Replacing The Rotor Blades - Revell Control BIG ONE PRO Manual De Instrucciones

• Make sure to return the thrust controller on the remote control to the lowest position after an "emergency landing" in order to prevent damages to the electronics and rotor blades.
• Always completely switch off the flying machine and remote control after use and unplug the plug on the cable for the flight operation on the helicopter. Otherwise a start command
could follow accidentally.
If the rotor blades on the helicopter become damaged and have to be replaced, switch the remote control to "OFF" and disconnect the plug from the helicopter battery. Then proceed as follows:
Ensure before installation
that you have not mixed
up the rotor blades. The rotor
blades are marked
"A" and"B" (see Fig.)
Type "A" rotor blades are
installed on the top and type
"B" rotor blades are installed
below.
1. Remove the casing from the helicopter as shown (fig. 1 a/b)
2. Open the retainer braces with a Philips screwdriver and
remove the battery (fig. 2)
3. When inserting a new Li-Po battery, pay attention to the
same position so that the distribution of weight and the flight
performance of your helicopter remains the same (fig. 3).
By the way: suitable Li-Po batteries can be found at
www.revell-control.de/Ersatzteile!
4. Ensure the secure hold of the battery by using double-sided
sticky tape if necessary, and by tightening the retainer braces.
Place the casing back on the fuselage (fig. 4).
5. Pay attention to the disposal information for the battery on
page 1.
