I just did a comparison with two servos, one from receiver and the other via CC3D at the same time. It looks good all of a sudden, little to no difference.. Idk, ether I am going crazy or I was using an old firmware before or something. I just got the thing so I am not sure what I was doing before my first flights, but I know that it was really annoying to fly, especially in the wind. I wouldn't have gone through all that trouble if I wasn't sure something was wrong. I will try the thing on the plane again tomorrow and see how it feels.
Thanks for your trouble and effort and everything! I'll report back tomorrow. Also, let me know if you need some help with development, I wouldn't mind.
I need a vacation...
