Nazgul ECO = Cheaper Nazgul V3?

The ECO makes use of a brand new FC/ESC stack with the extra inexpensive AT32 chip as a substitute of the STM32 F7. I imagine that is the primary purpose why iFlight is ready to supply this drone at such a low worth. As mentioned earlier than on this weblog, the AT32 chip helps to make FPV extra inexpensive, and I feel we’re lastly seeing that pattern take maintain.

Apparently, the default craft title within the Betaflight OSD is “Nazgul V3”, which additional confirms my suspicion that the ECO is simply the V3 with a extra budget-friendly FC/ESC stack. They in all probability simply copied all of the config over and forgot to alter the craft title.

Solder high quality seems top-notch.

Enhancements I Wish to Make

The ExpressLRS receiver is linked to the flight controller by way of a connector. The very first thing I’d do is take away the connector and solder the receiver on to the flight controller. I’ve had a few cases up to now the place comparable connector failed on me, inflicting random failsafe mid-flight. We don’t usually unplug the receiver, so it’s fairly pointless to have the connector, it’s simply asking for bother.

I’ll add my very own GPS to make use of Rescue Mode in Betaflight (just like return to house). Though iFlight provides GPS as an possibility if you buy the drone, it prices $39 extra! I’m not positive what kind of premium GPS they’re utilizing, nevertheless it feels barely overpriced to me. In case you are not afraid of soldering and organising GPS, you possibly can save fairly a bit of cash by doing it your self. I’ve a information explaining easy methods to setup GPS and Rescue Mode: https://oscarliang.com/setup-gps-rescue-mode-betaflight/

The analog digicam “RACECAM” is mediocre. It’s flyable, however the subject of view is kind of small and the publicity adjustments are fairly sluggish when lighting situation adjustments. I’d in all probability improve it to one thing higher just like the Ratel V2: https://oscarliang.com/fpv-camera/#Analog

When you want to enhance vary, it is best to take into account mounting the receiver antenna vertically as defined on this information: https://oscarliang.com/antenna-positioning/

Betaflight Configuration

Closing Ideas

Iflight Nazgul Eco Fpv Drone Bnf Prebuilt 5inch

I completely love the iFlight Nazgul and Evoque collection. They’ve been my go-to pre-built 5″ FPV drones, and now with the Nazgul ECO, it’s much more inexpensive. It’s even cheaper than the “least expensive 5″ FPV drone elements checklist” I put collectively, very spectacular.

Some elements of this drone may present indicators of a finances construct, such because the FPV digicam and lack of GPS, however many of the parts are strong with nice construct high quality, it’s laborious to beat the general worth of the Nazgul ECO.

When you don’t need to construct a drone from scratch and simply need to fly, you possibly can’t go mistaken with this FPV drone. To not point out it’s well-tuned out of the field. Simply slap a GoPro on this factor and you’ll get some fairly superior footage.
