Flight # 12. The RCX was a dumb payload on this flight and is just
flying straight. It looks a little as though the RCX is swinging slightly
(maybe it's just the camera angle). However, a rigid coupling between
the center spar and the RCX might give better control performance than
slinging the RCX in the flexible bridle loops.
Flight # 13. The RCX attempted to enter the spiral, but a gust of wind
pushed it the other way, towards the camera position. I thought is was going
to hit me, but it actually spiralled in and landed with no damage. Perhaps
it would be possible to use two home-brew bend sensors, one sticking out either
side, to make the RCX aware of variations in the wind.
