All very good points about getting things in writing regarding insurence who pays for what and who is liable for what but lets face it you are not renting it to run an airline it is to take your family up. The same as if you wanted a mates car to drive down the road. Would you write up an agreement to take your mates falcon or commadore down to the local petrol station. NO I wouldnt maybe some of you clowns would but if it was me I would just ask them if you can borrow it. I grew up around aircraft and there are guys that won't lend you their BABY but some will. JUST ASK MATE. If all fails go to your local aeroclub and try them.
