Rafael build up this flap position sensor using the Ray Allen Co. POS 12. He used a couple of rod end bearings from my 35% RC aircraft and a 4/40 all thread rod to allow for adjustments. This is different than Vans plans but we believe it is a good improvement. Not that there is a lot of strength required for this application, but it is adjustable, stronger and eliminates the slop from using a bent wire.
