INTRODUCTION
With the Eachine Aurora 90 we have a direct clone of the AXC Halo90 . A 90mm brushless machine relatively light with 1306 motors, 2S powered, with a F3 compact board including a builtin betaflight OSD, a 4-in-1 ESC BLheli_S/Dshot600 compatible board and a 48CH 5.8G 25mW AIO 600 TVL camera. The main originality is probably a prop guard full carbon based super strong to impacts. Let’s discover this bundle.
BOX CONTENT
+ 1 x Eachine Aurora 90 (with a 2S 450mAh LiPo with JST connector)
+ 1 x Charger Emax B3pro
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Screwdriver
+ 1 x Allen key
+ 1 x Velcro band
+ 1 x Instruction manual (English)
The instruction manual is fully detailed printed in color. All informations you need can be found there.
OVERVIEW
A 90mm machine.
The main lower square carbon structure is 1.5mm large
while the carbon prop guard is only 1mm
-FRONT VIEW
On the top of front side, the bind button is available for the FrSly D8 receiver.
We have a minitower of electronic with the FrSky D8 receiver on top, the F3 omni in the middle and the PDB/4-in-1 ESC at bottom.
-SIDE VIEW
Harg !!!! the microUSB port is not directly available. The microUSB insertion is completly blocked by the front left prop guard.
If you remove two screws, you can rotate the prop guard and access to the port. More the 2.4G antenna is connected to the receiver via a uFL/IPX connector. Check before the first take off if the antenna is fully inserted into the connector. If you observed some drop out in the signal…. check this point particulary.
-REAR VIEW
4 lights not fully programmed with the LED strip capacity of betaflight. A JST connector…. I strongly advise to install more a XT30 connector.
but bright enough for racer
Just above installed on the FC, a large buzzer relatively loud
-UPPER VIEW
-BOTTOM VIEW
A thin battery strap… not enough to fully attach the battery. You will need to use the velcro band to secure everything
-WEIGHT
106.7g in total …
Motors
1104 brusless redstar motors announced to be 7500KV. Unfortunatly they spin probability too fast for the 3S comptability, at least to not damage them
quadriblade props relatively flexible
M2x8mm hexscrews
A major drawback in the design is the tiny clearance between prop and the red aluminium standoff, less than 1mm in practice !!!!
Especially in fast forward mouvement in combinaison with the flexibility of the prop, you can have a fatal contact breaking mid-air the prop. If you are interested by the EA90, it’s also strongly advised to instal such spacers: https://www.axc-drones.com/axc-halo-spare-carbon-hoop-5.html
LiPo
A 450mAh 2S LiPo with 80C of discharge rate !!!! it’s a lot but I am suprize of the usage of a JST connector. A XT30 connector would have a been much choice in term if peak current supported.
Camera module
The AIO FPV camera is installed out of the box by a simple tape and in practice the installation is far to perfect as soon as the tape is dried. Definitively the installation must be secured with a zip-tie a rubber band. If not some little jello will be present. The lens thread is in M7 format. Installed a 170 DFOV lens, probably too wide for fast outdoors applications.
The VTX part is based on a 48CH module (raceband supported).
a RHCP cloverleaf antenna well protected
Two buttons are located on top of the AIO element. The frontal one selects NTSC/PAL and the rear one select the Vfreq (short press) and the Vband (long press).
Two small lights indicate the current Vband and Vfreq up and down respectively
All the camera support can be tilted from 10degrees up to 30-35 degrees by unlocking the top M2 hexscrews
A raw sample of the performance of the FPV camera
The behaviour in term of light sensitivity is correct, with average performances.
UNBOXING, ANALYSIS, BINDING, CONFIGURATION AND DEMO FLIGHT
No doubt the Eachine Aurora 90 can fly superbly thanks to powerfull motor and efficient BLheli_S ESC. Punchout for a 2S system are really good so definitively acro compatible. The FPV link is good too at least comparable with all recent 25mW AIO FPV combo. The OSD informations are a real positive element. Unfortunatly despite these positive points, there are some negatives ones. First, especially in angle/horizon modes, the machine drift a lot in the left direction despite all calibration procedures. Maybe a a faulty gyro… but some other users already reported also this problem. Another issue is the lost of thrust for the rear right motor after a right turn at high speed. Maybe also linked with the gyro or by the battery sag, it’s still Under inversitigation. Flight duration also are poor, only 3min in practice.
CONCLUSIONS
Despite being on the paper a super machine with great elements, some minor details are considerably limiting the interest of the Aurora 90. First, some spacers and eventually a soft mounting solution (with electrical tape) must be installed to avoid a crash caused by the contact of props and the red aluminium standoffs. The builtin gyro or the battery are probably also guilty…. introducing drifts and motor thrust losts mid-air at high speed. It’s really annoying.
PROS
+ Strong machine
+ Prop guard in carbon

+ Protected AIO FPV camera
+ Color printed instruction manual
CONS
– need spacers installation
– USB port not directly available
– Drift observed in angle mode
– Rear right motor thrust lost mid-air
– 3 min of flying duration
