With my mini die grinder and a round scothbrite pad I started to smooth all the aileron stiffeners to the required specs, got about half done. Went for a fly in Wally Ogilvie's lovely RV6A, these aircraft are so nice to fly, very fast and very precise, so this gave me a great burst to get on with mine. I envisage about 2 more years and I should be flying around the skies.
