new cc3d owner. tuning q's

[rodg98133]

I have recently put a cc3d controller on my quad and loving it. I have set one of my flight modes up to rattitude, axis lock and cruise control and have successfully flipped and rolled my quad.

I have a bit of oscillation without even touching the controls. I know I need to adjust some settings but dont know where to start and whether they should be going up or down.

Any recommendations gratefully received.

Hi Mate, You need to start by lowering your gains as the standard gains are only to get you airborne. Also what shape is your quad, if its an X or H frame it';s a gift to tune as your gains will be the same for all axis but if its a discovery style frame it becomes slightly more complicated, start low gains on hover in rattitude and start pumping up your gains until it starts to oscillate then drop your gains about 15/20 % and it should be perfect ! Also do each of your gains one at a time so drop all gains very low ( about 50% lower than what they are standard ). Start with you P gain ( Proportional ) once the oscillate starts back it of about 15/20% as i mentioned before, Then do the same with your I gain ( Integral ) and last of all your D gain ( Derivative ). Your Derivative will be low and is best left at zero as it can mask a lot of problems when tuning your main P I gains so make sure the P and I gains are to your liking before adding D gain and also remember to lower you D gain first if you decide to retune in the future . Do all your tuning under the advanced menu as its much more precise ! Hope that helps.....Cheers....Aaron
