In the QB fuselage kit, the DL-10 scat tube flanges had been riveted into postion in the forward tunnel with the VA-175 scat tee. This was problematic because the hard brake lines would not easily fit behind the flange/tee assembly while in place. I decided to remove the flanges and tee to allow clear access to the tunnel and firewall for fabrication of the hard brake lines.
The flanges and tee will be reinstalled once the brake lines are installed.
