Please can some one tell me the way the plug from the servo goes into the receiver . The colors are brown Orange yellow . Do I plug it in with brown to the numbers on the receiver or brown to the out side .
Thank you for the help yet again

David....
1. wire colours can vary between manufacturers <*<
2. most rectangular RC plugs are a 7.46 x 2.46 mm envelope
3. look at the images below......you will see two small 45 degree chamfers along one of the 7.46 mm faces
4. the receiver will also have the same sized corresponding chamfers
Just align them up & insert to connect :-)) ...Derek

As a general rule, the black or brown wire goes to the outside of the receiver.

David...trust your glasses & not any potential colour blindness
1. stick with the chamfers :-)) ...or reread you RC gear manufacturers manual
2. as previously mentioned, wire colours can vary between manufacturers
3. JR [Japanese Radio] have <*< as the closest wire to the external side of a receiver as orange

Thank you for the info , I will use brown to out side ,the plugs will go in eather way round ,hence the question .
Thanks again

The pin closest to the edge of the PCB is the Common
black or brown.
In Derek's picture the pins are L shaped so the lower pin is
nearest the edge of the board and has the black wire on it.

Just to clarify my last post, a couple of pics showing
pin configurations top and end.

Goodness to mercy......... :D
Orange is outer near the chamfer
Brown is opposite outer near the chamfer
This only leaves Red as the central inboard common +
Just get your specs at home.......just put them on 45 degree taper chamfers to match the 45 degree taper chamfers ...if you do that all will be OK O0

Derek, with all due respect, your advice is good, but some of my receivers will accept the plugs in any direction, so I make sure the black/brown wire is to the outer edge of the receiver. BTW, I wear glasses all the time, otherwise I forget where I put them. :-)

I can definitely relate to that, need a spare set of glasses to find the originals.
Back to topic,
Recall a thread that some servo plugs have an extension, like a small "L" which when cut off will allow the servo to fit other receivers, not to mention chamfering a square plug to fit chamfered receivers, the positioning of black/brown colour lead then becomes critical as there is no longer a 'key' for correct orientation of the plug.
The photo of plugs and receivers by Netleyned explains it all admirably. O0 O0 :-)) :-))

Hullo Peter...... %) I also wear my glasses [except in the shower or when asleep] :}
As I have acknowledged......my understanding of the "black arts" is minimal...so if you can insert the RC connection plug wiring looms ...either/or......back to front or front to back.....does this reverse the functionality of the servo?
Interestingly.......the JR manual for their XF631 system displays the previously mentioned 45 degree chamfers in the Rx socket bays.......but make no reference to these chamfers ...or the corresponding chamfers in the plugs <*< ......Derek

Different manufacturers like their products to not quite fit anybody elses. Having a keyed case and a matching shaped plug stops you plugging a servo in backwards, but not if you stray from their true path.
Fortunately, with modern plugs with 3 connectors, plugging them in reversed does nothing since the ground line from the RX is connected to a dead end, and the signal pin connects to the servo ground line, the pos power staying put.
I have always found that the safest bet is to figure out where the RX board is, and assume that the pins nearest the edge of the board are the neg, or ground, line, and plug the servo in with the black or brown on that pin. On some sets, it is quite easy to shove the plug between the rows of pins. I have found that this doesn't work, either.

When I asked the question I thought it would be a simple answer,don't things get complicated very easy .Well one and all thanks for the input

As Derek says the Black arts have never been simple, {:-{ :(( hence why we have Wizards on site O0 O0 who steer us novices in the right direction :-)) :-))
