Mini FPV racers are becoming increasingly popular, and the Eachine
Aurora 90 allows you to get in the air in no more time than it takes to
charge the battery. This 90mm quad has a tough carbon-fiber frame,
including guard rings around the props and loops to protect the cloverleaf
antenna. This makes it extremely crash resistant and even allows it to
bounce off obstacles, like race gates, and continue flying.
Its Minicube F3 flight controller uses the popular Betaflight programming app. The built-in on-screen display provides flight data and an
artificial horizon, and it can be customized in Betaflight. The Aurora is
available with bind-and-fly receivers for Spektrum, FrSky, and FlySky
transmitters, and the receiver includes a buzzer to make the quad easier
to find. The Minicube 4-in-1 speed control uses BLHeli_S firmware and
the latest DShot600 protocol for super-fast motor response. The tiny
CMOS camera provides a remarkably clear 600 TVL picture, and the
25m W video transmitter supports eight channels on A through F bands,
for a total of 48.
The quad is 100 percent prebuilt, so all that’s needed is to charge the
included 2S 450mAh LiPo and then bind and set up your transmitter
using Betaflight. Access to the micro USB port is pretty snug, but I found
that by shaving the plastic on my cord, I could make it fit without resorting
to disassembly. The setup process in Betaflight is straightforward, given
that the flight controller is mostly preprogrammed. I did have to increase
my throttle travel to 120% to get the motors to arm, a common require-
ment for Spektrum radios.
Even in Horizon flight mode, the little quad is remarkably speedy but
stable enough that a pilot with minimal quad experience can keep up. Any
time you get confused in Horizon mode, you can just release the sticks
and it will return to a level attitude. In full Acro mode, the handling is a lot
sportier, and it will do quick flips and rolls.
With its small size and agile handling, the Aurora is a ball to fly on
tight racecourses or for just dodging around trees and obstacles in your
backyard. The video range is surprisingly good for just 25m W. The flight
duration with the supplied battery is three to four minutes, and with a
2S 800mAh pack of suitable C rating, duration is up to five minutes.
Overall, the Aurora is a fun machine that’s ideal for FPV beginners or for
one-design club racing. It’s available from U. S. suppliers, such as
excelrc.com, for $180.00, and direct from banggood.com for $150.00
plus shipping.—Jim Ryan
