<DIV>I can't find by physical inspection any "wacked out servos" or other issues that might cause increased current load on the regulator. So....I'm trying to find the typical (or average) current that should be seen at any moment (instant) on a meter in-line with the regulator. Then I'll run my set-up and compare. If I'm in the ball park (less than 1A based on a couple of inputs so far) then the problem is not related to "wacked out" servos, binding etc.</DIV>

Average current is not the same as instantaneous current, unless the <U>only</U> current being drawn was just for that <U>single instant in time</U>. Anyway, I will repeat, with an added quailifer, for the sake of understanding for where to look to help you solve the problem:<BR> <BR>If you are using a JACCIO, Tech-Aero, or whatever regulator in a pattern setup, even with a YS CDI on a shared output, and if you find that you need a heat sink, then:<BR> <BR> <BR><U>Something Else Is Wrong</U>. Check your setup for binding linkages, stiff hinges, whacked out servos, whatever.<BR> <BR>Seriously, check your setup, OK? Just trying to help here.<BR><BR>Regards<BR>Ed<BR> <BR>

<DIV>Actually, if you consumed 200mAhr in 0.25hrs, then your average (instantaneous) current was 800mA.</DIV>
