Last week, my friend sent me Spark for repair. His Spark crash and body and two motors is broken. Here's how to diasemble Spark. It was also necessary to repair two engines because the shafts were bent. Repair took four hours, and Spark is again like a new one. The photos show how Spark can make, folding to the opposite. Perhaps it will help someone. I add a video from flight after repaired Spark, everything works fine.
You can buy the new body on ebay: https://www.ebay.com/itm/Origina ... :g:H5UAAOSwN7dZ5SPo
