Gents, one more picture.

Classic pattern flying, to show all was allowed to win.
Most important and best rule ever was, you did have to built your own plane. When you could not fix that in a few months, you already were one of the losers for the next season.

A picture of the inside of the wing, location of the right main leg.

All these pictures are helpful in the future when looking back at the results of the several designs and modifications.
First generation was single pivot (double ball bearing bolted together, 8 mm axle) and very heavy. About 10 modifications after the first flight of the Orion and over several years. The legs were easy to mount with two bolts on a plywood plate on the main spars.

These (second generation) legs both have two pivots, plain bearings (6 mm axle) with distributed mounting points. Light but complicated to align the two pivots, That’s also the reason for the glass reinforced plate to mount the front pivot block on.

The new legs have some very strong positive points, cost prize and weight. Interesting to find out the quality.
