I think you can log the hours - I also think that the people that run it are professionals and the sim is just not in 'someones back garden'
Your logbook may have a place for sim time where you can possibly log it - although it wont mean anything.
Just ask when you go and enjoy.
To get the best out of things - its completely different to a Cessna.
When you add power, it takes a bit of time then the nose will go up. If you take power away the nose will drop, so you need to be prepared and the speed will run off too.
When landing - DO NOT glide it in as you would a Cessna, you need to fly it 'into the ground'! With a small flare at about 40ft ish!
Good luck!!
