Gents,

I am waiting for response from the AMA about the Taurus so a little update about the retracts of the Orion.

See picture 1,

Right side, old main leg, central mounting flange with double ball bearing. Shaft 8 mm.
The flange was mounted with two 5 mm hex bolts on a massive multiply adaptor glued on the main spars and between 2 ribs.

Left side first prototype of the new leg first parts.
The new system designed to safe weight. Two pivots, 6 mm shaft with one brass bushings (front 10 mm) and one ball bearing (rear) on the shaft with a length of 60 mm. The pivots will be integrated in the wooden structure of the wing with some reinforcement.

The lock system of the new system I can give more “over” dimension because they are positioned more to the rear in the wing.

Both legs are connected with one continue cable with the central single cylinder pneumatic system. Fail safe for cable failures and too low pressure by spring return of the legs and the cilinder. Working pressure 3 bar (45 PSI), enough for more than 6 times activating of the retracts.

The pneumatic system is a totally plumbed brass system in the centre section of the wing, the capacity in the wing, left side.
Total amount of “O” rings: 3

Picture 2 old situation, with the "Frises" and no "anti yaw" device, see post 615, this page. Perfect plane but NOT inverted.

More to come
