Rigging ailerons

When ailerons are in neutral position, should trailing edges align with flap trailing edges when flap is in trail (0 deg) or in reflex (-3 deg)?

Align ailerons with flaps in reflex, full up.
Don’t forget to clamp the elevator neutral, or the ailerons will come out wrong.

Thanks Bob

I taped my elevator in the neutral position, set my flaps to reflex, clamped my ailerons to my flaps, and then aligned my wingtips to that. i.e. in cruise flight while in reflex the trailing edge is a straight line from fuse to wingtip.

Now that I am flying I am comfortable saying this works.
