The align DS650 or DS620 are standard size tail servos and rated at 6v. I have a 650 on my 700 at 6v and its fantastic.

1) It's not a resistor, it's a diode, which drops the voltage by about 0.8V. The diode itself is pretty resilient. Your weak point would be the servo connector, so I just use heat shrink to ensure the connectors will never come apart. This is pretty common and I've never seen this solution fail.


The part itself only costs a few cents from an electronics supplier.

2) There are also regulators available, but that's a fair bit more pricey and heavier:


3) The other option is a receiver that has a built-in low voltage output channel for the gyro/rudder channel.


When all you've got is a hammer, every problem starts looking like nail!
