Hey.
Thanks for your reply. Yeah. I've checked all those things. LOL, multiple times. And tuning the PIDs doesn't fix it either, unfortunately.
The weird part is it will hover well and I can kinda flight it but when I increase the throttle it gradually roles to one side then when I decrease the throttle it roles back to level (and the harder I increase the throttle the faster and harder it roles), so I know the FC is oriented correctly and that everything is connected correctly.
I even upgraded my FC from a cc3d to a spracing f3 running betaflight. Still didn't help.
I talked with some guys on UAVFuture's discord chat and they said it sounded like the ECSs were out of sink with each other but unfortunately my ESCs aren't programmable. I tried connecting them to blheli configurator but they wouldn't connect. That's why I'm thinking it's the ESCs.
What are your thoughts?
Thanks again for the help.
