to run nitro vehicles ar more popular now than ever,
but many RTR owners don't know much about the internal
workings of their vehicles because they didn't build
them. Eventhough the vehicles come RTR doesn't mean
that they will never require maintence.
Quick visual check. Look closely
at all moving parts and for obvious problems.
Check all major fasteners. Make sure all
the screws that hold the bulkheads, drive train
and engine on the chassis are not loose. Do a full
vehicle check at least once a month and a visual
check before each run.
Wiggle all the suspension and steering parts.
Be sure that all the components are firmly attached
and be sure that the parts only move in the direction
they were intended to move.
Spin the drive train. Any degree
of drive train binding or poor brake adjustment
can lead to excessive engine temperature and poor
all around performance. Hold the vehicle off the
ground and spin the wheels. There shouldn't be any
resistance or tight spots. If their is a problem
and it is not fixed it could lead to engine overheating
or clutch damage. Some points to check are spur
gear mesh, faulty clutch, bad bearing, or a brake
assembly that binds.
Check your transmitter and transmitter batteries.
This is the most common cause of really expensive
crashes. Most radios have some type of battery meter
but most RTR's don't have this system for the receiver
batteries. Don't rely on average alkaline AA batteries
for more than two hours of run time. Monster trucks
use even more battery power because the servos have
to strain more to turn the oversize tires.
Inspect the fuel and exhaust systems.
Make sure that fuel lines are connected in the right
places, and check them for cracks and slits. These
small problems will lead to endless tuning problems.
Make sure that the fuel tank filler cap is seated
properly to ensure proper pressure is kept in the
