Now that Majestic has released an updated Q400 for P3D V4.1, those of you who own the Pro version of the aircraft can enjoy four times the smoothness in the controls using a 125hz mod. This is built into the pro 400 and is the same mod that was in the previous version. The mod basically overrides the default P3D program in favor of a Majestic one. The great thing is that I found a very helpful tool to quickly set this up as before you had to manually modify the Q400’s ini file and guess which weird access was assigned to your joystick and then hope that you didn’t need to reverse the axis. You can find this tool here. Q400 Control Config Tool
The tool only takes a few moments to install and configures the controls with a single save.
