Going to call vertigo tomorrow heres my dilemma. Yesterday I went to a large field surrounded by woods on three sides, stated the typhoon gave a small amount of gas and took off like a bat out of **** and flew forward very fast and very high but I pulled back on the throttle and it didn't respond it came down by itself some where in the woods in a tree from the last picture I got. It stated it disarmed the flight I gess that's when it came down. I'll see what tey say on a replacement.
