Default CC3D questions = HK250 helicopters flying with CC3D and Atom

I have two HK250GTs flying pretty well with Copter Control. One is controlled by CC3D and the other has an Atom doing duty. It is fun to learn to set them up and fly them. But it has cost me about $100 in destroyed hardware so far. I would like to learn more without so much expense.

The helicopter support in CC3D is not good. Can any of you help with a few of my questions?

If I increase Gyro Tau what happens? What is the limit?
If Vbar Gyro suppress get larger what happens? is there a limit?

How about Vbar Tau? What happens as it increases and what is a practical limit?

If I increase Vbar Sensivity what happens? And what is the limit.

When I increased Acroinsanity to 4 instead of .4 (typo) I had to replace some blades. What is a practical limit and what happens there?
What is Disable Sanity Check?

Rattitude Mode Transition default is 80 what if it is higher? limit?

AxisLock Kp? now what happens as this increases? to what limit?
What about MaxAxisLoc and MaxAxisLockRate?

Weak Leveling Kp? increase? limit?

Gyro Scale If I increase this number what happens?

Low pass filter : if it increases what happens ? Is there a limit?

PI --Kp, Ki and limit? what happens as this limit increases?

I assume Thrust PID Scaling can be useful to a heli. Has anyone tried it?

Any favorite flying modes? AxisLock? Acro+? Rattitude? VirtualBar? and WHY?

thanks,
Dave

Dave, Welcome to HeliFreak Multirotors Forums!

I've dabbled a little bit with the CC3D on a Trex 450 platform and it ended up costing me so much I just ditched the entire idea.

I hate to redirect you elsewhere, however you probably won't get a whole lot of help here using a CC3D on a heli.

When I had attempted this myself, I found most of the answers to my questions on the Open Pilot forums which is purely dedicated for the OpenPilot flight controllers.

Default thanks

Thanks. I know I was just hoping someone could answer a couple of those questions.

People at OP are helpful but we don't have enough heli support. Helis are the ba$tard children trying to learn without guidance. The OP code writers put their efforts into the GUI and then quit when they had multis working.

I want to learn all of this and go to the next level with the OP Revo board on a helicopter. It has GPS, return-to-home, waypoiints navagation, etc.

Anyone please chime in if you know an answer to a single one of my questions. Thanks, Dave
