"I'm tired of waiting for pixhawk to be in stock again in european stores. What is the best alternative to pixhawk and APM as plane flight controllers? I've been told about PitLab, can someone tell more? Thanks"

"You saved me from posting exactly the same. When connecting by 3dr radio it works well in the background, but that alert prevents from having further telemetry. I think this started happening after last MP update, but I'm not sure."

"@dr0n3droid My problems started here: http://tinyurl.com/pj3yp3gNow I think that I should have kept those clones and just transplant the voltage regulator from the old (original) PM to the new clone. Now I have none. I've sent the clones…"

António Cabral commented on Chris Anderson's group ArduCopter User Group
"@dr0n3droid Thank you for the speedy response.Would you be kind to show me/us a link to one of those kind of regulators? Just as as an example. Perhaps it might be simpler to get one than I though. Thank you again in advance."

António Cabral commented on Chris Anderson's group ArduCopter User Group
"Can a Attopilot fully substitute a power module in giving power to an APM 2.5 and sending voltage and current readings to be sent by the telemetry? If not, what part is missing to make it complete? THanks"

PID: What's it for and how does it work?

Posted on March 27, 2013 at 9:00am 5 Comments

As my first blog post in diydrones I'd like to show, specially to other noobies what is the so much talked PID so much used in our Arducopters and Arduplanes.

This video has substitles also in english and russian but you have to select it to activate them.

It shows in a very dummy but effective way what PID is, and hope it makes things more clear for…
