Losi/Horizon Support

If you have any questions concerning setup or operation of 

your 810 RC vehicle please call Horizon Customer Support. 

Contact information can be found in the warranty section of 

this manual.

Getting Ready

Thoroughly read all the enclosed material, precautions and 

follow instructions to avoid damaging your new RC vehicle. If 

you choose to not follow these steps or instructions, it will be 

considered negligence.
If after review of this manual and prior to running your 810, 

you determine this RC vehicle is not what you want—DO NOT 

proceed and DO NOT run the 810. If the 810 has been run, 

your local hobby shop will not be able to process a return or 

accept it for exchange.

Safety Precautions:

THIS PRODUCT IS NOT A TOY! The 810 is a sophisticated, 

high-performance radio control model which needs to be 

operated with caution and common sense. Failure to operate 

this model in a safe and responsible manner could result in 

personal and/or property damage. It is your responsibility 

to see that the instructions and warnings are followed and 

precautions adhered to.
The 810 is not intended for use by children without direct 

adult supervision. Losi and Horizon Hobby shall not be liable 

for any loss or damages, whether direct, indirect, special, 

incidental, or consequential arising from the use, misuse, or 

abuse of this product or any product required to operate it.
*This is still only a model – do not expect it to do unrealistic 

stunts. 

Warnings:

The 810 is powered by a special fuel containing flammable 

liquids and special care must be taken as noted below.

• 

Model fuel is dangerous if handled carelessly. Follow 

all directions and precautions on the fuel container. 

NEVER drink fuel - call a doctor immediately if ingested 

or splashed into your eyes. 

• 

Keep fuel and all chemicals out of the reach of children.

• 

Always keep the fuel container closed and never use 

around an open flame or while smoking.

• 

The exhaust emits poisonous carbon monoxide fumes. 

Always run your model in a well ventilated area and 

never attempt to run it indoors.

• 

The top of the engine and the exhaust pipe are 

extremely hot during and after use. Use caution not to 

touch these parts, especially when refueling.

• 

The engine can be loud especially when run in a 

confined area. If you find the noise objectionable make 

sure to use ear protection.

• 

This model is controlled by a radio signal that is subject 

to interference from sources outside your control. 

Interference can cause temporary loss of control so it is 

advised to always keep a safety margin in all directions 

to avoid collisions.

• 

Always operate your model in an open area away from 

people and cars. The potential speed of this model can 

cause injury or damage.

• 

Never operate your 810 with low transmitter or receiver 

batteries – especially AA dry cells as control and power 

will be limited.

• 

Repeated or prolonged use of heavy braking will cause 

the brakes to overheat and fail! Always leave plenty of 

room for stopping.

• 

It will take as much room to stop as it does to 

accelerate to speed. Always run in an open area with 

plenty of braking room.
