Steering Trim: The model should go straight without turning the steering
wheel. If not, tap the trim lever found just above and to the right of the
steering wheel in the direction needed for the model to go straight. Each
tap of the trim button will be accompanied by an audible tone indicating
a change has been made. It may take several taps to get the correct trim
setting.
Throttle Trim: The model should idle without the tires rotating when the
trigger is at its neutral position. If not, tap the trim lever found just above
and to the left of the steering wheel to reposition the throttle servo and
close the carburetor and apply more brakes. Note that additional braking
force is applied when you push the trigger forward.
Synchronizing the Steering Servos: If you remove the steering servos or
the servo savers you will probably have to make some small adjustments to ensure they are working together at
maxium capacity. With the servo savers removed and the linkaged attached,
• Turn on the radio and reset the steering trim to read “0” (which is neutral) on the radio screen.
• Loosen the setscrews securing the linkage slightly and mount the servo savers so they are timed as close as
possible like that seen in the photo.
• Use the steering trim on the transmitter to fine-tune the timing of the servo savers.
• Make sure the front tires are pointing forward and lock the steering linkage in place by tightening
the setscrews.
Telemetry Sensors
• The battery power of the receiver pack will automatically register on the
readout screen.
• The engine temperature requires that the temperature sensor (SPM1450) be
installed around the head just above the head bolts as seen in the photo. Note:
The temperature sensor must be removed before removing the head from the
engine. There is an external plug near the radio box which will allow you to
disconnect it if you wish to remove the engine for cleaning.
• The RPM/Speed sensor (SPM1452) mounts directly
below the front of the radio box. It must be kept clean
to operate correctly. There is a silver stripe on the drive
coupler (just below the sensor) that must also be kept
clean. Use only a soft brush to clean these – Do Not
Use Any Solvents at any time on these items. If the
silver stripe gets removed use one from the (SPM1512)
Telemetry RPM sticker sheet.
Maintenance
In addition to the service needs pointed out in this guide,
you should try to maintain your new LST XXL for proper performance and to prevent wear. If dirt gets in the
moving parts it can seriously hinder the performance of the model. Use compressed air, a soft paintbrush and/
or toothbrush to remove dirt and dust. Avoid using solvents, if possible, as this can acutally wash the dirt into
bearings and areas not accessible without disassembly, causing additional wear. We suggest you follow these
basic guidelines.
• Remove as much freestanding dirt and dust as noted above.
• Never leave fuel in the tank for more than a couple of hours.
• When done running for the day or longer, let the engine run out of fuel. Remove the air cleaner and pour a
little WD40 or quality after-run engine oil into the carburetor and spin the engine over a few seconds.
• If needed, clean and re-oil the air cleaner before installing it back on the model.
• Inspect the chassis for worn, broken, or binding parts and repair as necessary.
