If you really want to spend some money I highly recommend this wire. http://www.bulkwire.com/wire-cable/ptfe-high-temperature-stranded-wire.html
Its teflon and has a lot of strands inside and is very very strong (flew to 70 miles on a sounding rocket :) But its very expensive and a bit hard to strip :( Michael Stephens [email protected] On Wed, Mar 27, 2013 at 10:28 AM, w9ya <[email protected]> wrote: > Um....I use the following; > > 1 - Properly routed and supported *stranded* wiring. i.e. NO > unsupported flexing of the wiring loom. > > 2 - Tinned (with solder of course) wiring is specifically indicated. > It will not release from under the screw terminal when the terminal is > properly tightened and supported. > > 3 - Double check the connections before each flight; by making sure > the wiring and screw are snug AND that the wiring is still routed and > supporteed correctly. > > YMMV of course but I preclude intermittent continuity issues resulting > from the lack of a gas tight ferrule connection. > > Very best regards; > > - Bob Finch > > > > On Wed, Mar 27, 2013 at 8:16 AM, Thomas Müller > <[email protected]> wrote: > > If you like to attached stranded wire to screw terminals you should crimp > > the ends in a ferrule.
