Revo • 33
Introduction
Your TRX 2.5R Racing Engine is broken in, the fuel mixture is balanced,
and the idle is set…now it’s time to have some fun! This section contains
instructions on forward/reverse shifting, and making adjustments to
your Revo. Before you go on, here are some important precautions to
keep in mind.
Don’t run your Revo in water, mud, snow, or wet grass.
It’s
tempting, but water and mud are easily drawn through the air filter
and will severely damage the engine. Small amounts of moisture can
cause electronics to fail and loss of control over your Revo.
The TRX 2.5R Racing Engine is extremely powerful. Remember to
apply the throttle gradually to prevent wheelies or loss of control.
Don’t hold Revo off the ground and rev the engine excessively with
no load on the engine. This practice could result in internal engine
damage. Avoid over revving the engine when Revo is airborne after
a jump.
Avoid excessive high-speed running for extended periods of time or
over long distances. This could cause the engine to build up enough
speed to exceed maximum safe RPM limits.
Don’t drive your Revo with drive train damage of any kind. The
engine could be damaged due to overloads caused by drivetrain
friction, or over-revving caused by loose or missing parts.
Don’t tow anything with your Revo. The engine is cooled by airflow
created by speed. Towing creates a high load on the engine, and at
the same time limits cooling of the engine due to low vehicle speed.
If your Revo gets stuck, stop driving immediately. Move the vehicle
and then continue driving.
Never turn off the radio system while the engine is running. The truck
could run out of control.
Forward and Reverse Operation
Forward and reverse gears are
selected with the shift button
located in the transmitter handle
grip. The switch is normally in the
down, or forward, position.
To shift into reverse, bring your
Revo to a
complete stop
and
push the shift button up.
Accelerate to engage the gear.
To return to forward gear, repeat the same procedure and move the
shift button down.
Revo will not shift between forward and reverse unless the truck is
stopped. If it will not shift, then refer to the troubleshooting section
on www.Traxxas.com or call Traxxas support.
Driving Tips
Monster trucks by design have a high center of gravity that requires a
different driving technique. To prevent rollovers, slow down as you
approach turns and then apply moderate throttle through the turns.
This technique will help Revo grab the surface and turn sharper.
Do not apply brakes and turn the wheel at the same time. You could
tip the truck over.
When jumping, apply some throttle while Revo is in the air to keep
the truck’s nose up and land level on all 4 wheels. Be careful not to
over-rev the engine or land at full throttle. Either could seriously
damage your Revo. If the nose of the truck is too high, then quickly
tap the brake to level the truck in the air.
Drive over large obstacles (such as curbs and rocks) at an angle,
instead of head on. This will allow the suspension to articulate and
absorb the impact much easier.
Even though Revo is capable of high speed in reverse, it is very
difficult to control while driving in reverse. Limit your reverse speed
to prevent crashing or flipping your Revo.
Change or clean your air filter element after each hour of running.
This is critical for the life of your engine. Running time includes the
engine break-in period.
