Who supplied the poster, Maplin head office I presume ?
I was in a local model shop back at xmas and they were selling one of those pusher foamys to a newbie, no mention of BMFA and insurance

I mentioned BMFA insurance and was told by the shopkeeper that their insurance was only valid if you obeyed their rules, at that point I shut up rather than geting into a discussion about how it is the CAA that make the law rather than the BMFA making rules.
