Be sure to read these Safety Notes before you assemble your 

model. Always keep to the procedures and settings recom-

mended in the instructions.

If you are operating a radio-controlled model aircraft, heli-

copter, car or boat for the first time, we recommend that you 

enlist an experienced modeller to help you.

Safety Notes

Radio-controlled models are not toys in the usual sense of the 
term. Young persons under fourteen years should only be allowed 
to operate them under the supervision of an adult.

Building and operating these models requires technical expertise, 
manual skills, a careful attitude and safety-conscious behaviour. 
Errors, negligence and omissions in building or flying these mo-
dels can result in serious personal injury and damage to property.

Since the manufacturer and vendor are not in a position to check 
that your models are built and operated correctly, all we can do 
is bring these hazards expressly to your attention. We deny all 
further liability.

Helicopter rotors, and all moving parts generally, con-

stitute a constant injury hazard. It is essential to avoid 

touching such parts.

Please bear in mind that motors and speed controllers 

may become hot when operating. It is essential to avo-

id touching such parts.

Do not stand close to the hazard area around rotating parts 
when an electric motor is connected to the flight battery.
You must also take care to keep all other objects away from 
moving or rotating parts.

Observe the instructions provided by the battery ma-

nufacturer.

Overcharged or incorrectly charged batteries may explode. 
Take care to maintain correct polarity.

Ensure the equipment is protected from dust, dirt and moisture 
contamination. Do not subject the system to excessive heat, cold 
or vibration.
Use the recommended charger only, and charge the batteries only 
for the prescribed period.
Check your equipment for damage at regular intervals, and re-
place defective components with genuine spare parts.
Do not re-use any devices which have been damaged in a crash or 
by water, even when they have dried out again. 
Send the equipment to the robbe Service Department for che-
cking, or replace the parts in question. 
Crash or water damage can result in concealed defects which may 
lead to failure in subsequent use.
Use only those components and accessories which we specifically 
recommend.
