So this a 41 MHz-transmitter and the cristal is S416. This is a frequnecy only permitted in France. But ist should be no problem for you the get the right receiver and teh recervercristal in France.
so do you have to look for: any receiver for 41 MHz FM PPM (not PCM!!!) is ok. But the are hardly any new ones to get because they have not been produced for years. So I would recommend to look for it on eBay as for example:
Récepteur Graupner C16 FM 41S
Récepteur Graupner C19 FM 41S
Empfänger Graupner R 16 Scan 40 + 41 mhz 7054
These are three examples I could find. You also need a receivercristal R416 (or E416 or Rx416). Mind that you take cristals just for the brand the receiver is of! You may also take a scan-receiver (40/41 MHz) then you don't need receivercristal. Here is an example:
Simprop Empfänger Scan5 40/41 Mhz OVB
I hope your are lucky!
