Using the R.O.S.S. Starting System
The Ten-T uses the exciting new Remote On-board Starting
System (R.O.S.S.). It is absolutely critical that you read and follow
these instructions for proper operation and to get the full
enjoyment of this exclusive feature.
NOTE: When the engine is new it is harder for the
starter motor to turn the engine over, so it is very
important to understand and follow these steps.
COLD STARTS
1. You must read the “Tuning a Nitro Engine” section before
starting.
2. Make sure the LiPo battery in the truck has been charged.
3. Check to make sure that the exhaust exit tube is not hot.
4. Fill the fuel tank with fuel.
5. Switch on the transmitter and then the model.
6. Place the model on the ground in an open area. Push and
hold the starter button on the back of the transmitter
which will engage the starter and start turning the engine
over. It will take 4 or 5 seconds for it to draw fuel from the
tank as the engine turns over at which point you will hear
it starting to fire.
7. As the engine starts to fire keep the starter button
depressed and pull back the throttle ¼ inch. If the engine
starts running, the model will start to move. Give the
model at least half throttle and allow it to pick up some
speed before releasing the starter button. Note: If you are
running above 1500-feet elevation you will need to lean
both the high-speed and low-speed needles at least one
hour – more if at a higher elevations. Please read “Tuning a
Nitro Engine” again to understand proper tuning.
8. If the engine stops firing: close the throttle and continue
turning it over which should make it start firing again. Wait
a second and repeat step 8.
9. If the engine starts running: remove your foot and give the
model more throttle as it drives away. After it has gone 10
feet release the starter button and have fun.
10. All this should take place in about 10 seconds. Do not run
the starter for longer than 10 seconds at a time without
letting it cool.
HOT STARTS & RESTARTING
• If the model has run out of fuel prior to restarting, make
sure the exhaust pipe has cooled before attempting to
restart and follow steps #4 through #10 above.
• If the engine was stopped while there was still fuel in the
system, set the model on the ground and follow steps #8
through #10 above.
TROUBLESHOOTING
If the engine does not start to fire following the above steps:
1. Check for fuel in the tank.
2. Check the glow plug – see “About Glow Plugs” section.
If the starter stops abruptly:
1. The engine may be stuck at top dead center – especially if
new. Using a screwdriver place the tip so that it is between
the ridges in the flywheel with the shaft up against the
edge of the cutout toward the center of the chassis. As you
push down on the screwdriver handle the flywheel on the
engine will rotate toward the outer side of the cutout. Use
this method to rotate the flywheel no more than ¼ turn.
Use screwdriver to rotate flywheel
1/4-turn in this direction
2. Turn the receiver switch in the model “Off” then “On” again
which will reset the circuit breaker in the battery pack.
Press the starter button following steps #8 through #11
above. Note: This situation will stop after the first hour of
engine operation.
3. The engine may be flooded (too much fuel inside the
engine). Remove the head protector from the head and
blue igniter lead from the tip of the glow plug then the
glow plug itself. Turn the radio switch in the model “Off”
then “On” again which will reset the circuit breaker in the
battery pack. Place a rag over the top of the engine and
engage the starter for 5 seconds. Raw fuel should spray
out of the glow plug hole. Replace the glow plug making
sure to include the copper gasket on the plug. Reattach
the igniter lead and head protector and follow steps #8
through #11 under “Cold Starts.”
