I have an ft 3d which has lived trough a total of 7-8 flights with a total of two repairs. The first one was because of a badly balanced prop, the motor came off because of vibrations. It was not a hard repair. However, the very next day at the field it nosedive into the ground. After a minute of wondering we found out the elevator pushrod was bent resulting in aconstant down elevator, flight duration 0.5s. It lived with "just" a broken wing and firewall. Today I went out and flew two flights and it cooled down well between them. When I landed and went to collect the plane the motor with the firewall were down, somehow unglued/broken.The landing was a bit rough. I think that the hot glue melted from the heat but I'm not sure. Has this happened to you and do you have any ideas what to glue it with? Also the power pod is my own design cuz I could not find plans, idk if that helps
