Yaw control in tri copter without tail servo

1

Hi guys, hope all doing good.

I just want to ask how does a tri copter drone will yaw if it does not has tail servo. Like scarpean UAS tricopter drone it does not has any tail servo. Also my drone configuration is tilt rotor with 3 motor config where 2 front motors has servo attached for transition and tail motor fixed. In that case, how does it yaw?

Thanks in advance.

The front motors move in counter directions in MC mode to effect the yaw.

Good luck.

Ok,but a small question arises that if that yaw is efficient, why not all tricopter can go without tail servo? Why need for that thrust vectoring using such servo?

Thanks in advance

Yaa thanks, but out of box, what if my front 2 motors are fixed and my cruise motor is my tail motor which can tilt front to do transition.

In simple, my vtol mode, my front 2 motor(fixed) and tail motor (tilt up and down for transition). And in fixed wing mode, my front 2 motor will stop and tail motor will tilt up for cruise.

In above case, will the system will yaw in vtol mode? How efficient that yaw will be??

Thanks in advance…

@gengatharan you would not have yaw stability. You must have one tilt control.

Since your front motors can tilt they are positioned at the right angle by your autopliot to balance the torques of the rear motor.
