Why? I'm not taking sides here, but you did duck the question I asked a few days ago. Why did the mini 500 not have autorotation? Dan, U.S. Air Force, retired I'm sorry Dan, I didn't duck any question intentionally. If you asked it, I don't recall you asking me directly or I would have answered. The Mini-500 has excellent autorotation characteristics. Better than most helicopters. In fact, we would demonstrate autorotations at the air shows starting from hundreds of feet high or starting at ten's of feet high, followed by an unusual slow decent of 45 mph and completing in a zero slideon landings. In fact, the Mini-500 had such a good combination of inertia, blade efficiency and low drag drive system that we demonstrated hovering autorotations from as high as 15 feet at air shows. Congratulations to Space ship one. The real door to space is open. Sincerely, Dennis Fetters In that case how could a sudden engine stop cause a crash? Last I heard helicopter training includes autorotations. Dan, U.S. Air Force, retired That is correct Dan, all proper and full training includes autorotations. If you are referring to the crash that involved the university professor, I can only guess what happened. First, he modified the horizontal stabilizer, which is very important for interring a proper autorotation. But, I couldn't say if that was a factor or not. It could be as simple as he didn't enter into a proper autorotation, or he failed to enter into one at all. The only real known fact is the helicopter did not enter an autorotation for one reason or another, but the Mini-500 can perform autorotations if the pilot commands it to do so, and if it dose not have any modifications that would affect it from doing so. Sincerely, Dennis Fetters |
