I agree ... Compuserve, That's Funny!

What I don't get is why guys want to use Regulators with A123 batteries. A123's are rated at 30 C. You take two packs in parallel, that's 4600mah at 30 C which equates to 130 Amps! Continuous! I can't imagine any regulator made that could compete with that. And the Servos and RX just seem to thrive on the 6.3 volts.

Lipos, well thats a different story. You need to reduce the voltage as the 7.4V is a little too high for most servos.

The weak link in the current carrying chain is the motor controller inside the servo. Or the motor itself. When I've had electrical meltdown it's always been a cooked motor controller or motor inside the servo. Never in the wire or servo plug. It fries and then usually (hopefully) blows an open circuit so the wires don't start melting. I've not had it ever happen from aerodynamic forces. It's only been from mechanical binding or crash damage to the servo or linkage.

Just my two cents trying to save guys money and complexity. And I'm not knocking any setup that a modeler likes or has had great success with. There are a lot of great ways to get to the desired result of a dependable, redundant system.


Happy Flying,
