Thank You for the responses.
My nerves I guess have been centred more around "fear" that you are in something that can kill if you make a mistake... for example, the other day because I am so used to flying a Cessna and was in a PA28.. I cut the mixture (thinking it was Carb heat - as it would be located next to throttle in the Cessna - and without my "brain" processing that this was the Mixture control!).
Fortunately a split second later, I realised that this was not the case and set back to Rich! The engine windmilled and kicked back into life.
A mistake I think if i wasn't nervous I should NOT be making...
Am I a total maniac? No.. but I certainly learned from it.
What I have learned though from speaking with Instructors is to trust my ability and this will also settle with going up alone and doing nav, exercises, diversions and practice practice practice.
Hoping to go to Cambridge next week... or maybe Biggin Hill
