Caddx lately launched the Protos FPV drone package that includes their new digital FPV system, the Ascent. The package appears to be like surprisingly good worth and comes with every little thing you must fly, which initially had me intrigued. I used to be even planning to purchase it for evaluate — however after wanting into the main points a bit extra, I modified my thoughts. Let’s take a more in-depth have a look at what the Protos is, and clarify why I’m not dashing to select one up.

What Is the Caddx Protos Package?
The Caddx Protos is an inexpensive all-in-one FPV drone package priced at $359 – lower than the worth of a pair of excessive finish goggles! It consists of basically every little thing you must get began:
- FPV goggles
- The Protos drone
- Radio controller
- Batteries and charger
Curiously, the drone makes use of Caddx’s new Ascent digital FPV system. It isn’t Walksnail Avatar and it doesn’t match DJI by way of picture high quality, vary, or latency. Nevertheless, it does seem to look noticeably higher than analog.
This drone package is clearly aimed toward novices who desire a easy, plug-and-play approach into FPV. However as I’ll clarify later, there are some compromises.
The place to Purchase
You will get the Caddx Protos package from:
What’s Included within the Caddx Protos bundle:
- FPV field goggles
- Protos micro FPV drone with Ascent VTX
- ExpressLRS radio controller
- USB charger (can cost three batteries without delay)
- Three proprietary batteries
- Equipment (case, cables, battery lead, and so forth.)
The Ascent FPV System
Ascent is a model new digital FPV system. The person interface appears to be like nearly an identical to Walksnail Avatar, however they aren’t associated, and seems to be a totally totally different ecosystem. From the footage out there thus far, picture high quality isn’t higher than Avatar — so primarily based on the low value of the Protos drone, it appears Caddx positioned Ascent as a budget-friendly digital possibility fairly than aiming for high-end efficiency.
If you happen to already personal Walksnail or DJI, there’s presently no compelling purpose to change in my view – it will be a downgrade. Additionally, the utmost VTX energy is simply 100mW proper now, which is okay for indoor whooping or park flying inside line of sight, however fairly limiting for freestyle or longer-range flying.
Fascinating remarks from early testers concerning the Ascent system:
- The way in which it handles low sign is kind of distinctive: when the hyperlink will get weak, the picture shrinks to the middle (“focus mode”). At very low bitrates, it switches to black & white to take care of flyable element.
- Bitrate is comparatively low in comparison with AVatar or DJI — usually round 20–25Mbps.
- Solely 50FPS and 60FPS refresh charges out there. Latency is flyable, however noticeably larger than Avatar/DJI making it difficult to do exact maneuvers.
- Picture high quality is best than analog, however inferior to Avatar, and nowhere near DJI.
The Protos Drone
The Caddx Protos is basically a small cinewhoop fashion drone. Because of the prop guard, it’s comparatively safer for flying in tight areas or round folks in comparison with open-prop micro quads.
Battery & Energy System
It makes use of 40mm propellers and weighs round 62g dry, or about 104g with the battery put in. For reference, that places it in the identical measurement and weight class as BetaFPV Femto. On condition that it additionally runs 1102 motors, I’d count on related ranges of energy and dealing with — enjoyable for cruising, however undoubtedly not a freestyle beast. Nevertheless, the Protos comes with Li-ion battery, not LiPo, so it would have much less punch and energy. Be taught extra about LiPo battery right here: https://oscarliang.com/lipo-battery-guide/
The included batteries are 2S 840 mAh Li-ion packs.
| Li-ion (used right here) | LiPo |
| Larger power density → longer flight time | Extra energy + higher throttle response |
| Lighter for a similar capability | Heavier for a similar capability |
| Decrease present output → weaker punch-out energy | Excessive present output → Higher for freestyle and acro flying |
The battery has a proprietary design— it slides and clip into the drone. It’s handy and beginner-friendly, but it surely additionally locks you into Caddx batteries solely. No Third-party 2S LiPo choices right here.
Anticipate longer flights than an analogous whoop on LiPo, however much less energy when climbing or doing sharp inputs.
Body & Construct
The Protos makes use of a pusher configuration (propellers are mounted the wrong way up). The body is completely plastic, no carbon fibre. The thick shell makes it extra sturdy but in addition a bit heavier than typical interest builds.
One fascinating function: the Protos consists of down-facing LiDAR and optical circulation sensors. These allow Altitude Maintain and Place Maintain modes — good for serving to absolute novices hover with out panic. I’ve seen this idea in BetaFPV’s Cetus drone package just a few years again, personally I’m not a fan of those assisted flight modes for novices, firstly they don’t work that nicely, and so they don’t actually train you the way to fly an FPV drone and practising in a simulator continues to be the most effective place to construct expertise IMO. Happily, if you’re prepared, you’ll be able to swap into Acro mode for correct FPV flying.
Be aware that the VTX has no onboard HD recording, you’ll be able to solely report within the goggles (1080p).
Lastly, the Protos drone doesn’t run Betaflight; it makes use of Caddx’s personal firmware. In case your objective is to study Betaflight, then this drone isn’t the appropriate path.
Ascent Field Goggles
The Ascent goggles seem like a reworked model of the Walksnail Goggles L — very related in form, measurement, options, and so they additionally use 1080p 60hz shows.
Key factors:
- Requires an exterior battery, powered through a barrel plug
- Some customers report gentle leaks, however typical in field goggles
- Inside antennas, no exterior modules or replaceable antennas
- No AV enter, doesn’t help analog
- No HDMI enter, doesn’t help different digital techniques
- Joystick + again button management, acquainted in case you’ve used Walksnail goggles
- OSD doesn’t burn into DVR footage — OSD information is saved in separate file
Radio
The included radio is a gamepad-style controller — compact and primary. It appears to be like considerably like DJI’s distant controller however has ExpressLRS in-built (with an inside antenna).
Nevertheless:
- There’s no show and no EdgeTX interface
- No skill to alter radio settings on the gadget
- Restricted long-term development for pilots who plan to stay with the interest
The excellent news? The Protos drone makes use of an ELRS receiver, so you’ll be able to bind it to any third-party ELRS radio later. In order for you improve concepts, take a look at my suggestions:

Battery and Flight time
The package consists of 3 batteries and a charger.
Battery specs:
- 2S 840 mAh Li-ion packs
- Marketed 8.5 minutes of flight per pack (real-world occasions might range)
These batteries have a proprietary slide-in design, so you need to purchase replacements from Caddx, which locks you into their ecosystem. Sure — with modifications you can run normal 2S packs, however that defeats the simplicity that this package is designed to supply.
The three-bay USB-C charger can cost all three batteries concurrently — much like DJI Open 2’s charging answer.
Who Is This For?
It’s essential to be clear: the Protos is just not a efficiency drone. It’s a beginner-focused FPV coach, designed to get new pilots flying with little setup and minimal technical hurdles. It’s not constructed for freestyle ripping, racing, or long-range.
As a result of it makes use of Li-ion batteries and tiny 1102 motors, energy is proscribed. To not point out Ascent may be very new, and isn’t as succesful as DJI and even Walksnail (and isn’t cross-compatible), you’re shopping for into an ecosystem that has an unsure future.
That stated — in case your objective is just to study the fundamentals of FPV and have enjoyable cruising round a small house, it does precisely that.
Purchase it if…
- You’re brand-new to FPV and desire a full FPV drone package for under $359
- You worth plug-and-play comfort over tinkering
- You intend to fly principally indoors/yard, the place lengthy vary or sign penetration doesn’t matter
Skip it if…
- You already personal Walksnail, DJI, or HDZero. There’s no purpose to change to Ascent at this level.
- You want low latency or good vary/sign penetration
- You need Betaflight configurations (the Protos drone doesn’t use Betaflight however their very own firmware).
- You desire a nimble drone for freestyle or racing.
- You wish to keep away from proprietary batteries.
Conclusion: Would I Purchase It?
The Protos Drone Package
The Protos appears to be a strong newbie coach: straightforward to arrange, sturdy, and surprisingly nicely thought-out. At solely $359, it’s a tempting entry level into digital FPV. However the trade-off is that you simply’re locked into Caddx’s new ecosystem (batteries + FPV system), and the efficiency ceiling is low.
If I had been beginning FPV right now on a decent finances, I’d nonetheless personally select one thing like this with open ecosystem:
With batteries and charger, this setup prices equally to the Protos package, however can be extra future-proof, extra versatile, and arguably extra enjoyable in the long term — particularly in case you plan to develop within the interest.
Nevertheless, judged purely as a plug-and-play newbie bundle, Caddx has executed a fantastic job right here. I simply want it:
- Ran Betaflight
- Used normal LiPo packs
- Supplied extra FPV system choices, e.g. Walksnail, Analog and even DJI O4 Lite.
The Ascent System
Asserting their new Ascent system in a finances drone package is a brilliant transfer — individuals who purchase this are possible novices who’re nonetheless on the fence which FPV system to get, so Caddx has an opportunity to win them early.
However right now, Ascent continues to be in its infancy:
- Just one goggles possibility, a finances field goggles with low specs show
- Just one VTX possibility with restricted 100mW energy, and it’s not even bought individually but
- Wants time to show reliability and neighborhood help
Ascent may enhance over time — and if Caddx expands the lineup with higher goggles, extra VTX choices with higher specs, it may ultimately turn out to be a compelling finances ecosystem. For now I’d move. I have already got DJI and Walksnail, each of which supply higher latency, higher picture high quality, extra {hardware} choice.
