Hello, has anybody been succesful in obtaining a decent altitude hold?In Ardupirates it was working farly good, but I can't seem to find the right PIDs.It doesn't correct quick enough.Even with a lowered P it goes up and down till it eventually stops(crashes) on the ground or goes up in the sky....Just looking for some feedback on your PIDs.Cheers,Emile

Wasn't aware of that ( I only have 6 channels :( ) Anyway I had my first success in ALT HOLD, so basically I'm replying to myself... :) I have lowered P value from 0.3 to 0.1 and I from 0.1 to 0.05 and is working much better!
I have seen now that today there was a little change in attitude.pde tomorow I will give it a try,
Anyway latest changes in code have resolved my YAW issue, now it looks rock solid.
I've got to say that the latest zip has done wonders for both stability and altitude hold on my non-standard frame. Yes, pirates altitude hold was better, but this is almost there. On previous revisions, my alt. hold behaved like you describe. However, the deviation on latest code and defaults is less than a foot (when it's using sonar) in my case.
Usually all default pids are just fine but have you teached throttle hold value to your quad?? You should quickly flip channel 7 when your quad is holing level.
