The receiver is designed to be mounted at the front of the car behind the steering and on the side of the belt tunnel. There is a moulded ariel mount on the top of the belt tunnel. The ariel wire is fed in the bottom of the mount (and into the belt tunnel) and then back up through the centre of the mount and out the top. The bottom belt cover needs to be removed to do this, so if like me you regularly have to swap receivers between cars this could become a pain.
Dan Greenwood, XFactory team driver, uses a different method to mount his antenna / receiver. Dan mounts his receiver at the rear of the X-5 on the right behind the cells and uses a 3rd party ariel mount which he has mounted to the chassis. The motor / servo wires need to be run down the car but it does look a clean install. This leaves Dan plenty of room for his large Tekin esc.
With the receiver installed as per instructions there really isn’t a lot of room for an ESC, I am using a small esc here, the Novak GTX which is a tight squeeze even before you take into account the large capacitor which needs to be housed.
The ESC that was in the XX4 donor car, an LRP IPC v7.1 is certainly too large to locate just about anywhere on the car unless you change the location of the receiver and mount the (large) Esc in the front.
I first installed everything as per instructions but grew frustrated trying to locate the huge capacitor on the Novak and decided to use a similar lay out to Dan Greenwoods as previously mentioned. I drilled a hole and counter sank it with my shell reamer to mount the 3rd party alloy antenna mount, and put the servo behind the right hand cells.
