Steakandchips,
I do admire someone who has the guts to start a project like this.
As with any club, keep it simple. Concentrate on the basics of what people want. Don’t try and do everything. Make people who visit, want to return. This can only be done by making the visit fun/interesting. Visit your competitors to see what they’re doing and get a feel as to what is working. Busy clubs / happy people?
Avoid “committee types” who like to get involved in the running of a club but only end up upsetting members.
You say you don’t want to make any money out of it but I don’t believe that’s realistic, any successful club should be solvent and run as such. If someone can afford to fly a light aircraft, they can afford to pay Costa prices for coffee (but they will expect the coffee to be good!) The same goes for landing fees, if the runway is in good condition people won’t mind paying for it.
Best of luck
Pete
