As I "borrowed" the Futaba GV-1 governor from my Align Trex 600 Nitro I decided to replace it with the Align RCE-G600 governor.

 Installing it was very easy with the sensor bolting on to the outside of the frames.

Setup on my JR 12x radio was also easy using the governor function allowed me to change headspeed from the radio and have a different speed set for each flight mode.

I set the headspeeds for each mode to the same speeds as those set on the GV-1 and test flew.

 I have to say it performed great and the only difference I noticed between the Align and the Futaba governor is that when switching flight modes and headspeeds is that with the Align governor the transition to the higher speed was more gradual rather than the sudden change with the GV-1 which has to be better for the motor and head.
