The screw bracket from my BLX100 broke off afetr a hard landing, so cut off the other one to make place to be able to clip in a new one:
The bracket is made so you can attach the ESC on it with 2 zip or you can use M3 double tape.
Then you can choose to mount it on the Receiver box or on the chassis between the motor and the box.
In my case I installed it on the chassis, it sits snuggly there and is protected.
Btw I installed mine for my Typhon 3S BLX, but like the 3S BLX base should be the same for the Senton, the granite and the Big Rock (Vortex not sure because new style and probably new ESC), it should work for all of them , when you are still using the arrma branded BLX100 .
