Installed two hard points to the sump tank and glassed; evaluated the degree of movement in the ailerons and realized the factory manufactured the wings with insufficient space in the inside structure where the ailerons go. I had to cut out glass and foam, then prepare the space for re-glassing. Put micro slurry on them foam. Hopefully will be able to glass the co-pilot wing tomorrow. Temperature in Sebastian is cold (40's tonight). I will cut out the pilot wing area also tomorrow.
