Hi Dean,

In my DA100 powered Extra, I put a 6 volt, 1.5 amp regulator at each servo and ran the 8.4 volts all over the plane, so I wouldn't need to worry about voltage drop in the long cables. An added benefit is that a shorted/stalled servo causes the respective regulator to shut down and draw very little current. The remaining servos don't see any degradation even with a dead short. Also each servo is isolated from the 8.4 volt bus so no voltage ripple is seen when the other servos are drawing current.

This is probably overkill for a pattern plane but I believe something everyone should consider in IMAC type planes.
