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

Sat Mar 18 06:48:10 AKST 2006

Full size aircraft don't use soldering I believe. I know we don't at
Bombardier. It has something to do with vibration.

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.

Ed,
    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

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 sliver 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
