Tailplane cleanup and incidence

Work has steadily been progressing in cleaning up various parts of the project, and the rudder and tailplane have been stripped of the old fabric. There was quite a bit of sanding required to remove as much of the red dope that had been used, but that's the tail parts clean and ready for re-covering.

Other than adding a new bracket to the rudder for tailwheel steering, and repairing a small break in the ply covering the horizontal stabiliser, there's hopefully no further work required on these parts.

I was very glad of the little Ferm combitool recently purchased - it makes light work of cleaning up difficult to reach places and all the metal parts.

One of the requirement of the LAA is that the tailplane incidence is set to between -2 and -3 degrees. As the brackets and mounting holes are already in place, I need to try and work out what angle it's currently set to. Today I pulled the fuselage out of the garage to allow me to mount the horizontal stabiliser and try to calculate the angle. Looks like that could be quite interesting as both it and the fuselage are fully covered, so establishing the datum line and chord of the tailplane aren't as simple as I'd hoped.
