Hello all, Here is the latest update to my ongoing measurement of various servo wires. The important lesson that I have learned is that it is always better to check the wire yourself than to believe what the manufacturers' claim.
Jimmy ---------------------------------------------------------------------------- This is a comparison of various servo wires. The following procedure was used. The diameter of an individual strand in a conductor was measured using a Mitutoyo Digital caliper. The number of strands in that conductor were then counted with the aid of a magnifying lens. This comparison uses the European system for wire sizes, where the equivalent area of a conductor is the total cross-sectional area of all strands in the conductor. For example, the equivalent CS area of a wire with 65 strands of .07mm dia each is calculated as follows: sq(.07/2)*pi*65=0.25 sq mm. The AWG (American Wire Gage) was not used because it is not straightforward for stranded wires. Explanations of AWG can be found on the Internet - here is one of them: http://www.fiskalloy.com/c-fact-pages/c-sizenomen.html Sample 1 Source: Included with an ASW-27 from HKM Modellbau Conductor colors, in order = black, red, yellow CS of one stand, in mm = 0.07 Total number of strands = 65 Equivalent area of conductor, sq mm = 0.25 Sample 2 Source: Local Hobby shop, from a spool labelled "Mulitiplex" and ".25 sq mm" Conductor colors, in order = red, black, yellow CS of one stand, in mm = 0.04 Total number of strands = 128 Equivalent area of conductor, sq mm = 0.161 Sample 3 Source: Hitec servo wire, 50ft, pn RCD57417 Conductor colors, in order = black, red, yellow CS of one stand, in mm = 0.08 Total number of strands = 28 Equivalent area of conductor, sq mm = 0.141 Sample 4 Source: Cermark servo wire, pn CM3713 Conductor colors, in order = black, red, white CS of one stand, in mm = 0.07 Total number of strands = 60 Equivalent area of conductor, sq mm = 0.231 Sample 5 Source: Local hobby shop, Robbe Futaba (rx battery wire with connector) Conductor colors, in order = black, red CS of one strand, in mm = 0.07 Total number of strands = 60 Equivalent area of conductor, sq mm = 0.231 Sample 6 Source: Electrodynamics Futaba J Heavy wire male pigtail, pn EDC1300 Conductor colors, in order = black, red, white CS of one stand, in mm = 0.07 Total number of strands = 60 Equivalent area of conductor, sq mm = 0.231 RCSE-List facilities provided by Model Airplane News.
