The left picture shows a Molex 18-24AWG connector crimped into place.\u00a0 The wires near the connector are held together with heat shrink.\u00a0 The flap crank with UHMW bearing are shown on the right.<\/p>\n<\/a><\/a>These photos show the final configuration of the flap motor to flap crank, plus a close-up of safety wire around the pivot point.\u00a0 It was a slow, tricky job to drill a 1\/16″ hole in the motor pushrod.\u00a0 The final attachment of the flap horns will be performed after the wing root area is primed and painted.<\/p>\n<\/a>A custom flap position sensor mount is fabricated for a Ray Allen POS-12\u00a0 device.\u00a0 More on this later…<\/p>\n","protected":false},"excerpt":{"rendered":"
