Short radio range (Ve-
hicle stops responding
to transmitter at short
distances)
Damaged or improperly installed re-
ceiver and antenna
Check receiver antenna for damage. Ensure antenna is
properly installed in tube and mount, extending perpendicular
from the ground. Ensure all connections are secure
Receiver is malfunctioning Replace receiver
Battery voltage too low Replace or recharge batteries in transmitter and vehicle
Steering not responding
as expected
Trim not set properly Adjust steering trim
Screws too tight on steering parts Adjust screws to allow for free motion
Fasteners have become loose
Check and tighten all fasteners to as new condition, be care-
ful to not over tighten
Vehicle not responding as
expected to transmitter
Trims not set properly Adjust throttle and/or steering trim
Radio system lost bind Re-bind radio system
Bad electrical connections
Check motor and battery plugs to ensure they are fully con-
nected
Wheels twitch while
vehicle is idle (controls at
neutral)
Transmitter too close to receiver (<1m) Increase distance between the units
Receiver wire damaged Inspect antenna for damage and replace if necessary
Receiver antenna not installed in vertical
position
Install in mount with care to not damage antenna wire
