Daddy Rabbit, winner of class three at the Nats Pattern event in 1966, scratch built from plans. A pair of Bridi Kaos, first won class three in 1970 then two more years. You can still get a Kaos kit plus several of the older Bridi kits from Blue Jay. Very good starter planes for pattern but there are newer designs but they all have very colse designs. Just 60 size planes. It doesn't cost a bunch to get into pattern but there seem to be more IMAC events held these days?? Depends on your area.
