- For smooth delivery, we must be able to pull the payload bay away from under the payload in the last moments of the ejection procedure. Therefore, the payload axis motor/servo must be able to accelerate downwards with at least 1g  (9.81 m/s2) acceleration at the outer edge of the payload bay. Also the max speed has to be such that we can pull the payload edge down by ~4 centimeters in around ~50ms. Probably it's more helpful to focus on this max speed figure than the acceleration. From a standing start, the actuator needs to be able to pull the payload edge down by 4cm in 50ms
- payload system must be able to withstand strong external torque, from a human operator who is forcefully trying to open or close the payload bay by hand
- the payload axis actuator (motor, position sensor etc) has to be waterproof or waterresistant
- the payload axis actuator must have enough torque to close the payload bay under the most extreme payload mass condition. Which is roughly 1.5kg of payload mass, 10cm off axis, meaning 15kgcm of **dynamic** torque on the axis
- the payload axis actuator must have enough torque to close the payload bay under the most extreme payload mass condition. Which is roughly 1.5kg of payload mass, 10cm off axis, meaning 15kgcm of **dynamic** torque on the axis
- Add performance counter implementation to autopilot and flightcontroller just like in px4
