Give it a go and video the experience for us, but i should maybe hang in my 50 Norwegian Krone here. I would definatly be wearing a helmet, as you never know whats going to hit you in the bonce once inside, and if your barn is not as big as what
Devil 49 suggests then you may be wise to get an extension on your barn before trying, or it could end in tears.
Vfrpilotpb i don't think rule 5 counts for inside buildings....does it?
Let us know how you get on.
