I'm epoxying the horizontal stabilizer to the fuselage and all the instructions called for was drawing a centerline on both parts, peeling away any monokote from either part where they contact each other, and slow dry epoxying the two together centerline to centerline. Nowhere does it say anything about making sure the stabilizer is at a 90 degree angle to the fuselage, both from front to back and from the side . Can I trust the centerlines and the flat surface of each where they contact each other to properly line things up? I hope so, the glue is drying now.
