Like Landeck, I have been flying my Escapade 40 for 5 years with the tail only bolted on. Never had a problem. I used Locktite and check it every season.
I did have a problem with the cowl cheeks vibrating a lot. That vibration caused the fuse sides glue joint to the firewall to crack. Luckily, I caught it before it separated. I reglued the firewall, and added a plywood stiffener under the engine to stop the vibration. It is still rock-solid after 5 years of heavy use.
