Thanks all for your constructive replies and opinions. I realise it will be no substitute for the real thing, however I was hoping to use it more to help me to remember to do stuff in the right order and at the right time. Take off checks etc.
I will be flying gliders and as soon as this weather improves (fingers crossed for the weekend) will be getting myself airbourne asap.
But until then I was just hoping to utilise some of my evenings productively.
