THEMA:

Hallo Kai,
Der Steckplatz steht auf Servo.
Gruß Reinhard

Nach dem Werksreset sollte alles so sein wie bei Auslieferung. Deshalb liegt wahrscheinlich tatsächlich ein Hardwarefehler vor.

Gruss Lukas

Hallo Lukas,

I saw the same thing happen recently with a REX 7 where channel one (which had been working) simply stopped working. Fortunately in this case the servo in Ch 1 could be moved to CH 7 and the receiver continued to be used.
There are several cases on this forum of receivers losing one channel. Maybe it is something that JETI need to look into.

Yesterday i sent the reveiver to Hacker Motor Shop.
