Hi.
I am planning to build a DIY octocopter heavy lifter, in order to lift a canon 5d. I thought to do a X quad configuration, dual motor on each arm, the same style as the Y6 but, as it where a X8, thus reducing the hardware and weight. The firmware would be the same as the quadcopter, with 4 outputs from AC2 to "Y" cables, each two outputs to the two engines on each arm.
Would it work this idea?

That was my doubt, if each 2 motors should rotate in the same direction, thus the yaw movement works correctly. I think must be in that manner. But does it affect stability? Do you lose the stability that supposedly can give two coaxial motors running?
Im also in the process of building a octo. Mk frame, ardupilot, to carry a nikon slr.
I had the same idea a while back regarding co-axial motors. Technically it should work.
One APM, 8 motors, 8 ESCs and splitter cables for the signals.
I would however test this if you can. If you have an arducopter, just borrow or buy 4 motors and escs and test it.
Im keep to see if it works. It would be nice if it did, cause then you wouldnt have to mod the code.
One other point is that it wouldnt technically be co-axial, because both props on each arm need to turn in the same direction. If they counter rotated, you wouldnt be able to contol the yaw. If you wanted counter rotating, u would have to mod the code....
