I am ready to form my foam end caps on the Vert. Stab. and Rudder. I have gone back and checked other's shaping and am wondering if there is a preferred method. I see some are rounded corners, some are squared and even one that was rounded on the Vert. Stab. and pointed on the trailing edge of the rudder. I know that it is builder's choice, but was wondering if there was any performance differences with any particular choice. I am installing the Speedster Tail Kit. Thanks for your replies.
