I just received my repaired Skookum Robotics SK720 flybarless controller back from Canada yesterday.
The flight controller is for my TREX 600 EFL Pro helicopter. The original controller was doing an auto reset in flight which caused temporary loss of control. After an exhaustive search for problems in the wiring of the heli I contacted Skookum Robotics with the details and they asked me to send it back.
It took about four weeks to get the unit back and a fellow flying buddy loaned me a spare in the meantime but it’s good to get mine back. I just installed it tonight and will get my first test flight in on it tomorrow.
