Hi , we want design flight controller with arduino through model based design for a quad rotor , what sort of quadcopter is suitable for this aim ? a provided one or assembling separate parts ?

I have Mission Planner and Arducopter V 3.2.1, but so far I could not open nor play any log, What I have to do to display the logs or play them?

I click in the download log and play log button in the Planner without any result

Thank you

I think Richard's solution is better :)

Just created a mod for apm planner 2.0 that allows you to trigger flight modes using keystrokes. I'm working on another mod that will allow me to use a midi foot pedal board to trigger flight modes and expression pedals for rate/gain tuning.

If anyone is interested and would like to take advantage of key commands for flight modes, just reply here and I'll forward you the details.

I have both set to 500 already. So I don't know what else to try.

In Stabilize mode you are directly controlling throttle output where as in throttle-assisted modes, you are making a request to ascend/descend at a given rate.  The parameter you are interested in is PILOT_VELZ_MAX.  Default for Iris is 250.  Just double that and set it to 500 and it will give it a mush more responsive feel.  PILOT_ACCEL_Z controls the acceleration and is also set at 250, but I feel like 250 is adequate.  See parameter descriptions here:

In stab mode if I go full throttle it takes off straight up very fast as you would expect. In alt hold or pos hold however it goes up but much much slower. Anybody know what I need to turn up to increase throttle authority? Thx
