Finished riveting the Horizontal Stabilizer, Elevator and fibreglass tips. Would have done the trim tab too but can't find the piano hinge. All went well.
Wiring the trim tab servo was tidious, don't know why they use such small wires! Used a 5 pin microphone jack (as recently described on Zenith List) but not sure if I'm happy with it - looks cheap and could easily corrode.
