‘92H’ Series RTR Brushless EP Racing Boat
Lubricating the ‘92H’ series model’s flexible propeller shaft is vital
to its smooth operation and lifespan. The lubricant also acts as
a water seal, helping to prevent water from entering the hull via
the propeller tube.
It is recommended that you lubricate the propeller shaft and
tube every 2
~
3 hours of operation.
1) Use the 3mm Allen key provided and spanner to remove the
screws and nuts that secure the propeller shaft support.
2) Next, remove the propeller nut, propeller and nylon washer.
The propeller shaft support and flexible shaft shroud can
now be pulled off the end of the flexible shaft.
3) Lubricate the flexible shaft and shroud with waterproof
marine grease and re-install. Re-installation is the reverse of
the disassembly procedure.
Note: Never apply grease to the ‘92H’ series model’s brushless
motor.
(Model should be placed on its supplied boat stand with the transmitter switched ‘ON’, having previously read and
understood the separately supplied radio control instructions)
1) Remove the ‘92H’ series model’s upper deck by unscrewing the knurled knob at its rear section.
2) Insert battery packs into the hull as shown below and secure with the hook and loop strap inside the hull.
3) Attach the battery pack’s connectors to the matching connectors in the model. Do not force them together -
they only attach one way!
4) Re-position the upper deck, securing with the knurled knob. Finally, seal the upper deck with the waterproof tape
provided.
Attention: Before replacing the ‘92H’ series model’s upper deck, check to ensure that the water-cooling tubing that
connects to the motor is not obstructed or kinked, as this can cause the motor and speed controller to overheat and
potentially burn out.
Note 1: ‘92H’ Series models will typically run for around 7
~
8 minutes on fully charged Li-Po battery backs, although
this will vary depending on the type and capacity of Li-Po packs you choose. As soon as you notce a drop off in
speed you should bring the model back to shore or control may be lost.
Note 2: If you want to run your ‘92H’ series model for extended periods, you can purchase additional Li-Po battery
packs. However, continuous running of the model will generate high heat levels which will lead to premature wear of
the brushless motor. Once your Li-Po battery packs are exhausted, we recommend that you let the model cool down
for 5
~
10 minutes before installing fresh ones.
