According to my last news I have, the future batch of the Aurora 100 will be shipped with 2.0mm lower carbon frame … so it should be much more durable to crash.
After the promising but in practice dispointing Eachine Aurora 90, here is the Eachine Aurora 100. This time bye bye the full carbon based prop guard system and the X design. Here we have more a 98mm machine with a classic H design. But all the electronic remains the same: strong F3 omnibus FC with a builtin betaflight OSD, 10A 4-in1 BLheli_S/Dshot 600 ESC, 600 TVL 25mW AIO FPV camera, 1104/7500Kv brushless motors, and a builtin buzzer. As for most recent Eachine model, three choices of receiver are available: DSM2/X spektrum, Flysky AFHDS-2A, and FrSky D8. Let’s check this new model.
+ 1 x Eachine Aurora 100 (with a 2S 450mAh LiPo with JST connector)
+ 4 x Green spare props (2 CW, 2 CCW)
+ 1 x Screwdriver
+ 1 x M2 Allen key
+ 2 x Rubber band
+ 1 x Velcro band
+ 1 x Instruction manual (English)
The two rubber bands can be used to fix the battery. One through upper arms, the other one via the lower arms. The two circled piece of foam are in practice usefull to fix the AIO camera behind the red camera support.
The 98mm machine as the EA90 includes the Eachine minicube, a compact three layers boards system. The lower board is the 4-in-1 ESC + PDB, the second is the F3 board while the top one is receiver.
The main lower structure is full 3K carbon based with 1.5mm of thickness.
With the battery strapped playing the role of landing gear.
The CL antenna is no more protected and directly exposed to crash. More, the FPV range will be impacted by the low profile positionning of the antenna.
The left side now offer a clear access to the microUSB port :). Moto”s wires are directly soldered. on each latteral side.
The rear LED bar is fully programmable via betafligh and bonus for the EA100, the larson scanner effect is here
A large and relatively loud square buzzer is installed on top
For the FrSKy receiver, the bind button is positioned on top
A unique carbon plate with builtin arms.
ESC chips. I advise to cover the lower PCB with liquid electrical tape.
with battery strapped
94.3g with the battery and the velcro strap, it’s 13-14g lighter than the EA90
Motors & props
Racestar 1104 motors 7500Kv. They should be 3S compatible.
Same 2035 racerstar quadriblades as for EA90. Shaft section is 1.5mm.
Good news, the spare ones are green, so you can easily mixed them to improve LOS flights.
Exactly the same 450mAh with main certainly an overrated 80C for discharge rate.
FPV AIO module
The same AIO 5.8G 48CH 600TVL camera but a with a three leaves antennna. The FOV is not officially announced but not too large, probably around 120 degrees. Good news, the camera is well fixed in the red aluminium mount dislike the EA90. It will reduce even more the jello effect.
The lens orientation can be ajusted via the two upper latteral screws.
The 48CH module present two tiny button. The first front one flip/Mirror the video but if keep pressed more than 2s, it cycle between NTSC (default) and PAL system. The rear button is shortly pressed selects one of the 8 Vfreq in the current Vband and if long pressed cycles among the six supported bands

UNBOXING, ANALYSIS, BINDING, CONFIGURATION AND DEMO FLIGHT
Whaoohhh … this machine out of the box is super fun. Good news, actually no more weird behaviours, drifts in angle mode, sudden rear right motor thrust lost. I hope versus time and crash it will be definitively confirmed especially the drift effect in angle mode. The machine is clearly more powerfull. 13g less and it make a huge difference. Punch outs are very good despite being a 2S system only. I noticed some vibrations can be heard with high throttle inputs, probably due to the flexibility of arms..In another hand, no jellos can be observed in the FPV link. Of course, now props are much more vulnarable to crash and you will have to stock a lot as spare. The FPV camera offer correct light sensitivity and for FOV well adapted for outdoors application. THe FPV range is IMHO a little bit negatively impacted by the low positionning. Flight times are around 3min30 in average.
Another demo in more open space
There are some positive confirmations. The AIO camera works well, no real problem to reach 100m of range. The machine is super smooth in acro… and mine didn’t show any sign of drift in angle/horizon. Punch out are just impressive… a real monster of power. In the other hand, I observed some inexpected “Flip of the death” at the end of roll ….. Really strange. … the machine became completly crazy and rolls ultra fast during several tour …. And without miracle after the third big crash, an arm broke :(. I recommand to order spare lower plate: http://www.banggood.com/Eachine-Aurora-100-Mini-Brushless-FPV-Racer-Spare-Part-Bottom-Plate-3K-Carbon-Fiber-p-1131282.html… or maybe another alternative is to move completly all the electronic on the Eachine Firer 110 (or 80 ?) frame: http://www.banggood.com/Eachine-Firer-110-110MM-Micro-Brushless-FPV-Multirotor-Racing-Frame-19_5g-3K-Carbon-Fiber-p-1131317.html
After the lower replacement, according to the FyreSG’s videos, I upgraded to BF3.1.6, applied some other PIDs (basically with lower D values) and limit max rates to 800deg/s and from now, no more observed FoD !!!
With fully working, this machine is a real monster and one of my best flyer currently… So much fun with.
The Aurora 100 is clearly far superior to the EA90 in term of stability and power. All problems of the first model seem over. This machine is a super outdoors acro flyer. The builtin betaflight OSD is a great addition. In the other hand, the price is the durability probably less important with thin 1.5mm arm, and the absence of prop and antenna guards.
+ Powerfull machine
+ Stable and great acro flyer
+ No more drift/motor thurst lost as for the EA90
+ F3 Omni FC
+ Dshot600 ESC
+ Betaflight OSD
+ Builtin Buzzer
+ Easy microUSB access
+ AIO camera can be uptilted and is better fixed
+ LED bars including Larson effect
+ Comes with Betaflight 3.1 well tuned with default factory
– Fragile arm section
– Potential “Flip of the death” ?
– No more prop guard
– Cloverleaf antenna exposed
– Fragile props
– 3min-3min30 of flying duration
