Product Overview
"9CH" refers to 9 freely switchable channels, which is equivalent to having 9 "expressways" to choose from. When you encounter signal interference during a race or flight, just press a button to switch frequencies, and you can immediately restore a clear image. You'll never have to worry about the awkward moment of "sudden image loss" again!
Compared with ordinary 3-5CH devices, 9CH not only offers more choices but also can work with the "automatic frequency hopping" function (supported by some high-end models) to intelligently avoid congested channels. Especially when multiple people are competing at the same venue, this design is simply a "lifesaver" — whoever switches frequencies first will gain an advantage at the starting line!
Tips: Although 9CH sounds impressive, remember to pair it with a receiver that also supports 9CH (such as FPV goggles or a receiving module) to fully utilize its capabilities.
FPV racing drones emphasize "speed, accuracy, and stability," with every gram of weight affecting flight performance. This 1.2G 4W transmitter focuses on a "lightweight" design, usually weighing only 10-15 grams, nearly half the weight of ordinary transmitters! This means you can save precious battery power, allowing the drone to fly longer and faster.
In terms of materials, most adopt an aviation-grade aluminum alloy shell with a waterproof coating, balancing heat dissipation and durability. The internal circuit layout is compact, and it is often equipped with LED status lights to display the working status in real-time, facilitating debugging. Some models even support external antennas to further optimize the signal coverage range.
⚠️ Note: Although it is lightweight, don't be tempted to buy "uncertified" products for cheap! Regular products will pass certifications such as CE/FCC to ensure compliance with electromagnetic radiation regulations and avoid penalties from local radio management authorities.
Key Features
- Power output: 4W is preferred, balancing penetration and power consumption; some models support adjustable gears (such as 1W/2W/4W) to flexibly cope with different environments.
Power supply voltage: Compatible with 3S/4S lithium batteries (11.1V–16.8V) to avoid restart or damage caused by unstable voltage.
Interface type: HDMI or CVBS input is preferred, compatible with mainstream cameras; some support AV input, suitable for old devices.
