Futaba S9252 Servos
This is the Futaba S9252 Digital High Torque, All-Purpose F3C Servo with High-Current Wire Lead and "J" Connector Pre-Installed.
This servo can produce high-current draw from your batteries If using NiMH or LiPo batteries, make sure they are capable of delivering sufficient amps.
FEATURES: Digitally enhanced microprocessors cut about half the response time from transmitter input to servo reaction.
Coreless motor Dual ball bearings on the output shaft Plastic/nylon gear train Moderately high speed High current, high capacity wire lead with low resistance Case is made of Black plastic Dust and water resistant (Not waterproof) Works well with all control surfaces on F3C helicopters or precision fixed wing aircraft.
One year warranty INCLUDES: One Digital All Purpose Servo w/Small Round Horn
Four Rectangular Grommets
Four Brass Bushings
Four Mounting Screws
One Large Round Horn
One Six Arm Horn
SPECS: Speed: 0.14 sec/60° @ 4.8V
Torque: 92 oz-in (6.6 kg-cm) @ 4.8V
Weight: 1.8oz (50g)
Power Supply: 4.8V (Futaba does not recommend using 6V)
Dimensions: 1.6 x 0.8 x 1.4" (40 x 20 x 37mm)
COMMENTS: S9252 Digital Servo Precautions:
-It is best to avoid long leads and Y-harnesses especially with standard grade wires. If problems are encountered, consider using heavy duty wire such as Futaba's Heavy Duty Series or Hobbico's Pro Series ,minimizing lead lengths, and/or removing Y-harnesses.
-Current Drain: Futaba S9252 Servo is specially designed for high- torque and high-speed, therefore very high current drain is normal at startup. For ultimate performance when using this servo, please review the following points.
(1) Always use a 4.8V NiCd battery. Dry cells are rated at 1.5V each making the overall voltage 6V which will damage the gyro.
(2) When using systems with the battery fail safe function it has a higher cut-off voltage setting which will cause shorter operation time.
(3) When installing the servo please check pushrod linkage to make sure there is no binding in order to prevent excessive power consumption and decrease the life of the motor and battery.
When Used With GY501 Gyro:
Switch the GY501 servo frame rate function (Frm) from "NOR" to "High" to display the performance of the gyro to the fullest. Setting Method:
(1) Press the GY501 FUNC+ or - key to call the Servo Frame Rate Setup Screen.
(2) Press the DATA+ or - key to display "High".
This digital servo cannot be used with the following * AM * transmitters as the servo neutral signal is: 1310us). CONQUEST AM, FG Series (T4FG, T5FGK,T6FG, T6FGK, T7FGK), New Terratop, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.

Essential Part It's used to control the piston or waterpump motor forward,reverse and stop. It has 2-stroke 3 switchs,Auto-stop in any position.Signal loss,main low voltage,override depth and leak failsafe was included.Float automaticlly.Voltage 6-12V,Current 20A.Suit for all kinds Arkmodel WTC,It's very necessary for RC submarine.

Optional PartPressure Switch, it helps submarine’s maximum depth is limited to approx. 2 meters (6 ft). If the submarine dives below this level, the BCU will automatically switch to the "surfacing mode" and empty the Tank. The model will then resurface unless the three-stage switch (stick) is back in neutral position. Otherwise, with the stick left at "filling mode" the model will emerge to a depth above 2 meters after which the tank will start filling again (and so on).In order to maintain the depth of sailing in about two meters.

Pressure Switch installation: Pressure switch can be mounted anywhere inside the hull(WTC), let silicone tube be leveled , and the tube is connected to the bow endcap’s nozzle, pay attention to water leak at the nozzle. The nozzle should be connect the outside and touch water, so the pressure switch can sense the depth of water pressure.For avoid additional errors pressure (such as head-flow pressure), single hull submarines(without WTC), please using an external elbow, avoid direct water pressure impact pipelines.For a double hull submarine(with WTC) because the enternal hull can block the water flow, the nozzle can be directly facing forward.

Optional Part Used to plug in the RC switch channel，to control the simply switch action,such as light,depth,but cannot used for high voltage motor.
