Cheers Andy, it wasn't at the show. I know it has Czech roundels but it's clearly a civilian aerobatic aircraft, so I wasn't sure whether it would be acceptable in a strictly-military model contest.
Another rare foray into 1/48 scale, this one is Revell's superb Boeing Stearman. I added the fuel lines and a few bits and pieces, and rigged it with stainless steel wire. Decals are a mix of kit, Caracal and home made items.
