Eachine RedDevil “Toothpick” quadcopter

Eachine also has jumped into hype train and released their version of toothpick – RedDevil. It looks very similar to the Happymodel Sailfly-X. This is shouldn’t be surprised as the manufacturer of the most components is the same Happymodel. However, RedDevil has a few differencies. The RedDevil has slightly different design, but the same 105mm size frame. RedDevil‘s canopy is taken from the Trashcan Quadcopter, while Sailfly-X has 3D printed TPU canopy. Both quadcopters have the same CRAZYBEE F4FR PRO V2.1 FC board with 6A 4in1 ESCs. RedDevil’s motors are same Happymodel EX1102 motors, but with slightly bigger KV rating of 8700KV vs SailflyX8500KV

The biggest difference between the RedDevil and Sailfly-X toothpick quads is camera and VTX combo. Sailfly-X has AIO camera with only 25mW VTX and the RedDevil has better Caddx EOS2 camera and 25mW-200mW nano VTX combo.

RedDevil weight is 38g (without battery), slightly more than Sailfly-X35g and thats mainly because of the diferent camera used. 

And lastly – RedDevil comes with a handy bag for carrying the quad and batteries.
