General:

The Speed-T is not a toy. This product is not intended for

use by children without direct adult supervision.

This RC Vehicle is not intended for use on public highways

or roads.

Avoid an area that has many pedestrians or crowds

of people.

Keep in mind that this vehicle is radio controlled and

can experience moments of radio loss or interference, so

provide for a margin of error at all times.

Please be aware that the motor and batteries of this

RC vehicle will get HOT during each use. Be careful not

to burn yourself.

It is not recommended to run this RC Model at dusk and

into the evening or if you will lose sight at any point while

running the vehicle.

Electronic Speed Control (ESC):

Read all safety precautions prior to each use.

Never leave the vehicle/ESC unsupervised while it is

switched on, in use or connected to a power source. If

there is a short or product defect, it could result in fire.

If there are exposed wires, do not use the ESC until you

have installed shrink-wrap or replaced the wire.

Disconnect the battery from the ESC after use.

The ESC is not water proof and should not be exposed

to moisture.

Do not attempt to use more than 3-cell LiPo or seven

cells NiMH; doing so will damage the ESC and could

result in fire.

Always turn on the transmitter first then the ESC to

prevent an out-of-control vehicle.

This is a High Performance Brushless System
