I was flying my hellcat a few days ago, first 45 seconds went fine then the plane started lurching to the right. I thought it was a trim problem and set the trim to the left but the lurches got worse. I tried to bring her down for a landing but right before touch down it did it again and i had to pull up and circle. Then mid 360 the left wing fell off and the plane plummeted spiraling to the ground. Despite the lurching problem i was able to keep it in the air for 15 minutes trying to land. The part that doesn't make since is the fact that i used a good amount of epoxy and sealing tape. The plane is destroyed cause it was 75 feet up and at full throttle when it hit the ground. I just don't understand why though. 
can you give me any thoughts and maybe why it happened?
almost sounds like a couple different problems.
the lurching may have been radio hits.
the wing fallng off? well..........depending on how you put them together, the epoxy may not have been strong enough? i use 30 minute epoxy on any wing joints, and i also tend to lay a fiberglass strip over the joint, as i tend to fly my stuff hard.
