On this page I will be reviewing the Eachine QX90C It is a new class of 90 aircraft which measures 9cm from motor to motor (diagonally.) Every time a new model of the Eachine comes out, they always look pretty much the same as the previous one in some way. So what is it about the QX90C that separates it from other models?

The Look & Feel Of The QX90C

There is no carbon fiber on this drone. Its frame is made of a rigid yellow plastic, which has the ability to twist and flex a bit in case of a fall. The engines are brushed 8520 and are pressed into the frame to support it. They are well protected but the wires underneath are exposed. The power wires run along the arms to reach the flight controller via a connector. This allows a motor to be changed quickly without welding it into place. The flight controller is an SP Racing F3 EVO with Cleanflight (1.13.0). It has an easily accessible microUSB connector for making adjustments. The flight controller is simply slid into the frame, with a thick foam padding to hold it into place. The assembly of this drone is simple. My only frustration is when you remove the USB cable, you can sometimes pull out the flight controller too.

Look and Feel Of The QX90C Continued

The QX90C uses a 520TVL camera and a 5.8 GHz transmitter with a power of 25mW (which is compatible with European regulations.) This is a common combination of camera and transmitter which we have seen on many other drones. The transmitter is capable of transmitting over 32 channels on Frequencies A, B, C, and D. Does this mean there is no support for the ImmersionRC Raceband channel? I’ll answer this question further down the page! Under the device there is the housing for a battery. The battery is a 600 mAh 3.7V 1V Lipo with “No Voltage Protection” (meaning it continues to discharge even if it exceeds the recommended values.) It weighs 33.57g without the battery and 49.42 with the battery.

Before Taking Off With The QX90C

The QX90C is available in 3 separate versions, each with a different radio. The one I tried uses the Flysky AFHDS. Pairing is very easy. It is important to go through the Cleanflight settings to verify that the channels are associated with the joysticks and make changes if necessary. It is also recommended that you choose the flight mode in Cleanflight (either Angle or Horizon {neither of these are Arco mode though.}) Finally, check that the failsafe is configured to prevent the device escaping from your control in the event of a radio connection malfunction.

First Take Off With The QX90C

As always, our first test was not done in FPV but rather in LOS. This was a pleasant surprise because unlike the Turbine QX70, the QX90C rises very quickly without any difficulty. The steering controls respond well but in a less nervous way than the Inductrix or Tiny Whoop. However, it is up to you – you can change the settings to harden the controls a little.

As it stands, the QX90C is a drone to fly outside as opposed to one you fly inside. It is also deprived of prop protections. I managed to fly it for around 6 and a half minutes before the power began to drop. The drone stops completely after 7 minutes of flight – sometimes a little less if you performed some tricks on the drone. One thing I do love about this drone is the “No Voltage Protection.” This will wear down your batteries in the long term but it will make them last longer. A battery with the same capacity would only have lasted for 5 minutes. So buy a few batteries and you’ll get so much extra flight time!

FPV Flights With The QX90C

The FPV camera is a 520TVL. The definition of the video is poor but that is the same with basically all analog videos. The camera is a wide angle and deals with cameras quite well. Even in the face of difficult environments such as frost of fog (watch the video below) it manages to cope. It struggles a little with contrasting light sources. The car park alternates from light to dark and so you can see some very illuminated areas at times. However it does not prevent you from flying. The range of the transmitter is correct. You can expect to exceed 100m in an outdoor environment without obstacles. Inside you can go through 2 or 3 walls. The frequency ranges as previously mentioned are A, B, C and D. The A is the F / IRC, the B is the A and the D is the E and the C is the raceband. This is a bit weird and I’m not sure why they have done this however this does support ImmersionRC Raceband.

Flying Experience of the QX90C

The QX90C is very nice and stabilized in Angle mode. The stabilization lets you gain a lot of speed and therefore it is perfect for car park flights. This is also the same outdoors but I have found that Acro mode is way better than Angle mode outdoors. The QX90C is also very powerful and can easily perform simple aerobatic flights. If you fly in rainy weather or in fog, be aware that the props are exactly the height of the camera. In a damp environment, they project water onto the lens so in a few seconds you cannot see very much. as shown in the video.

What Happens In A Crash?

The plastic structure seems to hold the drone together and deals with the shock well. This is because it has some flex. I had to fly into a tree trunk to bend the end of an arm a bit. The frame will not, of course, withstand repeated crashes on hard surfaces like car park concrete.

Should You Buy It?

Oh yes! This small QX90C from Eachine is a joy to fly. It lets you have lots of fun outdoors for a very cheap price. Unlike the Tiny Whoop this drone lets you fly with obstacles in the way. It is also an improvement on the original QX90 and the QX95. It has a very distinguished minimalist design and is easy to repair, resistant to shocks and it nice to steer. Get it here.

    I am getting one of these as its perfect for setting up with my frSky, the only thing that is a shame is the props are mid camera, do you think lifting the camera up would massively upset the craft when flying?

      Nope I think lifting the camera up should be fine – although I can’t guarantee it!

    Strange positioning for the camera
