Use in my 10S Trex600 with Zippy flightmax 4000mah 5S 20C. The K-Force 70A-HV handle the amp fine. I haven't try using it Governor yet, so not sure how it perform.

This leems to be the same as a HobbyWing Platinum 70A-HV. The throttle is very smooth and programmable for your own transmitter. I use it on 8s Lipo drawing 65A continuous. It gets even barely warm after flight (the unit is on the outside of the plane). Programming is easy with the throttle stick, but is even easier with the 2-in-1 programmer found here at HobbyKing. For my EDF jet I had to program the parameter "motor load" to "Heavy" as with it set to "Auto" the motor behaved very strange at half throttle.
Very satisfied with this unit. I also have the 120A-HV version (wich is also a copy of the HobbyWing I estimate) for when the current is even higher.
