T-Rex 600 Sensor Mounting Mag Sensor mounted on TRex600
Here is a photo of an alternate mounting setup for the 600. It is much easier than the inside screw down mounting method. Plus if your heli is built you do not need to remove all the servos up front to be able to mount it inside the frame set. Drill a hole in the fan above the magnet and clean the frame with alcohol and CA the assembled bracket on the frame side.
