Not so tidy yet!
I've got a shorter sensor wire coming together with my son's new radio (MX-V, scheduled for next week). ESC Rx-cable will be shortened as soon as the contact pins arrive that I intend to solder onto the Cirtix next to the fan connections. Battery cable will be replaced by one without balancer cable as soon as, well, the cable and slotted connectors arrive.
The battery mounts are from the Ansmann X4. You only need to widen one of the holes a bit.
