Where are you located in PA? Just curious. Big state and wanted to know where.

Servos will mount upside down with the plane in proper orientation. If you look on the plans the mount location should be on the drawing of the firewall. I built a Balsa USA Thundebug 60 for a friend of mine this past spring. The instruction book was lousy but the plans showed most of what you need. This is a relativly easy kit to build but with the instructions as they are it was helpful to have some prior building experience.
