The RHINO pro SHV digi 4 servo is a 29 mm digital servo designed for use in large-scale models. The new pro SHV servo is faster, more powerful, and more durable than the proven RHINO digi 4, of which thousands are now in use. More performance, with higher torque and faster transit speed, and more durable with a new triple-ballraced heavy-duty steel gear set. The operating voltage range has been expanded to 7.4 V, allowing the servo to be operated directly with up to two-cell LiPo batteries.

Large 1 : 5 scale model cars make very exacting demands on the servos, and for many years the RHINO servo has set the standard with its extremely robust, outsize metal gearbox and 8 mm output shaft for the output device. An integral aluminium heat-sink cools the motor and electronics very effectively. Servo case gaskets make the unit dust-proof and splash-proof. The enormous power and robust nature of this servo also make it an excellent choice for large models generally, such as F3A - XXL large-scale model aircraft, as well as for non-standard applications.

Adapter FG # 6118/02 is required for installation into a FG/Smartech car.

High-voltage (HV) servos
HV servos have a broad operating voltage range of 5 - 7.4 V, i.e. they can be operated directly with two-cell Lithium-based rechargeable batteries (e.g. LiPo, LiFe, LiIo). The outstanding features of LiXX batteries compared with NiXX types are their higher energy density and lower self-discharge rate, and for these reasons they are increasingly used as power supplies in model RC systems.

The higher voltage of LiXX batteries means that the current drawn by an HV servo is lower for a given output power than that of conventional servos, which are generally designed for a nominal voltage of 4.8 - 6 V. When used with 2S LiXX batteries, these older servos must therefore be operated with a separate voltage reducer. This reduces the overall efficiency of the system, leads to unnecessary dissipated power, requires additional electronic complexity and more connectors ( higher costs, greater failure risk, higher weight).

Modern receivers (e.g. M-LINK) are designed for voltages up to 9 V, i.e. with HV there is no longer any reason not to use the modern, superior LiXX battery technology.

The following servo parameters can be adjusted using the MULTImate test and programming unit # 8 2094:
  • Direction of servo rotation
  • Servo transit speed
  • Servo travel, left / right (max. 2 x 90°)
  • Servo centre
  • Servo deadband
  • Fail-safe (On with servo Fail-Safe position / Off)
  • Reset to factory default settings

Safety Notes

Application
Designed exclusively for use in modeling. It is prohibited to use the unit for other purposes, such as personal transport vehicles or industrial installations.

Regular checking
Check your servos regularly for lost motion, changes to the running sounds, power and transit speed. Note: when the servo is under load you will hear humming and whistling sounds. This is typical of all digital servos, and does not indicate a defect in the servo.

Do not overload the servo
Digital servos excel in their precision of movement and great holding power. In contrast to conventional servos with analogue electronics, commands are constantly passed to the motor of a digital servo. The servo attempts to move to the commanded position and maintain it under all circumstances. Where loads are servere, this results in very high current drain, and in the long-term this can result in overloading and even servo failure. For this reason the following points must be observed when using digital servos, to minimize the risk of failure and to ensure that the servo´s effective life is as long as possible.

Make full use of maximum servo travels
If the travel of a control surface is excessive, do not correct it by reducing servo travel at the transmitter, but by re-connecting the linkage inward on the servo output arm (or outward at the horn). This exploits servo torque more effectively, and at the same time reduces the power required of the servo, and therefore its current drain.

Ensure that the control linkage is free-moving
From time to time disconnect the linkage from the servo and check by hand that the system still moves easily and smoothly. This reduces current drain considerably, and also helps to ensure accurate positioning.

Digital servos must never be stalled for a long period
This is very important at the servo´s maximum travel (e.g control surface at one end-point, model car brake / steering system)

Avoid any situation in which the servo is constantly working against a force

E.g. carburetor with spring-loaded throttle arm.

Protect the servo from vibration
If the servos are subject to vibration in the model (e.g. glow motor), it is essential to provide adequate vibration damping. This can be achieved by using the rubber grommets supplied when installing the servos.


Using the servo for the first time

Connecting the servos to the receiver
Multiplex divi 4 HV-servos are available with the universal UNI connector (UNI), which is used by many RC equipment manufactures. Before connecting the servo check that the pin assignment is correct for your system.

Power Supply
The operating voltage range of Multiplex divi 4 HV-Servos is 4.8 - 8,4 V (4-5 NiCd or NiMH respectively 2S-LiPo-cells). All digital servos consume more current under load than conventional analogue servos due to their higher-rate signal frequency and correspondingly increased power and accuracy. This must be borne in mind when considering the power supply, especially if using a BEC power supply with an electric flight speed controller or car speed control.

Important:
Be sure to use a NiCd, NiMH battery of adequate capacity. Use cable of generous cross-sectional area, and only use high-quality connectors. Voltage collapse in the power supply, for whatever reason, can cause interference to the RC system.
