Eachine RedDevil Review

The Eachine Red Devil is available exclusively from Banggood

Introduction
​The Eachine Red Devil is a 120mm "toothpick"class quad: an ultralight micro that is capable of swinging 65mm bi-blade propellers. This quad is very similar to the Happymodel Sailfly-X (which I reviewed here) but with a bump in specifications, particularly around the FPV camera and VTX. You can actually think of this as an updated Sailfly-x much like the Eachine trashcan (reviewed here) is actually an upgraded Mobula7 (reviewed here). Is it better than the sailfly-x though? Mostly less but it does feel like it needs a little extra to take advantage of this. Read on to find more.

What's in the pack?

Like the Eachine Trashcan (and unlike the Sailfly-x) the Red Devil ships with a nice protective zipper case that you can store the quad, some simple spares and batteries in. It also ships with a simple but useful selection of spares as listed below:
The quad itself

• 3 full sets of propellers (12 props) (spares here)
• 3S 11.4v 300mah 30C/60C battery (spares here)
• Propeller disassemble tool
• Screwdriver
• Eachine Handbag

A closer look at the specs:

• Crazybee F4 v2.1 board - The quad is build around this very familiar all in one board. It has a F411 processor that is capable of 8k/8k Gyro/PID loop with all dynamic filters and features. It also includes a 4 x 5A esc that is capable of 2-3s including a very useful current sensor. Lastly it has a built in recevier (Flysky, FRsky or DSM) which makes it compact and light.
• EX1102 8700kV motors - Nice light motors with 2 bearings, identical to the Sailfly-x's motors but supposedly a slightly higher kv.
• Caddx EOS2 FPV cam - A polarising camera this one... I've had good and bad experiences with this cam. Superior to an AIO cam at day but surprisingly doesn't handle the low light as well
• 25-200mW vtx - This is a welcome addition that means I can run more that the 25mW I'm limited to on AIO cams like those on the sailfly x. 
• 2s 300mah 30/60c battery - Nice lightweight battery that suits the Red devil well. Same as the one included with the Sailfly-X

A closer look at the quad itself

Same light but flimsy canopy as the Trashcan

There are a few surprising element to this quad that you wouldn't pick up on from specs alone. Firstly you'd expect that with heavier cam and vtx the quad would weight more than the Sailfly but surprisingly it doesn't - this is because the canopy is much lighter than the hefty 3d printed unit on the sailfly meaning that it comes in at a very familiar dry weight of 38g. This does come at a cost though as noted later in the flight review (jello).
