+ | * To not exceed the 8A / ESC connector output the battery voltage, motor and propeller should be selected so this does not happen. The ESC can be rated higher as it does not noticeably effect current draw, only efficiency. | ||
+ | * Preferably select a frame so decks can be attached. It is hard to make e.g. the flow v2 deck and lighthouse deck work at the same time as the battery needs to be placed somewhere, which is normally in the center, above or below the Bolt control board. | ||
+ | * 4in1 ESCs can be convenient but for the Bolt it is often better to use 4 separate ESC mounted on the arms as this frees up space for decks. | ||
+ | * If higher then 8A is wanted only connect the signal wires from the ESC connectors to the ESC. Preferably still power the Bolt control board via the battery connector so the battery voltage can be monitored. | ||

+ | ===== Configuration ===== | ||
+ | The Crazyflie firmware will automatically detect that it is running on a Bolt and activate the right modules. However some of the configurations still has to be done during compile time and making them run time configurable is currently work in progress. | ||

+ | * The ESC PWM output is set by default to 400Hz. Use ESCs which can handle this or compile with [[https:// | ||
+ | * It is wise to do a range test before flying far away. | ||
+ | * **Be safe**, it is experimental software. Run all testing **without** props! |
