Good afternoon, thank you very much for your videos. Your channel is very interesting. I am from Ukraine. 🇺🇦🤝🇬🇧

Hello, I am currently working on the same exact model design, could you tell me why u used 2 servos and not 4?

[@wowthatflies]

Because two are enough :) This thing has two motors, one clockwise, one counterclockwise, so it can control thrust and yaw just by motors. Two things remain, pitch and roll, so you can control them just by two servos. This particular machine has diagonal flaps, not a pitch flap an a roll flap as in the standard designs, but nice control is still possible. For this machine, it seems as if four servos would just increase the weight without much of added benefits. Ardupilot's code for Coax does not provide redundant yaw control even if four flaps are enabled, and, frankly speaking, yaw authority of flaps is just worse at this scale.

@@wowthatflies My design has a 4 servo x fin configuration and when I have the design ready I think I will really benefit from all your videos. I guess my biggest concern is how to balance the torque generated by single motor.

Anway,I dont think people actully realize how much time or effort it take to even get near a hovering stage you have done some really great work on co axial copters. We would all benefit if you could explain how you come up with your experiments and how you make decisions. Thanks!

You may benefit from watching the SC1 video, this is a single copter similar to what you are apparently building.
