Introduction
Eachine – for the entire time of its existence in the unmanned market, it has offered the consumer a huge number of drones, some of which the company can be really proud of, but some are better not to remember. Eachine Racer 250 is one of the first drones built on B / C motors, which at one time received recognition from both experts and amateurs. And who would have thought that the manufacturer would return to the popular model in almost two years, where, after significant improvements, the drone would again be ready to surprise its fans. We are glad to present you an old, but at the same time completely new drone – Eachine Racer 250 Pro.
The materials of execution remained unchanged, almost the entire electronic filling underwent modernization, and the drone also received a more symmetrical X-shaped frame.

Motors
Eachine Racer 250 Pro, unlike its predecessor, is equipped with more powerful 2205 motors, with a power of 2300KV. Visually, the Pro motors are very similar to the Eachine Racer 180 motors. Despite the weight of the ER250 Pro at 473 grams, they provide an exponential dynamics that everyone will notice without exaggeration.

Camera
The Racer 250 Pro is equipped with a classic 1000TVL CCD FPV camera that works with both NTSC and PAL systems (default). In Pro, it now has a variable angle of inclination up to 25 °. It has proven itself in practice even when flying at night.
The fact that the camera has a variable angle is very good, but now when you move it to the highest position, part of the drone’s front panel enters the frame. We’ll have to “collective farm” to get rid of such a minus.
CCD sensor (Charged Coupled Device) – converts pixel charges into an analog signal. Such cameras have a lower noise level and high sensitivity, and they can easily cope with interference, which, as a result, significantly affects the picture quality.
Food
Eachine Racer 250 Pro comes with a 1199mAh Lithium Polymer 4-cell battery with a 30C discharge rate and an XT60 connector. The same Eachine Racer 180 is equipped with a similar battery. According to the specification, it provides a flight time of 8-10 minutes. In practice, this time was 5-6 minutes.
Control
The RTF bundled with the Eachine Racer 250 Pro is the classic 6-channel equipment FlySky i6, made under the Eachine brand. It runs on the fault-tolerant AFHDS-2A protocol, which is good news in itself. Allows you to easily be removed to a distance of more than 400 meters.
It is worth noting that the quad reaches the owner with an expired version of the CleanFlight firmware (1.13). As a result, the latest firmware of the CF-configurator cannot even open the settings. In this case, it is highly recommended to install Betaflight. With it, the drone behaves much better, it is more stable, the flight is smooth without vibrations.
Price
Eachine Racer 250 Pro is sold on various Internet marketplaces. Depending on the configuration, the drone can be purchased:
- PNP Version – $129.99
- RTF Version – $219.99
Conclusion
Eachine Racer 250 Pro from $130
pros
- Powerful
- Stable
- Relatively silent
- Lighter than predecessor
- Flight Controller SPF3
- 20A ESC BLheli_S/Dshot 600
- Flight duration (more than 5 minutes)
- Powerful front lighting
- Good camera at 1000TVL
- Strong signal FPV/OSD/Buzzer
Minuses
- Unfortunate and weak location of the VTX connector
- The fragile back of the drone
- Jelly in FPV mode
- The front panel of the drone limits the viewing angle at a camera angle of 25°
- Outdated CleanFlight Firmware
In practice, the ER250 Pro proved to be a great drone, provided that the Betaflight firmware is installed. Fast and stable acro quad with good flight times. FPV performance coupled with a powerful VTX and built-in OSD module also deserve special respect. The main disadvantages include the back of the drone, it is not protected by anything and most likely will be more prone to breakage in case of serious crashes. Just like with the VTX RP-SMA, in the event of a crash, this connector will be torn off by the antenna itself, which will subsequently cause the VTX to simply burn out due to the absence of a 50 ohm load. This disadvantage is primarily design costs. In general, the developer can be proud of the improved Racer 250 Pro, the drone is worth the money spent and, without exaggeration, is able to give exceptionally positive emotions from use. Age limit 14+.
