I supposed most FBL unit has the function. But what it actually does? Can enlighten? hahaha

its very important for FBL controller to have piro comp for aerobatic flight.

its not so essential for scale usage.

in a nutshell here is what it does.

when fly a flybar heli. u give right aileron input the heli will bank right. now u start to give rudder input the heli will keep flying to the right and piro.

for the early 2 axis FBL controllers without tail gyro, this cannot be done as the FBL controller has no idea which direction the heli is pointing! so when u do the same move, the heli will haywire.

nowadays all FBL controller are 3 axis,thus can sense its heading. what it does is that it compensates for piro movement of the heli and keep the swash fixed to a certain orientation when the heli is piro-ing and moving at the same time. it thus mimics a normal flyabar heli.

cheers!
