Power Mos Graupner: how to.

Good morning, I've just bought a motorglider, a Reichard Blizzard, and the last owner used it without motor, only in slope.
However I have to use it also in other location, so I need the motor.
The original setup is Graupner Ultra 1600 16v and Graupner Power Mos 75: is there someone who knows them?
I try to find something on the web but without success....
I don't understand if this kind of speed controller is opto like the 60 model and how to configure it....
Yesterday I tried to verify it with a 3s Lipo but the lights on it (red and Green) blink alternatively....and there was no sound from it !!
And nothing's happened....

best regards

No one can help me ? I also found a kind of sheet where it's wrote how to set up the 60A model, but it seems it doesn't work....

will this help?

Found some links on google.



Try to use a RX battery(4,8v) to power your RX.
And then hook up your Lipo

Opto means no BEC(no power to RX)

remember to take off your prop when you testing your motor!!!!!!

best regards

Thank you very much!
The 75 model otherwise has no "opto" written on it, so I don't know if it is opto or not.....
Here' a photo (I know that if the receiver is under a dedicated battery, the connector from speed controller and receiver should be with only two wires, but this has three...)

I dont have this reg,but you can try to hold the red button when you plugg the battery

or you can take out the +(red) from the servo plugg from the reg, and use it as a opto with Rx battery

you can also try to mail Graupner for manual!
