The Eachine Shadow Fiend is a lightweight 4 inch quadcopter designed for long range flights. This version I have reviewed comes with the CADDX vista which is for the DJI HD FPV system. It is also available with the CADDX Nebula and analogue versions.
Like with all products they make, the Eachine brand is never the first to invent or innovate a category but they are more of a "me too brand" where they look to provide a comparable product to the market leader at a lower price. I'll be very clear here and say that Eachine is a brand only and not a manufacturer. Thus they can have very good products and very poor product depending on which manufacturer is used. Make no mistake though, this category was made possible by the development work completed by Dave C and then picked up with his blessing by Flywoo. Check out Dave C's excellent channel Youtube, I have been a long time fan.
The Eachine Shadow Fiend is a 4 in long range lightweight quadcopter designed for endurance and effciciency rather than power for racing or freestyle and is heavily inspired but the Flywoo Explorer 4 LR, the Iflight Chimaera LR 4 and the Diatone Roma F4. All are based around a lightweight deadcat or squashed x frame, lightweight electronics, efficient 1404 motors that range from 2750 - 3500kv with lightweight 4 inch biblade props. Additionally all are available in digital FPV and analogue versions as you can see below:
At time of writing I have a 15% discount code for the digital versions of the Eachine Shadow Fiend 4" LR for the first 15 people making the Nebula version $238 and the Vista version $255 - only $100 more that the Vista itself. Code and links in the conclusion at the end.
I think this is a wonderful category because long range flight was previously limited by large, heavy and expensive 7 inch rigs which although lovely to fly, can be very expensive to lose on a failed long range run. Yes these smaller rigs are more susceptible to wind more than their larger and more powerful brothers but the lower cost and the bind and fly nature of these 4 inch version has popularized this area of FPV that was previously a little mysterious and hard to attain.
