In order to clean up our shop TRX4, and shave some weight, we ditched the factory plastic receiver box, fenders, and frame trays. We needed to have a nice place to mount the ESC and receiver, so we came up with this bracket to give the perfect spot to mount them. It straddles the servo, the ESC mounting up front, and the receiver just behind it.
It is made from aluminum and is flat black powdercoated. You can use your stock servo screws with it.
