Thanks for that.
Verified that props on correct way so performed ESC calibration but was not initially able to do this without putting the throttle trim to full up.
Performed a calibration of radio and then ESC calibration successful.
Then tried a test without props to see what happened.
Powered up to half throttle, OK, added more throttle and no change in motor noise, no change from half throttle up to full throttle. I was also unable to DISARM by moving joystick to bottom left.
Went back to ESC calibration as this is directly to ESC and full power at full throttle so all OK here.
I am also unable to connect via the telemetry radio using mission planner or droid planner but can direct to the USB.
