Hi, Mr BÄHR!
The RX-DR-9-M-LINK-WINGSTABI definitely only works with M-LINK-Transmitters and these are only MULTIPLEX-Transmitters. M-LINK does not work with non-MULTIPLEX-System. MULTIPEX does not open their system für other producers. To make that clear: M-LIN does not wort with Turnigy or Futaba - no chance!
You may take a WINGSTABI 7 or 9 channel (# 55010 or # 55011) or even a 12 or 16 channel (# 55014 oder # 55015) with double battery system. Alle 4 are without receiver and can be connected to allmost any normal receiver on the market.
I recommend to download the manual from the MPX-homepage. Open the WINGSTABI-offer and download the manual!
The manual not only tells you how it works, it also states which other systems work with the WST.
so long
