PIDs for a 250 helicopter.
« on: March 31, 2017, 10:31:22 pm »
Hi friends, I'm trying to tune my first CC3D Helicopter and it's hard to start (a 250 quad is easier).

Could you share the PIDs you are using in your 250 calss helicopter?

PIDs are down under "StabilizationSettingsBank1".  'bank2' and 'bank3' also.
Happy Landings!

I am not sure if this work for you, but for my QAV250 carbon fiber model it worked.
I inform you that the default (factory) PID values were NOT working on my drone, so i had to change them.
You can also use the TxPID and use your 2 knobs on your transmitter to calibrate the PIDs and be able to take off, for example knob 1 = EasyTunePitch, knob 2 = EasyTuneRoll. The Yaw is automatically calculated based on Pitch and Roll combination (i suppose). It worked for me and i am able to fly and take off easily now.

My values are (Stabilization tab => advanced => Bank 1):
  Roll => P = 0.00196, I = 0.00587, D = 0.000026
  Pitch => P = 0.00465, I = 0.01395, D = 0.000063
  Yaw (auto calculated) => P = 0.00496, I = 0.00941, D = 0.000042

Also, reduce your motors max power to 45 - 50%, this helped me, made my quad slow but strong enough to take off slowly, for better handling until i achieve a good balance.
Fly on a grass field in case you drop down the impact will make NO damage.

Hope i was helpful for you.
Happy fly.
