: Please check whether the transmitter antenna is defective or has not been fully extended. If another RC model is nearby, make sure it is not using the same frequency. If so, please change the frequency.
Vehicles
Check to make sure the antenna on the controller is screwed in all the way. Then pull the antenna out completely. For the antenna on the vehicle, use the clear antenna tube included in the package (depending on the model).
Open the vehicle chassis and clean the axles of dust and hair. Also, apply a drop of oil (resin- and acid-free grease) to the axles.

The ON/OFF switch is located on the left side of the vehicle, right next to the battery compartment.
There is a sticker on the back of the controller and on the vehicle near the drive axle that shows the correct frequency.
Boats
Let the water drain off and dry your boat thoroughly after use. Use regular tap water to clean your boat. The contacts on the water sensors should be treated regularly with vinegar cleaner to prevent corrosion. Make sure the vinegar cleaner does not come into contact with the propeller or rudder. This could cause permanent damage.
Here’s how to drain your boat properly:
Falshöft Coast Guard Boat (301001/301005)
After each trip, please open the two drain plugs at the bow and stern and, if necessary, drain any accumulated condensation. Please make sure to reinsert the drain plugs into their designated openings before each trip.
Ferrari Boat Arno XI (300005)
There is a drain plug at the stern. Open it after every trip to drain any condensation. Please make sure to reinsert the drain plug into the designated opening before every trip.
Power Wave (300001)
You’ll find the drain button on the underside of the boat, between the propeller and the sensor. Press it down with a blunt object until the condensation has drained from the boat. Since the drain button is spring-loaded, it will automatically return to its original position as soon as you stop pressing it.
Please note that, for safety reasons, the connection can only be made in the water. When starting up, turn on the controller first, then the boat. After the trip, follow the reverse order—turn off the boat first, then the controller.
Our boats are designed for use in fresh water with normal to moderate waves.
If your boat does come into contact with dirty or salty water, it must be thoroughly rinsed with regular tap water afterward.
If the battery in your boat or vehicle has been connected correctly and the charging process is proceeding normally, the red LED will remain lit. When the battery is fully charged, the red LED will turn green. The battery can then be removed and installed in the vehicle or boat.
Aircraft
If your micro quadcopter (502002) does not take off even though the battery is fully charged, please check whether the 4 rotor blades are arranged correctly. The letters are stamped on the top of the rotor blade. It is important to position the A/D rotor blades and the B/C rotor blades correctly.
Before your first flight, please make sure to check whether model aircraft are subject to mandatory insurance requirements in your country. For more information, contact the German Model Aircraft Association. Here’s what you’re not allowed to do with your model aircraft:
- Fly near airports without permission (minimum distance: 1.5 km)
- Fly over crowds of people, military installations, hospitals, power plants, or correctional facilities—please make sure you always maintain direct visual contact with the aircraft.
- Flying in windy conditions or bad weather,as well as under the influence of drugs or alcohol, is prohibited.
Please follow these steps to properly pair the controller with your helicopter:
1. Turn on the helicopter.
2. Turn on the controller.
Exception: For the Sky Hunter (501001) and Red Eagle (501002), follow this procedure:
1. Turn on the helicopter
. 2. Press the right control stick on the controller and then turn it on.
Applies to the following helicopters:
Thunder Storm (501004),
Helicopter (501007),
Green Chopper (501003),
Orange Sply (501005),
Green Vecto (501008),

. Proper trim is essential for stable flight performance. Adjusting the trim requires a bit of patience and finesse.
Please note the following instructions:
Carefully move the throttle lever on the controller upward and let the helicopter climb to a height of approximately 0.3 to 0.8 meters.
If the helicopter is hovering in place and turning to the left or right without any movement of the tail (circular rotation) lever, please proceed as follows: If the helicopter rotates on its own—either quickly or slowly—to the left around its own axis, gradually push the lower right trim control for tail (circular rotation) on the controller to the right. If the helicopter turns to the right, gradually push the tail trimmer (circular rotation) to the left.
If the helicopter flies forward or backward while hovering—without moving the forward/backward control stick—please proceed as follows: If the helicopter moves forward on its own, either quickly or slowly, gradually push the upper-right forward/backward trim on the controller downward. If the helicopter moves backward, gradually push the forward/backward trim upward.
Applies to the following helicopters:
Sky Hunter (501001),
Spider Fox (501006)
. Proper trim is essential for stable flight behavior of the helicopter. Adjusting the trim requires some patience and a feel for it.
Please note the following instructions:
Carefully move the throttle lever on the controller upward and let the helicopter climb to a height of approximately 0.3 to 0.8 meters.
If the helicopter drifts to the left or right while hovering without any movement of the left/right roll lever, please proceed as follows: If the helicopter moves sideways to the left on its own—either quickly or slowly—gradually push the lower right trim lever for right/left roll on the controller to the right. If the helicopter moves to the right, gradually push the right/left roll trim lever to the left.
If the helicopter spins in place to the left or right while hovering, without moving the tail (circular rotation) control stick, please proceed as follows: If the helicopter spins on its own—either quickly or slowly—to the left around its own axis, gradually push the lower left tail (circle) trimmer on the controller to the right. If the helicopter spins to the right, gradually push the tail (circle) trimmer to the left.
If the helicopter moves forward or backward while hovering without any movement of the Forward/Backward control stick, please proceed as follows: If the helicopter moves forward on its own, either quickly or slowly, gradually push the upper-right Forward/Backward trimmer on the controller downward. If the helicopter moves backward, push the forward/backward trim control up in small increments.
