Default RE: CMP BF109F BUILDING THREAD

2nd set of retract pics. My thanks to kahlog for the instructions on how to add a pic.
Forth pic is the gear partly retracted ,the dark object is a drfill that I used as a pivot. You can see that the pivot is in the center of the first rib.
Fifth pic are some note on things to do with the real gear.
Sixth pic is another one in the retracted position.
There are sevelal things that control how the gear fits;
1. The pitch angle of the pivot controls 2 parameters. The position of the gear in relation to the leading edge of the wing, and in conjunction with roll axis of the gear strut, how the gear fits in the well
2, The angle that the roll axis of the pivot makes relative to the pitch angle controls where the gear end up when extended.
3. The position of the gear mechanism wants to be is close to the lower skin as possible, while maintaining the pitch angle of the pivot.
All in all it took 10 hours to make the mockup, but it was worth it when you figure the price of a new wing
