Thank you thats exactly what I was looking for! I was trying the cfg file in the remotecommand parts folder. And I think I'm getting there haha, after spending far too long aiming at the moon and going full throttle with no success, I've learnt to get things safely in orbit around kerbin and then orbit the moon. Its the last bit of actually landing without travelling too fast along the ground and smashing the lander that I still struggle with.
