helirulz, While your theory is correct for a straight wire the difference is at ANY point in a wire you add a resister as in "small guage wire" (connector) you'll have the same POTENTIAL to the Source and Load as a total resistance.

Matt was just relating that you can add larger wire but overall it does NO good.

The connector is the weak link in a wire harness as they cannot be inlarged to match a wire enlargment.

That's where the CCPM version shines. One connector per servo instead on only one connector to power everything. Also you will have multiple power wires going to the receiver carrying power for redundancy instead of just one if its done correctly.

correct, the ccpm regulator feeds the rx 5v via 3 leads, then each of the cyclic servos have their own power lead as well... then new static voltage regulators (non-adjustable) will have 2 rx outputs and a 5v regulator for the gyro/tail combination and also have all leads coming from the same side of the board, but those are about 3 weeks out. they will be available in 5.5v, 6v and 6.2v versions and also include the onboard power led and switch like the other regulators

While yes, you get lower voltage drop with larger gauge wire, look at the numbers.

16 ga wire has a resistance of 4.08 ohms, per 1000 FEET. 22 amp rated
18 ga - 6.52 ohms per 1000 feet. 16 amp rated
20 ga - 10.36 ohms per 1000 feet. 11 amp rated
22 ga - 16.14 ohms per 1000 feet. 7 amp rated
24 ga - 25.67 ohms per 1000 feet. 3.5 amp rated.

So for a one foot wire the resistance is

16 ga - 0.00408 ohms
18 ga - 0.00652 ohms
20 ga - 0.01036 ohms.

At 3 amps current (max the connector is rated for) this results in the following voltage drops (6 volts, 1 foot of wire):

16 ga - 0.0123 volts
18 ga - 0.0195 volts
20 ga - 0.0312 volts
22 ga - 0.1 volts
24 ga - 0.158 volts

Hardly enough to matter.

Using a huge wire will not reduce the resistance of the weakest link.
