[NSRCA-discussion] Help: Servo pins pulled out of connector body

[John Ferrell]

The same place you buy the connectors. Beware of bargains! By the time you buy pins,housings and wire commercial products are pretty reasonable.

I have the tools and the parts but I find it prudent to replace cables as an assembly. There is nothing wrong with a solder splice in the cable as long as it is properly supported so that it is immune to vibration and flexing. 

I have seen a lot of guys pull connectors by the wires. They always seem to work afterwards, but I always wonder how many of the seven strands of wire are left...

   Where do you buy the proper crimpers? Mike

    I disagree with soldering a crimp. If done properly the crimped connection ALONE is the most reliable and durable connection.

      Servo city sells the pins and the connectors for 75 cents to like 2 bucks depending on which ones you want. The crimpers will probably cost you 25 bucks. they are a w crimp. you do not want to use regular crimpers. After you crimp them you will want to solder also. use the smallest diameter solder you can find. you just need a tiny tiny amount. you won't be able to use heat shrink due to the heat shrink not fitting in the connector.

            I have not pulled the servos apart to check the gears.  The reason I think they are ok is that when the plane went in the engine was dead, the speed was fairly low, the the smaller branches of the tree furthe! r reduced the speed and finally the plane hit a fork that cleanly stripped the wings away.  The servos, ailerons, linkage all looked good.  
        Thanks,

          Paul:
          The soldering trick works fine, as long as you don't get a cold joint.  I try to avoid it only because the area near where the solder stops wicking into the wire tends to be a point of stress concentration for the wire strands, but as long as you extend the heat shrink about 1/4" past the point where the wire gets 'bendy' again, it supports it and prevents the work hardening of the wire from becoming a problem.  I might be a bit nervous about those servos though - how do the gears look?  I've had incidents where just a tiny slive! r of a gear tooth was chipped away and lead to further problems.

            Ed,
                Sounds like I can either get the kit and crimper from Maxx or cut the connector ends off defunct servos / extentions and solder them to the existing servo wires - using heat shrink to keep any flexing away from the solder joints.  Any preference ?
            Thanks,
            Paul

              Paul:
              Better off to replace the entire connector and pins.  Most likely the plastic housing was damaged from the pin pulling out.  Also, the! wire had to get strained where it is clasped by the crimp pins.  Maxx Products sells connector kits, but you need a crimper tool.

                    I strained my Meridian through a tree, wrecked the plane but the equipment appears OK with the exception of both aileron servos.  When the wings came off the servo connector body stayed in the fuse and the servos wires and pins went with the wings.  
              My question is : can I simply re-insert the servo pins in another connector body (taken from defuct servos or extentions) ?
          Thanks,
          Paul
