hmm, I was just going to put a "suitable" resistor in though a regulator is a better option, a sot-223 lm-317 is $1.50, plus 2 resistors,perhaps a cap and a 20ma 805 package LED which would be pretty damn bright, particularly in green.
Probably add $5 to the rrp, other big issue is at 26V (6s) its going to get ~30C hotter than ambient (ie 30C day it'll be 60C). Its got about half a watt to dissipate.
Hmm, Powering it from the BEC is easy, but is it good enough for a power light? A futzed up BEC = wonky reading. _________________ Mechanical engineers build weapons, civil engineers build targets
