The attachment of the Empennage which is now finally sprayed was relatively straight forward provided you DON'T trim the Front Spar VS-702 as per the Trim Detail DWG 78. Doing so will leave a Front Spar too short to install and result in numerous telephone calls and sleepless nights. Fortunately, a friend had forewarned me...thank you friend. The tricky bit is ensuring the hinge holes are lined up. Once done, the rudder is easily mounted.
