To turn this into a better camera platform the KK board has to be replaced. The reason being, it only has a few basic flight modes including self level, but does not include altitude or position hold.
The flight controller should include the flight modes mentioned and support advanced modes like return to home, waypoints, and follow me.
I've been looking at either the DJI Naza, or the open source PX4 controllers like the 3DR Pixhawk. I ultimately decided to go with the HobbyKing HKPilot32 which includes GPS and Telemetry. This gives me a lot of options at a good price.
I ran a more flexible wire to the internal measurement unit for the gimbal controller. I still think the wire is too stiff but its much better. Before the change, the gimbal was freaking out on pitch but its behaving better and I'm left with some tuning to do on roll.
Good news is I don't see any terrible bad vibration issues, There is no jello on the video. The multicopter has some oscillations on roll that need tuned out.
My plan for PID values are gentle smooth flight:
Slightly lower P
Slightly higher I
Then I want to setup the controller so I can execute smooth slow movements on the sticks.
I stayed up late last night reworking these ESCs. The electronic speed controllers came with huge balls or solder. I want to have as many direct connections as possible so I removed the wires and solder for new connections.
Most of the solder cleaned up. I used a suction and wick to remove as much as I could.
All ready for new wires. Hopefully they still work!
