fuselage length is 1.25 meters (49.2 inches). The fly weight of the
airplane is 3.1 kilograms (6.8 pounds).
The suggested equipment for this airplane includes:
- Motor: 3520-4220 800-500KV
- Prop: 14-inch
- ESC: 60-80A4S
- Battery: 4S 2200-4000mAh
- Servo: 17g*4pcs
- Radio: 4CH+
Product Usage Instructions:
Pre-Flight Checks:
- Check and adjust servo centering for better control surface
adjustment. - Double-check the spinning direction of the motor to ensure it
is suitable for your model. - Set the center of gravity (CG) at the position marked in the
manual. Add weight to the nose or tail if necessary for optimal
flight performance. - Check the inside of the fuselage to ensure all equipment is
correctly connected. Verify the surface of the heat-shrink covering
material and ensure all screws, bolts, cabin, and canopy are
secure. - Take great care when connecting/disconnecting the battery.
Replace the battery immediately if low voltage or damage is
detected. - The way the internal devices of the fuselage are connected
depends on your transmitter-receiver device. For devices with more
functions, you can simplify the connection. Check your device for
details. - When pairing the power system and transmitter-receiver device
for the first time, set the maximum stroke of the throttle
accordingly.
Safety Precautions:
- This product is not a toy and should be treated as a
complicated and sophisticated flying model. Your safety depends on
correct operation. - Do not fly around restricted locations such as airports,
military bases, residential areas, etc. - Perform a range check of the transmitter to ensure no
interference is experienced. - Always turn on the transmitter before turning on the receiver
and turn off the receiver before turning off the transmitter. - If you are a beginner to radio control model flying, seek
assistance or advice from advanced expert fliers before attempting
to fly. - Keep relevant items out of reach of children.
- If performing high-stress flying, take necessary steps to
control movement range and reinforce body strength. - Some parts of the product may cause eye and skin discomfort.
Wear goggles or dust-proof clothes when needed. - The glue mentioned in the list may not be included due to air
traffic safety control. Purchase the glue you need at a local
stationery store.

PRE-FLIGHT CHECKS
Check/adjust servo centering, in order to adjust the control surface better.
Double-check the spinning direction of motor at first usage, and sure it’s suitable for your model.
CG Set the center of gravity (CG) at the position that manual already marked out. If necessary, add weight to the nose or tail to ensure the best flight performance.
Double-check the inside of the fuselage, make sure all the equipments are correctly connected; Check the heat-shrink covering material’s surface, Make certain all screws, bolts, cabin and canopy remain secure.
Take great care when connecting/disconnecting the battery, pls replace the battery immediately once found low voltage or damage to battery.
The way the internal devices of the fuselage are connected will be related to your transmitter-receiver device. For those transmitter-receiver devices with more functions, you can simplify the connection of the internal devices of the fuselage. Check your device for details to see if it meets the features you need.
When the power system and transmitter-receiver device are paired for the first time, you may need to set the maximum stroke of the throttle. Please set it yourself.
SAFETY PRECAUTIONS
14 This product should not be considered a toy, but rather a complicated and sophisticated flying model. Your safety depends on how you use and fly it, If not correctly operated, could cause injury to you or your family members. Children must be accompanied by an adult at all times if operating this product. Not suitable for children under the age of 14. THIS IS NOT A TOY.
Do not fly around some restricted location like airports, military bases, residential areas, etc.
You will need to range check the transmitter to be sure you are not experiencing any interference.
Always turn on the receiver last after turning on the transmitter and shut off the receiver first before turning off the transmitter.
If you are only a beginner to the radio control model flying, do not attempt to fly your model without any assistance or advice from advanced expert fliers.
Keep relevant items out of reach of children.
This product has been flight tested to meet or exceed our rigid performance and reliability standards in normal use,if you plan to perform any high-stress flying, you are solely responsible for taking any and all necessary steps to control movement range and reinforce the body strength.
This product may include some fiberglass and carbon-fiber reinforced plastic parts,which may cause eye and skin discomfort,pls wear the goggles or dust-proof clothes when needed.
Due to air traffic safety control, the products you receive may not have the glue that appears in the list. Please understand and purchase the glue you need at your local stationery store.
