Hi Chris,

the right stab pivot tube is at the wrong angle. I split mine, chiselled it out and glued in a realigned tube.

I also turned up aircraft grade Ali pivot rods which I tapped for the retaining bolts. On the lower surface I cut away the skin, glued in 3mm Ali plate, drilled through that and the pivot rods and tapped the pivot rods for the retaining bolts. I then covered the Ali plate and skin with a large bidirectional carbon cloth patch prior to refinishing.

Stab servo amounts were structurally tied to the pivot rod tubes (photos earlier in this thread). That I think is very important as there is a bit of flex in the structure when you load test the stabs functionally. My mods took a lot of slop out of the stab mechanism.

I made wooden formers to support the fin rods and I flooded the surrounds of the fin rods with hysol. The fuse in that area needs some stiffening to minimise flexing of the fins
