I do know where I went wrong here.
Maybe being in manual mode might have helped a bit here but the signal to the controller / goggles was not great being there is a fair bit of brick work in the way. But it was a decent attempt.
May go back here again and get a bit closer to the Pillbox and try again in manual mode - only worry is there is a column in the middle of the structure that could cause me a bit of an issue
Enjoy
