Eachine Falcon 120, the test

It is a very small racer in X, with brushless engines, which can fly indoors ... but by proceeding to a home-destroying session. More seriously, it is a machine intended for outdoor flights, a small perfect car for nervous flights without the need for vast spaces. Note that this device was given to us by the Banggood shop. As usual, tell us if you think the practice has influenced our judgment.

Tour of the owner

The Falcon 120 deserves its name, it measures 12 cm diagonal of motor motor. It is made of a main carbon plate drawn in X, with a thickness of 2 millimeters. Under this plate is glued a thickness of foam. The central block has been thought to be compact, it is stackable, or "stackable" in English. It is made of 3 floors. The first is an ESC 4 in 1, a Racerstar RS20A model which as shown offers 4 ESC of 20A compatible in 2S, 3S and 4S, BLheli_S, Oneshot42, Multishot, DShot600. The top floor is the flight controller, a SP Racing F3 model on the Falcon 120 that I tested. The last stage is a carbon plate on which the camera is fixed, with the help of a hinge designed to tilt it. The camera is a 700TVL model with an angle of 127 °. Under the plate is housed the video transmitter, featuring a RP-SMA angled connector and a short base mushroom antenna. It is a transmitter with a power of 200 mW, so it is too powerful for French regulation. It transmits over 40 channels, including the ImmersionRC Raceband.

Continuation of tour

On the plate, on the outside, is the AFHDS 2A 2.4 GHz radio receiver for a Flysky radio control in the RTF version of the Falcon 120. The floors are held by metallic red aluminum spacers. At the rear of the machine is a bar of 6 LEDs centered around a buzzer. Under the device comes an XT60 plug for the battery. Which is to place under the device, without nacelle, with a scratch Velcro. The engines are Racerstar BR1306 to 3500KV delivered with 3-inch quadrilateral propellers (3030-4). The battery supplied with the Falcon 120 is a Lipo 3S 11.1V 850 mAh, with an XT60 plug. The weight of the Falcon 120, without its battery, is 149.32 grams. The supplied battery adds 83.11 grams. Or 232.5 grams in order of flight.

Before taking off

As always, it is prudent to go check the parameters of the device, taking the precaution to remove the propellers. A microUSB connector is located on the back right side of the center block. It is located just in front of the axis of an engine, which makes the insertion of a USB cable a bit difficult. The firmware of the flight controller is Betaflight, version 3.0.1. All settings were made at the factory: PIDs, spleens, channels, etc. All that remains is to choose the arming method and the switch for the choice of the flight modes. The Failsafe must also be adjusted. It is quite easy, on the side of the radio control, a Eachine i6 (a Flysky FS-i6), since the protocol is the AFHDS 2A which supports the Failsafe.

First take-off

It happens in direct sight flight, as usual. The behavior of the Falcon 120 in Angle (stabilized) mode is very bright, almost too much for novice pilots. But we do it quickly. The machine is generally stable, however there are some oscillations, probably PIDs which can be improved. In Horizon mode, the angle grip is fast, allowing barrels and looping in a pocket handkerchief. Visual flight is the opportunity to adjust the video frequency. The principle is simple, a button on the video transmitter, not super simple access, allows to pass the 40 channels of the 5.8 GHz sequentially. It is a bit painful, especially since there is no visual indicator of the frequency and band chosen.
