ok here is the step down regulator instructions;
the Align 2 in 1 provides 5.8V which is a little bit to high for most rudder servos. Need to knock off 0.7V.
You can do this by taking a short servo extension wire.
Cut the red wire.
Solder a Diode 1N4001 in between the 2 ends (kathode to the servo side)-kathode is end with strip around end.
and your done.... Use this between your gyro and rudder servo.
you can find this diode at radio shack.
so all you need is diode 1n4001 and servo extension,each diode reduces voltage by 0.7v.
