Uncontrollable takeoffs can be caused by a few issues in the system:

Potential source Causes What to Inspect for
Poor Positioning Performance Taking off in Position mode requires good performance of the positioning system. Dust, grime, smudges can populate on the tracking camera during the lifecycle of the aircraft, this can cause the positioning system to lose clarity of its environment Visually inspect the lens for smudges or damage. Use a microfiber cloth (similar to a pair of glasses), or an alcohol wipe to clean the lens.
Motor Damage Damage to the propellers, damage to the carbon fiber frame, loss of screws in the motors or motor protectors can cause abnormal vibrations in the system which can be an issue for the positioning system. Inspect for damage on the carbon fiber frame of the aircraft, and the outer motor ducts. Damage to the outer motor ducts can be repaired in the field using the provided drivers. Damage to the main carbon frame must be fixed in our facility, however temporary fixes like electrical tape or glue can be used in a pinch but are not recommended. Inspect the screws, ensure there are no missing screws in the outer ducts or the motor mounts, and ensure all screws are properly tightened. Inspect the propellers, ensure the integrity of the propellers as small chips and scratches can be enough to cause vibration in the system. If damage is found replace these propellers as soon as possible.
Poor Lighting Damage to the LEDs can cause the positioning system to fail in dark environments due to a lack of light. Damage to the front LEDs will need to be fixed in our facility.
