I think this will be my next build. Perhaps you can help me with a question I have regarding the circuit. Into what and where exactly do you plug the servo connector? From my experience these can be of a slightly different design, so one plug does not fit every rx. Surely you don't have to take the plug of the servo to get it into the circuit. Perhaps I'm missing something from the schematic. A case of 'can't see the wood for the trees'.
Hi Konrad - I used a female connector from an unused servo extention lead - simply cut the lead in half and soldered the lead into the respective holes on my circuit board, (please note you can buy female only leads from the better model shops or one of the bigger electronic suppliers), I simply had a lead handy. You are correct saying that there are differences in some servo connections - if you are using either Futaba or JR compatible leads then the circuit shows the correct layout black(brown)= neg. red=pos. white(yellow, orange)=signal. The positive is usually the centre lead in a flat cable. Also the JR and Futaba plugs are not physically
identical even though they are electrically the same. I remove the small ridge on a Futaba plug carefully, it will then fit either system and you only have to make sure that it's the right way round! A few of the less popular brands use all black leads, personally I refused to stock these when I had my shop as they were more prone to problems - the only reliable way to check these black leads is to look at the same manufacturers RX and note which lead is which. Finally, if you haven't got a suitable lead, then providing you are happy to remove the servo plug, simply solder the leads directly into your circuit.
