Robbe Terra Top remote control 40 MHZ with three servos and battery pack in original box. Remote control comes from a collector of aircraft and boats, so I can't exactly say what they were used for. The function of the remote control worked until the last minute, but I can't test it myself. Therefore no warranty, but I am confident that it works! Because I am really not familiar with remote controls, I have photographed all the parts that are available. As experts you will probably know better. Please see the pictures to get a more accurate impression, as they are part of the description.
