This is the stuff I use that is really good, it has zero-no stretch and just works awesome. You do not even crimp it just twist it and heat the wire up and the nylon bonds its self together.
34235T23 Thats the stuff I run right there its 120lb test. Just copy that into the mcmaster site and it will come up its a 7x7 strand low stretch.

Ben's words of wisdom when it comes to servo setup:
1.Servos break, they're servos, so yes someone could have a bad servo. Take your linkages off and move the servos and try to resist them with your hands. A weak one is pretty obvious.
2.Make sure your surfaces move smoothly. This really means "If you are having problems with your rudder, fix your tailwheel, it's causing drag and overworking your servo".
3.Make sure your servo arm is not too long. Most arms have several holes for exactly this reason, and drill bits work every time they are tried. You want 30 degrees on ailerons, 45 degrees on elevator (rudder is not as critical, 40 degrees or anything close) while you have MAXIMUM endpoint on the Tx on that channel.
We fix dozens of setups at fly-ins every year. The above suggestions take care of the servos. Just for thoroughness, here's the other things we fix:
4.Put 75% expo (in the correct direction! Negative on Hitec and Futaba, positive on JR and spektrum) on all surfaces.
5.Make sure the elevator servo doesn't have sloppy gears.
6.Make sure it's not a HobbyKing prop.
7.Take off, trim the elevator and rudder for it to fly straight.
8.Roll it inverted, if it climbs or dives move the battery to compensate.
If you look at the specs on any servo, youhave the torque in oz/in, but most installation are compromised, resulting in this torque being reduced. You can really easily tell how bad a particular install is killing torque by looking at the endpoint adjustment on the Tx.
To be "Right", the endpoint should be maxed out. On my Tx, that's 140% on the ATV (servo travel or endpoint) adjustment.
If my servo arm is too long, I can't use the full 140%, I have to turn it down. Every bit it is turned down is reducing the effective torque of the servo. On my setup, on 4S, I can be compromised down to about 115-120% before I start noticing. At 100%, I can definitely feel it.

Move throttle stick to WOT
Turn on power to ESC
Adjust WOT EPA up until ESC beeps recognizing full throttle then go about 3% more
move throttle stick to idle it will beep again
adjust idle EPA up until ESC beeps recognizing idle stick position then go about 3% more
Then you leave your EPA alone. If you want to adjust anything after that to change the "feel" of the throttle curve you need to use something other than the end points

thank you cmala for the perfect explanation of how to do the fixed endpoint adjustment!

I pledge allegiance to the planes
of 3DHS, Scott Stoops and Andrew Jesky fame.
And to the flightline for where we stand
with our transmitter in our hand.
One group, under Ben, with batteries and stick time for all.

So finally got some pics of some new vinyl I had designed by Mr. Nick Frederick of nachoscheese.net
awesome stuff, couldnt have asked for much better. Feel free to contact him if you want a set for your own osiris (just tell him you want my osiris package...i think its the only one he has made so far)
enjoy!
