i have the 2 in 1 but am not running a setdown to the tail. is the 5.7 too high for the gyro or when everything is running will it be less and ok? i have the spectrum VR regulator i can throw on if needed. thanks

If your using a fast dedicated tail servo you need a step down or you'll burn the servo out. The gyro will be fine on 5.7v. Put a step down between the gyro and tail servo.

If there's more than one three wire connection from your gyro to the servo, the step down works best between the gyro and the servo.

the spectrum regualtor i have has 2 outputs. heres the listing i found for it. it says it works best for between gyro and reciever just like i wanted it. heres the decription

-----------------------------------------------------------------
Key Features:
- 2 inputs provides the ability to run applications at lower voltages
- 2 outputs distributes the load over two connectors to minimize drops in high current draw applications
- Voltage input: 5.5 to 10 Volts
- Continuous current: 2 Amps (3 Amps Peak)

Overview:
The VR5203 provides regulated voltage protection for up to two servo functions with two input ports and two output ports. This unique component eliminates the danger of higher voltage power systems to standard voltage servos by being placed in between the receiver and the servo needing regulation. This allows the rest of the system to work at a desired voltage.

Applications:
Spektrum’s Dual Output Step Down Regulator is primarily designed for use with gyros in helicopters. Most brands of gyros/ tail rotor servos have voltage limits of 6 volts or less. The Dual Output Regulator installs between the receiver and the gyro in the rudder and gain channels and regulates the voltage to the gyro and tail rotor servo to a constant 5.2 volts. This allows the rest of the system to operate using higher voltage, typically 5-cell NiMH 6 volts or even 2-cell LiPo 7.4 volts, providing increased servo performance and response.

Additional Applications:
We’ve also discovered that there are many other devices that are typically used in models which have voltage limits that the Dual Output Regulator is ideal for. Some brands of retract servos (including the JR791) have a limited voltage range and installing the Dual Output Regulator inline between the servo and the receiver allows the retract servo to function properly.

Important:
The Dual Voltage Regulator is limited to 2 amps of continuous current. It is designed to install between the receiver and the gyro, operating the gyro and tail rotor servo only (or other control devices like a retract servo, electronic switch, etc.).
It is not intended to be installed between the battery and the receiver to power the entire system.

SPECIFICATIONS:
Type: Dual input/ dual output step down linear voltage regulator
Voltage Input: 5.5 to 10 volts (4- to 8-cell NiCd/NiMH or 2-cell LiPo)
Output Voltage: 5.2 volts
Continuous current: 2.0 amps (3-amp peak)
Dimensions WxLxH: 23 x 32 x 12 mm .85 x 1.30 x .50 in
Weight: 7 grams/ .3 oz
