under a corner but care is required in reconnecting them. Exact alignment is essential but not always easy to see. Applying no more than firm finger pressure, you should feel it click into place. Confirm that it's engaged along its entire length by pressing each end in turn. You might feel another click. Never try to force it or you risk ireparable damage. If it doesn't click into place it invariably means it's misaligned. | | The LEDs and sounders use very small connectors. It's important to disengage them by applying tweezers to the plug body, not by pulling the wires since they may pull out of the plug. Repair would prbablyprobably be very difficult. A pair of tweezers, a good light and possibly a magnifying glass or eye loupe are almost essential in order to reengage them, unless you havecan enlist the fingersservices of a tame fairy. | | | Solder connections are used from the motor control board to the motors for higher reliability than detachable connectors would be likely to give at the high currents that the motors take. You will need a soldering iron if removing or repacing any of the arms. |
