Hi guys,
I read that one can attempt to quadrocopter Autotune pids.
Is it possible (or who have already tried) Autotune pids to make a helicopter?

This will be something to look into, but I have not tried it yet.
I'm not sure if it will work because of the way the helicopter rate controller works. We have an extra FeedForward parameter in there that the quads don't, and I expect it will not work with the auto-tune function. There's also the difference in the aerodynamics. The autotune function is amazingly sensitive, and I have a quad that will not tune due to frame flex. I suspect we may have the same problem with helicopters. Not that the helis flex, but they behave slightly differently than a quad.
I plan to try this out, but I haven't yet.
You know I wonder about this as well!
I have played around with other autopilots for helicopters. One of the ways to tune in the autopilot is to do a log flight of about 5 minutes. Basically you hover the helicopter while giving small wiggling inputs to the cyclic. Once that flight is done you would check the logs match match up certain perimeters and your done no more tuning!
