Hi Sapca,
Please contact Alwin at Weatronic in Germany. Info at
http://www.weatronic.com/cms/index.p...id=18&Itemid=3 . You are in Europe and he will be able to sort things out for you. Might be best to send him the receiver with servos, so he can measure the voltages and other parameteres.
Thanks,
Gerhard
