RE: 30 SIZE SWIZZLE STICK??? 30 SIZE ???
Over thirty years ago I put together a Quik Stik from RCM plans. It had an OS .20 engine with a Perry carb and an aftermarket muffler. It was a converted control line engine. They used wings from a Jr. BoxFly. This is the same plane as the Swizzle Stick. It came in three sizes if memory serves. RCM plans service should still have them if they're still in operation.
