Variable Pitch FBL stablized Tricopter

I was starting to think that a FBL controller would be better for a variable pitch quad than dealing with all the Hz that a multirotor controller wants to spit out. But I just could not figure out how to deal with yaw so I started to give up on that idea. Then I found this:

And it was like DUH! I like tricopters more than anything, why didn't I think of that? And it leaves a servo channel to deal with the yaw stuff. Basically it is setup just like a 120 degree CCPM helicopter with each rotor disk pretending to be just one corner of the swashplate. Since FBL setups are for servos then there is no Hz issue, and with a Skookum 720 or the new Align APS you can have self level or RTH, and FBL units can handle the vibs of an engine because they are proven to work on gassers......

See how it flies:

Just found this down a bit from the original post:

"This unit isn’t setup like most designs. The elevator is only the rear channel instead of 120ccpm adjusting the front at the same time. Each rotor has a dedicated function which doesn’t rely on another reaction to achieve it’s direction. 120ccpm theory will generally end up with a unit that is always to sensitive to actually fly once you accomplish a hover. 3D with this would be more like an airplane then a heli."

Don't really understand this, but obviously it can be done and works.......

Very clever and very cool.  The guy sure does nice work too.  Looks like just the project for you.  I'm not sure Home Depot is going to have everything you need this time.
