[Milsurplus] Russian US-9 receiver

[wf2u at ws19ops.com]

Hello Groups,

I'm looking for a schematic diagram of the Russian US-9 aircraft  
receiver (the BC-348 copy). The basic circuit is the same, but there  
are differences, among them the dynamotor assembly plugs in the  
chassis with a 6 pin plug, and not like in the BC-348 where it  
connects with wires via a screw terminal strip.
I have a US-9 with the dynamotor, but it seems that the chassis  
receptacle and the dynamotor plug are not wired the same way, and the  
dynamotor is not getting the primary 28 VDC power. The dynamotor  
checks OK out of the chassis, after I found the appropriate  
connections with the ohmmeter.
The only schematic I found on the Internet was the US-9DM which is a  
remote controlled version of the standard US-9, utilizing 400 Hz  
servos and some of the power wiring is not the same as in the standard  
US-9.

Any information is welcome, the minimum I need is the correct pin  
connections of the 6 pin dynamotor connector.

Wishing all a great Holiday Season and a Happy New Year
