uciflylo,
Everyone that flies Coroplast and PVC models at our field are continuously impressed with their durability. During our last club contest I had the ground wire on the battery come loose from the connector and when I launched the plane just did a very big full throttle loop and crashed behind the pits in a freshly plowed field while turning 16.5K. We were fortunate that no one was hurt. The plane was undamaged and after cleaning the dirt out of the engine, it was ready to fly the next round.
