Introduction
close resemblance to the drone DJI
Package contents
- Quadcopter QW350-2 (with lithium-polymer battery 3S 2700mAh 20C with JST-connector)
- Control panel (powered 4 AA batteries, batteries included)
- Charger (for quad batteries)
- Charger (for remote control batteries)
- Smartphone holder (to use your phone as a camera)
- 8 spare rotors (8045 4 CW / 4 CCW)
- Tool
- Manual (English and Chinese)
- 8 stickers (glued to drone arms, 4-blue; 4-red)
Review
- The battery compartment is large enough, especially in height.
- 433MHz antenna is located on the rear right support of the quadcopter.
- 5.8GHz antenna located inside the battery compartment
- Equipped with the same type of LEDs as the DJI Phantom
Without battery, the QW350-2 weighs 624 grams. The battery adds a whopping 183 grams to the quadcopter. With a battery, the weight of the drone is 807 grams.
In the test, the Chitwan QW350-2 quadcopter showed a maximum flight time of 15 minutes.
Disassembly
The quadric is disassembled very easily and quickly, 3 minutes is enough and you can clean the drone from dust and dirt from the inside. We note the excellent quality of the soldering.

There is no information about the maximum current. The quality of the soldering is excellent!
Control chips
A free BGC port has been noticed, probably for gimbal control. I was pleased with the presence of a UART port, which allows you to connect telemetry via Bluetooth.

FPV camera
FPV camera is good. By adjusting the light sensitivity and color rendition, you can significantly improve the image quality at the output, which is important for confident FPV flight.
VTX
5.8GHz VTX is located under heat shrinkage, power is 400mW. Works in the "boscam" range.
Control equipment
The console has a non-standard shape and assumes an "American" grip (when sticks can only be moved with two thumbs).
Assignment of switches and buttons PWR
- Power button - divided into three positions (charging mode, off / on.)
- Two 2-axis joysticks ("Throttle" left stick)
- Left 3-position switch - responsible for changing flight modes, where: STAB - stabilization, ATLH - altitude hold, LOIT - holding the current position;
- Right 3-position switch - responsible for changing flight modes, where: OFF - disabling the toggle switch itself (for example, when using the left switch modes); RTL - return to take-off point; LAND - return to take-off point with landing.
The RF chip supports the operation of the equipment at three different frequencies:433/700/800 MHz, which is good news.
FPV monitor
4.3-inch (10.9cm) monitor without any sun protection (a visor for example), because of this it is extremely difficult to see anything on the display in sunny weather. The picture quality is below average, but you can improve it by adjusting the contrast and brightness. There is RP-SMA connector for 5.8GHz antennas. And a little to the left of the connector is a tiny button designed to switch between 9 boscam frequencies (by default it is set to 5945 MHz, the eighth frequency in a row).
Conclusion
(2 09) Pros
- Build quality
- Brushless motors
- Dynamic
- Good 433MHz receiver
- Powerful batteries in the remote control
- DVR in the FPV monitor
- FPV camera
- Price
Cons
- No PC cable included
- Capricious in control (does not forgive mistakes)
- No HD camera included
- The built-in recorder is buggy (may suddenly stop recording)
Pretty good FPV camera, great radio range, thanks for that 433MHz. Before embarking on dynamic flights, it is better to start with test short flights to adapt to control. QW350-2 is very "capricious" in management, you have to get used to it. We can say that the QW350-2 is a practical middle ground between price and quality. Suitable only for pilots who have experience in flying UAVs from this niche.
