Dronekit Intel Aero RTF

I am currently using an Intel Aero RTF with dronekit.

  1. I can use ‘vehicle.command’ using mavlink messages and ‘vehicle.parameters’ using PX4.

Is there any particular method recommended for control or mixing and matching is fine?

  1. When I set a value using parameters ( vehicle.parameters[‘MPC_THR_MIN’] = 0.5 ), the motors immediately begin to rotate at the specified value this includes for parameters like MPC_THR_HOVER.

This makes me think I am using the parameters wrong.
Is there examples of using the parameters to control the drone so that I can read up and get an idea?
