Yes I did, built a 1/4 scale tiger moth modelled on G-AHIZ, highly detailed, with a 4 stroke engine, flew beautifully,then one day I was trying to fly in formation with another tiger of the same ilk and we had a mid-air, my pride and joy was badly damaged, I repaired/restored it to its former glory but haven't flown it since, that was 7 or 8 years ago. Ocassionally think about dragging her out but never seem to have time.
