Hello, I understand that for a piloting purpose the yaw servo is nice to have, but could a drone work just fine without it? If so, could the ArduCopter software work on a tricopter that hasn't got it, or some tweaking would be necessary? (I'm referring to both the radio controlled and autonomous flights.)

Because a Tri will have two props rotating in one direction, and two in another, it will have a natural tendancy to yaw, to different degrees based on the relative speed of these props.
It is essential to have a way (i.e., the yaw servo) to counteract that.
If you left off the yaw servo, the copter would not be able to maintain a heading (yaw orientation).
A multicopter with an even number of counter-rotating rotors uses rotor torque to control yaw (i.e., increasing speed of 2 rotors and decreasing speed of 2 other rotors on a quad). This wouldn't be possible on a tri because there aren't the same number of clockwise props as counterclockwise props.
So no, you couldn't do without the yaw servo on a tri.
