Simple, Effective MOds for the Sailfly-x and Red Devil

The good and bad of the Sailfly-X and Red Devil
Happymodel have launched two of the better value toothpicks recently of which I have reviewed both - the Happymodel Sailfly and the Eachine Red Devil. Unfortunately both have minor niggles on the FPV side of things -

• The Happymodel Sailfly-x is low on vtx power (25mw only) and the although good for an AIO camera/vtx it it has comparatively poor dynamic range. Also, you need to change canopy if you want to change camera angle

• The Eachine Red Devil (made by Happymodel) has a better VTX which goes up to 200mW, a better camera in the Caddx EOS2 but the canopy is plagued by Jello and the camera is terrible at handling the image in low light conditions with peculiar red hues showing up at odd times.

The objective of the mods:
Since the underlying powertrain of these quads is light and effective I set out to improve the above issues while trying to stay as light as possible. Also, in order to keep things simple I wanted to avoid soldering where possible to provide an easy and cost effective upgrade path for those who wanted to emulate the build. The result? I'm super pleased:

Modded version weighs just under 39g

Sailfly-x minus 3d printed battery holder (plus rubber band) is just over 38g

Eachine Red Devil is closer to 39g with battery holder

LArva-x is quite a bit heavier due to slightly bigger motors, heavier frame and dvr on board
