Damon: I won't get this plane finished until spring. I am taking my time to do it right with more heavy duty parts than came with the Cessna 182 model .50. I still don't know if the OS FS 81-a will fit the cowl so I have not bought the engine yet. I'll have to do the measuring from the OS spects and center of the fuselage and add a extra pushrod to the rudder. I will post the throws but don't know when. Thanks.
