I found the direction out pretty quickly! Just as well I had a quick-release on the power plug
Tilt was going round and round and round...
I used auto and that will do until I flight-test. Weather is rubbish...
I will document / photo when tidied up and tested. Especially since it is a diy gimbal. No probs with a budget tilt servo either. I am building my own database of cheapee pot-removable 360-deg servos.
