Re: Using controller as data logger

Fully built into the latest version of Cleanflight.

This can use the inbuilt flash in a full Naze board, or you can use an Openlog board with external SD card.

There are also utilities to display the logged information.

Firstly, set I and D parameters to 0. Disconnect power from all bottom motors. Take all props off. Ensure that you are in acro mode (no self levelling). Connect a battery (not a power supply). Slowly throttle up so that the motors are just above idle, and verify that moving the aileron right/left ma...

On your Yaw channel, lower your P to say 2, and bump up your D by a lot, say 90. You might also try lowering your I to say 0.015. Tricopters, although their rate of yaw is fast, have a slow reaction to yaw inputs. You can help this by using a fast servo. My favourite at the moment is this one: m Als...
