This project was born kinda due to my wife getting a new Trex 700N helicopter with a gas engine conversion. She chose a HeliCommand (Bavarian Demon) AXON FBL unit for it instead of using ArduPilot. She does not like how ArduPilot handles. We built her new helicopter and after I flew it I’ve been jealous as all get-out over the way her Rex 700 gasser with that AXON handles. It is the epitome of smooth yet accurate handling.
Gotta do something about this. My wife, learning to fly RC heli with ArduPilot, then trying out some of the commercial FBL units and deciding the FBL units are better, indicates there’s a problem.
Myself, @bnsgeyer and @Ferrosan put our heads together, threw ideas out on the table, and discussed how this has to work. We looked at the commercial FBL units that have accomplished this and pored over how did they do it? Thru true team effort, ideas, trying different things, we came up with VBar (Virtual Bar).
VBar is awesome for helicopter pilots that like a true manual flying mode that feels and handles like the real thing. Make no mistake, 3D pilots and race quad pilots will probably not like it. It’s not robotic enough. Scale pilots will love it. ArduPilot is definitely heavy into automation and robotics. But the scale pilots that fly for fun, or anybody that wants to learn how to fly a helicopter and have the controls respond like the big ones, are important too.
Here’s an intro video that explains it and how it works
I have built binaries for the most popular controllers for folks who would like to try out and fly VBar. These builds are Copter 3.6.7 with the VBar feature added. The firmware builds are here ->
