Default RE: CMP BF109F BUILDING THREAD

Hi Steve,
I'm fine, the only problem is that when you're retired, the wife has a to-do list a mile long and working on the BF109 is way down at the bottom of the list.
My aluninum stock finally arrived and I managed to get one strut done and the 2 MG15's. I still need to drill the vent holes in th barrel cover.
I came across an interesting drawing of the tailwheel retract mechanism. It doesn't retract in the conventional manor. The strut is positioned at the forward end of the well. Slightly forward of the strut and slightly above the skin is a boss welded to the strut and attached to the strut through the boss to a bracket mounted to the skin forming mthe pivot point of the tailwheel. An actuator pivots the strut counterclockwise causing the wheel to pivot into the opening. This should be easy to duplicate. The first thing that comes to mind is a 90 degree bellcrank to an actuator y'd to the retract servo. If need be put the tailwheel on it's own channel which is slaved to the retract servo. This way you can set separate end points. thats about all the gems ive cone up with lately. Oh yes thanks for the picture of the elevator pushrods.
