"Mark, there's a big tuning guide in the manual here."
Mark replied to Mark's discussion APM 2.5 information"Any more input for me Chris on what gains I should reduce beyond the roll and pitch.
Also I dont have a 100% understanding of P I D so any rate suggestions are welcomed with open mind.
Lastly as mentioned above the copter is sweet in Stabilze…"
Mark replied to Mark's discussion APM 2.5 information"Everyone of the gains ? I have already made the roll and pitch less and that smoothed the copter in Stablize.
What gains am I to reduce to help the GPS modes ?"
3D RoboticsChris Anderson replied to Mark's discussion APM 2.5 information
"4s is 25% higher voltage, so the motors are that much more powerful. You need to dial down the gains by that much. "
3D RoboticsChris Anderson replied to Mark's discussion APM 2.5 information
"Ah, I think it's the 4s battery. The gains are tuned for 3s. Can you try that?"
Mark replied to Mark's discussion APM 2.5 information"Bone stock dji 450 10"props 4s battery
Again flies super smooth in Stabilize just want a more locked gps mode.
the copter seems a bit lost in Hold modes"

"It really depends on your frame. The default PIDs are set for the standard 3DR quads and hexas. If your frame is smaller or you're using more powerful motors, you'll need to tweak gains. Can you describe your frame, motors, and props, so…"
Mark replied to Mark's discussion APM 2.5 information"Chris with 2.9 loaded what parameters can I tweak to have it hold position better.
It dips and wanders alot, to the point of me having to take it out of hold to regain control"
Mark replied to Mark's discussion APM 2.5 information"On the 11th try it completed the upgrade going out back now"
Mark replied to Mark's discussion APM 2.5 information"Ok so the upgrade does not seem to want to upload. After each of the six attempts the screen says
Upload failed ?"
3D RoboticsChris Anderson replied to Mark's discussion APM 2.5 information
"Your APM is connected via USB and you've selected the right com port, etc? You should just click on the icon of the quad (it should say 2.9) and the upgrade should begin. "
Mark replied to Mark's discussion APM 2.5 information"How is the upgrade done, I go into misson planner and click on firmware and nothing happens ?
What is the procedure ?"
Mark replied to Mark's discussion APM 2.5 information"You mean the auto level calibration ?
Im off to go do the download now"
