Eachine Aurora 90 preview

Why a simple preview of the Aurora 90? It is a complex multirotor, equipped with brushless motors, which requires time to be thoroughly tested. Many of you were asking me if the device was worth it. I opted for a preview, enough to get a good idea of the qualities and defects of the machine. Note that the 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 Aurora 90 looks like a Tiny Whoop, with four-bladed propellers and duct-like propeller shields. But it is more imposing: as the name implies, it measures 9 cm diagonally of motor motor, and is inscribed in a square of 11,8 x 11,8 cm. It measures 7.5 cm in height without its battery. For comparison, a Tiny Whoop is 6.5 cm diagonal and 8.3 cm side. The weight is quite high: 74.5 grams without the battery, which adds 31.87 grams, for a total flight order of 106, 37 grams. The engines are 1104 to 7500KV. The propellers are 5.1 cm models, or 2 inches, secured with 2 screws. Our previous experience with a nano brushless, the Eachine's X73S, had not been conclusive. The Aurora 90 inspires a lot more confidence, with a carbon structure of 2 mm thick that looks solid enough, protectors of carbon propellers, and a central pod that holds and protects the combo camera and video transmitter 5.8 GHz . Inside the aircraft, there is a Betaflight 3.1 flashed flight controller, a 2.4 GHz radio receiver, and a 4x10A BLeli_S compatible 4x10A ESC compatible Oneshot42, Oneshot125, Multishot and DShot600. At the rear there is a bar of 4 LEDs. It has everything of a great!

Connection under Betaflight

The version I tested is equipped with a Flysky radio receiver. To pair the Aurora 90 with an FS-i6, the procedure is conventional and fast, via the AFHDS 2A protocol. Good news: this means that this multi-rotor Flysky version is compatible with more high-end radio controls than the FS-i6. To connect it to a desktop computer with Chrome Betaflight Configurator, simply plug in a microUSB cable. But we soon realize that it is not going to be as simple as expected. The microUSB connector is present on the outside of the flight controller, but its access is totally blocked by the propeller shields! What has to be done ? Unscrew at least 2 screws of the front-left protection ... What is not simple: the threads are in the axis of the propellers, and therefore difficult to access even with a long and thin screwdriver.

Connection under Betaflight, continued

The flight controller of the Aurora 90 responds well under Betaflight. No worries to match the channels to the joysticks, to configure two switches to arm the motors and choose the modes. But unless armed with the joystick, it lacks a channel on the FS-i6 to trigger the buzzer. Because yes, there is a buzzer on board, and it is very appreciable. Direction the OSD tab: you can choose what you want to see on the screen during the flight. Battery voltage, artificial horizon, center cross, flight time, flight mode, driver name, etc. Friendly! Note that the driver name changes on the Configuration tab. Not all value are available. No GPS, of course, nor altitude without adequate sensors. Also not displaying the video channel ...

Ignition…

The battery delivered with the Aurora 90 is a Lipo 2S 7.4V 450 mAh and a discharge rate of 80C, with a red JST plug. One can doubt the reality of 80C, especially with this hold. The battery is fixed under the device, with a small Velcro. Not really practical, she tends to save herself. As soon as the connection is made, the bar lights up, with high brightness. Friendly! It is plugged in with a small connector, and therefore easy to disconnect. First take-off at sight: the Aurora 90 is quite noisy, but it is very nervous even in Angle (stabilized) mode. Indoors, pushing the gas has every chance to stick the machine to the ceiling! It will be necessary to play on the spleens to calm the beast if you want to practice the precision flights in indoor.
