Camber Rise Relationship: The Speed-NT setup out of the box

comes with less front camber gain than the rear camber gain.

The reason for this is that less front camber lets the front end

drive flatter and makes the Speed-NT more stable. By having

more camber gain in the rear, the Speed-NT has more rear

traction, this helps the rear tires accelerate through the bumps

and ruts.

Wheels and Tires

The tires come pre-mounted with the vehicle and should be

checked to make certain they stay glued to the wheels. The

wheel spinning speeds this vehicle is capable of tend to pull the

rubber tire away from the rim. When a tire or tires come loose

from the rim you will notice the vehicle is hard to control.
Tip the vehicle on its side and using both hands to hold one

wheel at a time, use your thumb to press the tire away from the

rim. If you see a tire pull away from the rim use Losi Tire Glue

(LOSA7880 thick or LOSA7881 thin) to re-glue. It only takes a

small drop of glue generally. Be careful this is CA-type glue and

you do not want to glue your fingers to the wheel and tire.

Use safety goggles when gluing tires.

Check the mounting of the tire periodically to ensure proper

performance and handling.

Steering Assembly: Occasionally, check the steering assembly

and you may notice increased looseness. There are several

components which will wear out from use: tie rod ends (part

LOSA6074), the servo saver (part LOSA1610), the bellcrank

bushings (part LOSA1620), and the drag link ball ends

(LOSA6074). You can easily replace these components to restore

factory specifications.

Note: The bellcrank bushings may be replaced with

ball bearings (part LOSA6912).

Troubleshooting your Speed-NT

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

Product Support at 1-877-504-0233.

Radio system does not work properly:

If the power light on the transmitter is not turning on, first

ensure the batteries are installed correctly. You should also

check that the batteries are good and/or if rechargeable are

fully charged. Replace them if needed. If the power light is

blinking, then the transmitter batteries are weak and should be

replaced. If the transmitter light is on but the radio is still not

responding, you may need to re-bind the transmitter to the

receiver. Please see page 16.

Short radio range:

If the radio range appears short, make sure the batteries are all

fully charged and/or are in good condition.

Steering or Throttle servo does not work:

Check all wires, radio system, battery connectors, and the

battery pack.

Engine will not start:

1. Check the igniter by attaching it to a new glow plug. If the

glow plug element does not glow bright red the igniter

needs to be charged.

2. Remove and check the glow plug by attaching it to the

igniter. If it does not glow red attach a new glow plug

to the igniter – if the new plug glows red install it in the

engine. If it does not glow red recharge the igniter and

repeat the test.

3. Make sure there is fuel in the tank.

4. Check the fuel line for holes or cuts.

5. Note that the fuel is getting up to the carburetor. If not

wait for the exhaust pipe to cool and put your finger over

the exhaust tip and turn the engine over watching for the

fuel to go up the fuel line until it gets to the carburetor. Do

not continue to turn the engine over with your finger over

the exhaust tip after the fuel has reached the carburetor.

6. If the fuel has been left open or is over 6 months old, try

replacing the fuel including that in the fuel line.
