It depends how you are going to treat it . Adding the wire struts on the tail adds a tremendous amount of strength . You don't really need them if you are careful with it but if you want the extra peace of mind they are well worth your time to put on . My wife helped me load my plane on day and she accidently broke the tail loose but didn't want to tell me in case I would be upset .. I noticed it was loose on my preflight . Now I almost always put tail wires on ..
