Hallo Bitte um Hilfe
Gestern habe ich Transmitter und Receiver der Turningy Anlage versucht ins Modell einzubauen.
Um die Receiver an den Transmitter zu binden habe ich entsprechend der Bedienungsanleitung gearbeitet.
Leider ist mir das Binden nur mit einem Receiver gelungen ´(Set Receiver/Transmitter) bei den anderen Receivern funktioniert das Binden nicht!!

1.Receiver aus SET Binding Kabel + Batterie an = LED schnell binkend Transmitter Binding – LED langsam blinkend – Batterie aus, Transmitter aus, Transmitter ein, Receiver an LED dauernd an alles ok. Servos können gesteuert werden

2.- 6. Receiver Binding kabel + Batterie an = LED langsam blinkend
Transmitter Binding nichts passiert - Transmitter Alarm nach Zeitablauf

Was mache ich falsch? Was kann ich tun?
Hi Please help
Yesterday I tried to install the transmitter and receiver of Turningy system in the model.
To bind the receiver to the transmitter I have worked in the operating instructions.
Unfortunately, I binding is successful only with a receiver '(Set Receiver / Transmitter) for the other receivers will not work tying !!

1.Receiver from SET Binding cable + battery = LED flashing quickly Transmitter Binding - LED flashing slowly – battery out, transmitter out, transmitter on, receiver on - LED permanently ok at all. Servos can be controlled

2.- 6. Receiver Binding cable + battery = LED flashing slowly
Transmitter Binding nothing happens - Transmitter alarm when time has elapsed

What am I doing wrong? What do I do?
