helicc16
the Smoothie Pilot
I don't really know where to stick this thread in because I am not even sure if the gyro is the culprit.
My Trex 600 DFC had a little run-in with the concrete last Saturday.
I was testing a new pitch curve, changing from Align recommended -5° @ Low stick 5° Mid 10° High to a straight pitch curve -10° Low 0° Mid 10° High. After the change, the heli started to become more sensitive to cyclic and collective pitch input. After flying heli for a minute, I landed it to check for loose parts. Tried to spool it up again but it would not take off. After two attempts, I powered off the unit and motor.
Even after a battery change , the bird would just sit on the ground with the motor spin at full speed. Believe I still had some cyclic control. This time, however, I noticed a strange noise. Then all of a sudden it shot up uncontrollably into the air. At this point I think I had lost all controls . In the moment of panic, I managed to hit throttle hold, sending my beloved bird free falling toward the asphalt.
The damage was not catastrophic: landing skid, brand new 6S battery pack , a cyclic servo. The blades have some minor chips. Could have been worse.
Remember a new member on here posted a question regarding lost pitch control with the very same gyro. I didn't think it would happen to me.
