TM Safety Precautions Batteries and Charging: The Desert Truck uses rechargeable batteries such as NiMH. These batteries all have special requirements to preserve performance and last a long time. Read all instructions and precautions that are provided with the batteries intended to be used in the Desert Truck. • Read all instructions provided by the manufacturer of the batteries. • Responsible adult supervision is necessary while charging batteries.
TM NiMH battery charger with automatic “peak detection” Supplied and Required Equipment recommended. Supplied tools: 2-Way wrench Transmitter / Receiver BIND Plug DYN4044 Vision Peak 2 AC/DC Charger Using your charger: Four (4) Hex Wrench “L” shaped .050, 1/16, 5/64, and 3/32 If you do not yet have a charger a peak-detecting charger will provide the performance required and take care of your expensive batteries.
TM If you are going to be using a charger other than a peak detection charger it is important to have your battery fully discharged prior to recharging. Many of these have a 15-20 minute timer that allows you to set to the amount of charge time. If the battery was not fully discharged from prior use, you can potentially over charge your battery pack. Do not charge any battery unattended, and monitor for heat build up. If the battery pack is more than warm to the touch immediately discontinue charging.

TM Losi LSR-3000 Radio System The Losi LSR-3000 Radio System with Spektrum™ 2.4GHz DSM® Technology radio system included with the Desert Truck operates on 2.4GHz and provides 79 unique channels, which are automatically selected when the transmitter and vehicle are turned on. The communication between the transmitter and receiver begins in the few seconds after both are turned on. They are bound together from the factory to uniquely operate together.
Steering and Throttle End-Point Adjustment Pots (4) Receiver There is no adjustment required of the receiver. Please note the different slots for connection. Auxiliary Channel Throttle Channel Steering Channel Binding Port There is Bind, channel one, channel two and auxiliary slots. The bind slot is used to bind the transmitter to the receiver. The Losi LSR-3000 DSM® radio system uses a unique GUID ID to “bind” the transmitter to each receiver.
TM Driving the Desert Truck Please note the following precautions before running your Desert Truck. • The Electronics in this vehicle are not waterproof and you must avoid running the vehicle in or through standing water, wet grass, mud or snow. • This vehicle is quick: o Do not run the vehicle if it will be out of sight for any amount of time. o Do not drive your vehicle near a crowd of people. • Perform a check of the vehicle before going out to run it. o Ensure the tires are not coming off the rims.
TM Tuning, Adjusting & Maintaining the Desert Truck Tuning the Front End of the Desert Truck Shock Location: The Desert Truck has two mounting locations on the front shock tower. The position can be easily adjusted by simply moving the top of the shock to another hole. The standard location (outside hole on the tower) works best on most surfaces. Moving the top of the shock inward a hole will slow steering response and make the Desert Truck smoother in bumps.
TM Inboard Camber Location: The Desert Truck has three different inner locations with vertical adjustment for the front camber tie rod. In general, the lower or further out the inside position is, relative to the outside, the more camber gain (total camber change through the total throw of the suspension) is present. This is an adjustment that is difficult to make a generic statement for as it can have slightly different results on various conditions.
TM but provide more on-power steering on high traction surfaces. Pro-squat will also help the Desert Truck from pulling wheelies on high bite surfaces. Also available is an aftermarket part that is a 0 degree rear pivot block (LOSA2112), if pro-squat is desired it is best to start with this option. Tuning the Rear End of the Desert Truck Shock Location: Moving the shocks out on the arm will result in less forward traction and let the Desert Truck make more of an arc through the exit of the turn.
TM Adjusting Gear Mesh Battery Position: This is a critical adjustment that is often overlooked but can be very useful. Start by running the battery spaced in the middle (standard setup with 6-cell battery pack). Moving the battery back can improve rear traction on slippery surfaces and steering response. Moving the battery back too far can cause the rear end to swing through turns on some tracks and “dump” the rear end causing instability issues. This is a result of having the weight too far back.
TM Vehicle runs slowly/slow acceleration: Troubleshooting your Desert Truck Check the battery connectors. Confirm that battery is charged. Many questions are the result of simple user errors or minor adjustments which are easily addressed. If after reading below you cannot resolve your problem, then please call Horizon Customer Service at 1-877-504-0233. Vehicle will not reverse: Make sure the throttle trim is at neutral. Radio system does not work properly: Recalibrate/Setup the ESC (see page 9).
