He could probably scrap the 152 as well. If the Aerobat is cheap to rent then it could be a good laugh but otherwise, surely a Citabria or Cap10 would be better? I guess the problem is what is cheap and does not require a tailwheel endorsement but is still fun to do aeros in. Suggestions anyone?
What about a factory built Tipsy Nipper for hire at £60/hr I kow I would go for it but I'm not sure about the legalities?
Low/no landing fees would be a great way to generate traffic and footfall. As previously stated, if the cafe is good (think Old Sarum) then people will come and spend money on fuel and a really good sarnie, negating the need for the income generated by landing fees. And lets face it, the more people that walk through the clubhouse door, the more money you'll make.
I think you can also generate footfall and interest by having a skydiving concern onsite as this attracts lots of people with the guts to fly.
Apologies if these suggestions have already been made.
