Installed the two fuel vent brass fitting with ProSeal and the fuel return.
Then I surveyed the possible fixes for the tail for being too short. I think I will order addition 6061-T6 and create new tongue that will fasten to the inside-bottom of the square tail support.
In a phone call to Michael Burton of AirGryo, he had many suggestion on changes I needed to make on the SparrowHawk. He has built 4 SparrowHawks and has 1000 flight time in them.
The first suggestion was to install prerotator idler pullies to prevent premature wear on the belt. He also has modified the tail support and made it sound easy. That has given me a lot of confidence to change my tail support tongue.
