I'm close to the point where I am happy with my quad's tuning except for a slight amount of yaw drift. It probably wouldn't be a problem if I wasn't such a noob pilot, but I get all confused when it happens and I have trouble making my brain correct properly. I've trimmed my tx in both directions and it only results in pushing the yaw drift the other way. I can't seem to dial it in; it's almost as if the perfect step is 1/2 a trim setting. I've got a KK2.1 with 1.6 firmware and I have tried a bunch of combinations of PI Editor settings for yaw, but the closest I come to getting it to hover without yaw drift (or oscillations) is P=50, I=50.
Another possible cause is that I have a Turnigy 6X FHSS transmitter (cheap) and every time I do a receiver test, the values seem to change (meaning that they are 3 - 5 degrees off in either direction and have to be trimmed before flying). If I trim the rudder to 0 (in receiver test mode), push it all the way left or right and let it return to center position, the value on the kk will often be plus or minus 1 or 2 degrees. Is this common among cheap tx or is it common among all tx?
Any help is greatly appreciated.
