Derek Ernewein replied to Jae Paik's discussion Monster Quad in Desperate Need of Reasonable PID"I flew my 1000mm frame late last night. It leaned to the front right corner when trying to take off. Giving it more throttle quickly got it of the ground good though. I need larger landing gear to stop it from leaning.
Once it was off the ground it…"
Jae Paik replied to Jae Paik's discussion Monster Quad in Desperate Need of Reasonable PID"Yeah, I read that.
Seems like most tuning requires you to hold the quad in your hand. It gets pretty hairy with my monster. I will need to come up with some rig rather than holding it in my hand.
What's your quad's spec?"
"This is a good reference for Rate and Stab PID tuning on multicopters... http://aeroquad.com/showwiki.php?title=PID+Tuning
My quad is stable, but I'm about to put it through this process and see what I get. Then compare it to what I…"
Jae Paik replied to Jae Paik's discussion Monster Quad in Desperate Need of Reasonable PID"Yeah, at one point, I believe I hat the RateP to max but that wasn't helping much.
Someone is lending me their DX8 in few days so will try out the in-flight tuning feature.
Thanks!"
Jae Paik replied to Jae Paik's discussion Monster Quad in Desperate Need of Reasonable PID"Yeah, thought about slimming down the frame. Will need to scrounge up some money before going that step though.
Let me know how your behemoth takes shape and behaves. If you get it tuned well share the joy.
Thanks!!"
"Sounds like you should increase the RateP gain to make it not quite so sloppy, and adding some expo to your transmitter should help with the over corrections. Do you have a transmitter with rotary knob you can use to tune parameters while flying? My…"
Derek Ernewein replied to Jae Paik's discussion Monster Quad in Desperate Need of Reasonable PID"I am working on building a carbon fiber frame that will be 40 inches motor to motor. However, until all of the parts arrive (waiting on wire, connectors and screws) I have built the quad on a 450mm (17.5 inch motor to motor) frame that I got cheap…"

Jae Paik replied to Ruwan's discussion Share your drone info thread"Thanks Knut. I have put the ESC's about half way on the arm. Once more props arrive, I'll try that out.
If that doesn't, I work will try putting the APM2 on a more solid platform."
