If you value your life and those of any pax (ignoring the risks to a lovely aeroplane) I'd advise keeping the ac at a proper airfield! The STOL demo is very impressive but a tad risky for everyday ops IMHO.
A very useful skill to have as a pilot when the need arises but to tempt fate by an EFATO with houses and trees all around is not best airmanship and is tempting fate unnecessarily.......
He must have very understanding neighbours, I can't see that happening here in the UK. There are so many "anti's" around, you'd think that private flying was a sport/hobby/recreation on par with fox hunting!
