So, my Quad has a KK2.1.5 board, Hobbyking Blueseries 20A ESC's and 1000kv Motors.
With stock firmware on the KK and the ESC's it flew, but was very twitchy, even after tuning the PI settings.
So I decided to flash the Steveis KK2.1.5 Firmware (v1.17S1 Lite). After that, it flew a little more stable, I could raise the P a little more without it oscillating, but it was still twitching a little and overcorrecting when changing angle.
So again, I flashed the ESC's with the SimonK firmware. Now, it's not overcorrecting, feels very locked in and extremely stable. But now, when I'm flying forwards, when it gains a little speed, it starts throttling up and climbing, without me changing the Throttle.
Here a little graphic, on how it's altitude changes, when pitching forward.
When it throttles up while flying forward, the motors don't spin up smoothly, but kind of "hopping".
What could cause this problem? Because when I hover it doesn't do that.
I also have minor problems balancing the motors, because 2 of the screw-on Propshafts (NTM Prop Drive 28 Series Accessory) aren't perfectly straight when screwed to the motor, so they are causing minor vibrations. But I don't think that's the problem, because when I Yaw, the motors also speed up and create different vibrations, but don't cause the throttling up. The Props should be perfectly balanced. Any Tips?
