Caution for LiPo battery
The ESC features a low voltage cut-off at 3.2V per cell. When driving your boat, as soon as you notice the the boat slows down, which indicates that the ESC low voltage cut-off has been initiated. You should immediately drive the boat back to shore slowly. Recharge the battery and race again. Don’t keep racing the boat when the ESC low voltage cut-off initiates, otherwise, you will allow battery over-discharge, causing damage to the battery pack.

Circuit & Cooling System Diagram

Preparing Your Boat For Operation
Assembling the boat stand Insert three ABS pipes into the holes of two boat stands shown in photos, compress the boat stands and ABS pipes tightly, then stick EVA to the four corners, this will protect the hull bottom from scratches during construction and storage.

Installing the rudder and propeller

1. Take out the aluminium rudder from the parts bag.
2. Loosen the grub screw located inside the upper trailing edge of the rudder and slide out the mounting pin through the top.
3. Slide the steering pushrod through the clevis on the rudder (first loosen the clevis grub screw if necessary), then align the rudder into the rudder mount on the hull, reinsert the mounting pin then tighten the grub screw securely.
4. Lastly, tighten the grub screw on the pushrod clevis securely.
5. Loosen the nut on the propeller shaft with a 7mm wrench, install the propeller, reinstall the nut and tighten it securely.

Warning: Never attempt to work on the model while the propeller is installed and the model is powered on, the propeller can cause severe injuries when spinning.
Tip: Once you’ve finished the rudder assembly, power on the model (without the propeller installed), centre the steering servo (servo arm at 90 degrees), then re-align the steering pushrod by loosening the clevis grub screw, centring the rudder, then retighten the grub screw securely. Never attempt to make adjustments while the model is powered on with the propeller installed!

Recovery fin
The Aquaholic V3 includes a transparent plastic recovery fin that bolts to the top of the rudder. This fin provides steering control should your boat capsize while running in rough conditions. Please see the photo for the installation position with the included M3 fixing bolts/nuts (2pcs each).

Installing transmitter batteries (RTR version only)
NOTE: The transmitter is not water resistant and should never come in contact with water.

1. Install four fresh “AA” batteries. Follow the diagram located at the bottom of the battery tray for proper battery orientation.
2. Turn the transmitter “ON”.

Receiver connection diagram
Caution: Before racing the boat, Please use the balloon supplied in the tool bag to wrap the receiver for waterproofing.

Installing the Battery

1. Rotate the plastic lock on the hatch 90 degrees either to the left or right.
2. Lift and remove the hatch.
3. Attach battery connector.

NOTE: We recommend you 2 packs of 7.4V 4000mAh+ 35C+ Lipo battery for maximum performance. Use the provided battery straps which are already installed on the battery locators inside the hull to secure the battery. The battery locators help align the batteries for the best running centre of gravity for maximum performance. Below are the battery’s locations inside the hull.

NOTE: There is a waterproof rubber ring glued along the slot of the hull, always make sure it’s securely positioned before re-installing the upper deck.

TRANSMITTER/RECEIVER BINDING

The binding process effectively ties the transmitter and receiver together. Under normal circumstances, both items are supplied like this from the factory. If, however, you find that your transmitter and receiver are not bound (the receiver’s red LED is flashing), you should do the following:

1. Insert the BIND plug into the “BIND/VCC” port of the receiver.
2. Power “ON” the receiver by connecting the battery to the ESC. The receiver’s red LED should now be flashing quickly.
3. Hold down the “BIND” button on the transmitter, then switch the transmitter’s power switch “ON”.
4. The green LED on the transmitter will flash quickly indicating that it is in “BIND” mode. At this time, the receiver’s RED LED should change to slow flashing, indicating that the transmitter and receiver are now bound.
5. Remove the BIND plug from the receiver’s BIND/VCC port, then disconnect the battery.
6. Power cycle the transmitter and then reconnect the battery to the ESC. The receiver’s RED LED should now be solid-lit. The binding process is now complete and the receiver is ready to receive commands from the transmitter.
   Note 1: During the binding process, the transmitter and receiver should be around one meter apart and no other similar devices should be within 10 meters.
   Note 2: If the receiver’s RED LED is flashing, this indicates a binding failure, please do again as above indication.

Checking the radio system

1. Always turn the power “ON” to the transmitter before connecting the batteries with the ESC.
2. Plug the battery into the ESC plugs and listen for three continuous >Beep<>Beep<>Beep<. (Signal noise of auto-detected ESC)
3. The ESC & motor is now armed and ready for operation.
4. Check the direction of the rudder, the trailing edge of the rudder should turn right when the right input is given. Conversely, when left input is given, the trailing edge of the rudder should turn left.

Transmitter introduction

EPA Adjustment
Function
Use this when performing left and right steering angle adjustments. End Point Adjustment (EPA) adjusting value range: 0%-100%

Setting

1. Steering (right side) angle adjustment Rotate the “ST/R” knob to the left endpoint means a minimum value of 0%, right endpoint means a maximum value of 100%.
2. Steering (left side) angle adjustment Rotate the “ST/L” knob to the left endpoint means a minimum value of 0%, right endpoint means a maximum value of 100%.

CAUTION
When adjusting this function, make sure the direction is in agreement with the boat direction, you can adjust by the STEERING “REV-NOR” switch.

Trim Adjustment
Adjust “ST/TRIM” and “R/L” so that the rudder is centred before the operation, you may also adjust this control to make the boat run straight during operation.

CAUTION
When adjusting the steering trim, make sure the direction agrees with the boat’s direction, you can adjust by the STEERING “REV-NOR” switch.

Throttle trim
Adjust “TH/TRIM” and “B/F” to stop the propeller from turning while the throttle trigger is in the neutral position.

Speed Control Specification
The H-King Marine brushless motorboat is assembled with 60A water-cooled brushless ESC, please see below the specifications:

• Protections: Thermal protection activated at 120°C. LVP (low voltage protection) is engaged when
• LiPo battery (per cell) drops down to 3.2 Voltage.
• Operating Cells: 2S-4S LiPo
• Current Rating: 60A
• Peak Current: 70A within 10 seconds
• BEC Output: 2A/5V

Calibration

1.  Set the trigger to maximum throttle then turn on the transmitter.
2. Connect the motor and receiver to the ESC.
3. Plug the battery to power on the ESC.
4. After 4 high-pitched tones, set the trigger to minimum throttle.
5. After 3 repeat monotones, cut off the power of ESC.

Lubricating The Drive Shaft
Lubricating the flex shaft is vital to the life of the drivetrain. The lubricant also acts as a water seal, keeping water from entering the hull through the stuffing box. Lubricate the flex shaft, propeller shaft and all moving parts after every 2-3 hours of operation.

1. Use the 2mm allen key to loosen the two grub screws of the coupler which connects the flex shaft, then slide the flex shaft w/ prop shaft out of the stuffing tube.
2. Lubricate the flex shaft w/ prop shaft with the Waterproof marine grease, reinstall the flex shaft w/ prop shaft in reverse order, be sure to retighten the two grub screws of the coupler.
   NOTE: Running the model boat in salt water could cause some parts to corrode. If you run the boat in salt water, rinse it thoroughly in fresh water after each use and lubricate the drive system.
