Driving Your STRX-9 Cont.
If the boat does not run in a straight line
when not being steered, you can fix this by
adjusting the steering trim located on the
upper right hand side of the transmitter.
1. Run your model on calm water when
adjusting the steering. If your model runs
to the right when not being steered, press
the “ST. TRIM-L” button. Re-center the
model and see if this has corrected the
problem. Keep making small adjustments
in this way until the model runs straight.
2. Press the “ST. TRIM-R” button to correct if
the model steers to the left without being steered in the same way as explained above.
Lubricating the Drive Shaft
Troubleshooting
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 tube. It is
recommended to lubricate the flex shaft, propeller shaft after
every 2 or 3 runs.
1. Use one hand to hold the silicone coupler tight, while the
other hand pulls the propeller shaft out from the stuffing
tube.
2. Lubricate the flex shaft/prop shaft with the waterproof
marine grease, reinstall the flex shaft/prop shaft in reverse
order. Be sure to push the flex shaft end into the silicone
coupler for full connection.
NOTE: After several times of pulling the flex shaft out from the silicone coupler, the silicone
coupler might lose flexibility, which is not good for the connection of the flex shaft.
Once this happens, replace the silicone coupler with the extra coupler that was
included in the gift box.
