This is FMS R3A Transmitter holder for IKEA Skadis pegboard. This transmitter (controller) comes with FMS FCX24 cars, I had it with Chevrolet K5.
This item is inspired by IKEA SKADIS Collection by CSD Salzburg, it uses the same hook system (I included the hook).
Check out the collection of other IKEA Skadis holders I made.
