As winter approaches, it’s whoop season once more! BetaFPV has one thing particular for us — a brand new Air65 II body and cover for his or her standard 65mm Tiny Whoop. The improve guarantees higher efficiency and sturdiness. On paper, it seems like a small replace, however after testing it, I can confidently say this model takes the Air65 to an entire new stage. Let’s dive into what’s modified, the way it performs, and the way it compares to the unique body.

New Air65 II Body and Cover
Left: Unique Air65; Proper: Air65 II
At first look, I used to be somewhat confused why BetaFPV despatched me one other Air65, since I had already reviewed it final 12 months. However upon nearer inspection, I spotted this new model options the up to date Air65 II body and cover. Whereas the adjustments may appear minor at first, they carry some significant enhancements in sturdiness, efficiency, and flight really feel.

Body Design Enhancements
Probably the most noticeable replace is the lowered variety of assist struts beneath every propeller — from six right down to 4. This permits extra unobstructed airflow, enhancing thrust effectivity and general flight efficiency. The ducts are additionally barely narrower, which helps scale back drag and enhance dealing with in ahead flight.
Apparently, regardless of having fewer struts, BetaFPV claims the body is extra sturdy. The remaining helps are positioned extra strategically in high-impact zones, serving to the body take in crash power higher.
In hand, the brand new body feels stiffer than the unique, which probably contributes to the quad’s sharper and extra responsive flight traits. After loads of indoor flights — and the inevitable bumps into partitions and furnishings — I can verify that this body holds up very well. It feels more durable and extra resilient than earlier than.
Weight-wise, the Air65 II body is just about similar to the unique Air65 body (V2 weighs 2.57g vs. V1’s 2.63g — basically no distinction in observe).

A small however considerate design element: the motor mounting pads now embody three raised contact factors simply outdoors the screw holes. This helps forestall the metallic motor screws from scratching your flooring or furnishings throughout indoor flights — a pleasant contact for whoop pilots flying round the home.
Up to date Cover
BetaFPV additionally up to date the cover, and that is an enchancment I actually recognize. The digicam angle adjustment belt on the again has been prolonged, permitting the digicam to tilt decrease than earlier than. This makes an enormous distinction for indoor flying — now you can comfortably fly at slower speeds with a decrease digicam angle, excellent for freshmen or relaxed cruising round tight areas. It makes the Air65 way more pleasurable to fly straight out of the field for slower, extra informal pilots like me.

As of this writing, the BNF Air65 nonetheless ships with the unique body, however you should purchase the brand new Air65 II body individually and swap it your self. Hopefully, BetaFPV will begin together with the up to date body in future batches of the Air65.
The remainder of the {hardware} stays basically similar to the unique model, which I’ll go over briefly beneath.
Restricted Halloween Version
BetaFPV is providing a restricted Halloween version of the Air65 II body — and it glows at nighttime! Merely depart it beneath a lightweight supply for some time, and it’ll take in power to glow at nighttime.
Sadly, BetaFPV informed me this particular glowing body isn’t bought individually; it’s solely out there with the Air65 BNF Halloween Version. In addition they talked about that because of the totally different materials composition, this glow-in-the-dark body is much less strong than the usual Air65 II body. So for those who plan to fly aggressively, it’s greatest to stay with the common model for sturdiness.
To be trustworthy, it’s a enjoyable however considerably gimmicky thought. The glowing impact fades fairly rapidly — after about half-hour, the brightness drops noticeably and turns into barely seen, even in darkness. If you would like constant, shiny lighting in your whoop, you’re nonetheless higher off including RGB LEDs as a substitute.
Flight Controller: The Air 5in1 FC
On this Air65, it continues to make use of the identical Air 5in1 flight controller. Because the title suggests, it integrates the flight controller (FC), ESC, ExpressLRS receiver, video transmitter (VTX), and on-screen show (OSD) right into a single compact board. This design saves weight and simplifies wiring — ultimate for tiny whoops the place each gram counts.
There’s no USB-C port on the FC itself. As an alternative, BetaFPV features a USB adapter cable that you simply use to attach the board to your laptop. It’s a minor inconvenience, however a good compromise for preserving the board light-weight.
The ESC runs Bluejay firmware at 96kHz PWM frequency, which improves motor effectivity and makes throttle response smoother and quieter. If you happen to desire stronger braking and snappier throttle response, you may re-flash to 48kHz, however understand that doing so can scale back flight time noticeably.
One other noteworthy element: the motors are soldered on to the FC as a substitute of utilizing plug connectors. Whereas that makes repairs barely much less beginner-friendly, it’s a great design selection. Direct soldering lowers electrical resistance, improves energy supply, and saves a small however significant quantity of weight. And realistically, motor failures on whoops are fairly uncommon, so it’s not one thing most pilots should fear about typically.
VTX and Digital camera Setup
The built-in VTX helps output energy from 25mW as much as 400mW, adjustable in Betaflight OSD menu. For indoor flying, I discovered 25mW to be completely adequate — larger energy isn’t all the time higher except you want extra penetration or vary. The truth is, working larger energy indoors could cause the VTX to overheat and drain your battery quicker.
The light-weight dipole antenna performs surprisingly nicely for short-range flights. Whilst you may improve to a round polarized antenna for improved penetration, I’d argue it’s pointless for an indoor whoop — each further gram counts right here. The antenna connects through a U.FL connector, making it straightforward to improve, or exchange if it will get broken.
If you happen to expertise video interference from your own home WiFi, attempt switching to a Raceband channel that’s farther out of your router’s frequency — Raceband 8 (R8) is a good choice for a cleaner sign. Be taught extra in my FPV channel information:
The C03 digicam delivers clear analog video. It’s nothing groundbreaking, however it’s completely succesful for freestyle and racing observe.
Flight Efficiency and Sturdiness
On paper, the Air65 II’s new body design sounds promising — however does it make a noticeable distinction in flight? I flew the brand new Air65 II and the unique Air65 back-to-back, and actually, the distinction wasn’t big. Maybe the brand new model felt barely extra responsive and snappier — although that is also as a result of my older Air65 has seen over 100 flights and the motors aren’t in the perfect situations.
One factor I did discover, nonetheless, is the elevated body rigidity. If you twist the brand new body by hand, it feels stiffer with much less flex. Within the air, this interprets to a firmer response and sharper management really feel. It’s doable that BetaFPV tweaked the fabric combine or body geometry to enhance structural stiffness. A stiffer body may produce cleaner gyro knowledge that helps PID tuning.
That stated, the development isn’t dramatic — most pilots probably wouldn’t discover except flying each variations back-to-back.
With a 1S 300mAh LiHV battery, you may count on round 4 minutes of flight time, relying on how arduous you push it — fairly typical for a 1S 65mm whoop.
After about 20 packs of indoor flying (and loads of crashes into partitions, doorways, and furnishings), my Air65 II body remains to be holding up completely. In comparison with my older Air65, which began to point out seen scuff marks and minor duct deformation, the Air65 II stays in noticeably higher situation.
Out of the field, the tune from BetaFPV is great — easy, locked-in, and responsive. It handles sharp turns easily, throttle management feels clear, and there’s no noticeable oscillation or jello. That stated, I believe there’s nonetheless some room to fine-tune it additional. Would you wish to see my customized PID and filter tune for the Air65 II? Let me know within the feedback beneath — I’d be completely happy to share it.
Enhancements
If you happen to’re trying to squeeze a bit extra efficiency out of your Air65 II, listed here are just a few easy upgrades value making an attempt.
First, take into account changing the inventory metallic motor screws with PEEK screws (m1.4). They’re lighter and have a decrease tendency to come back free throughout flight. Get them right here:
There are additionally just a few small areas the place you may trim pointless plastic or materials to avoid wasting weight:
Take away the “arrows” on the body Trim any extra warmth shrink on the VTX antenna.
These tiny tweaks shaved off round 0.7g from my construct, lowering the full weight from 17.3g right down to 16.6g. That may not sound like a lot, however it’s a few 5% discount — and in a tiny 1S whoop, that’s sufficient to note enhancements in flight time, throttle response, and agility.
Battery Ideas and Charging Recommendation
Correct battery care is vital to getting constant efficiency and lengthy lifespan out of your 1S packs. Listed below are my suggestions:
Keep away from discharging beneath 3.0V throughout flight. Land earlier than it hits 3.2V per cell, after touchdown, the voltage ought to recuperate to round 3.6–3.7V. For security, it’s really helpful to cost at 1C (0.3A). If you happen to resolve to cost at quicker charges, ensure that to observe battery temperature commonly for security. If you happen to received’t be flying for greater than per week, retailer your LiPos at 3.8–3.85V per cell to delay battery life.
I like to recommend utilizing a devoted 1S charger with storage mode, such because the Vifly WhoopStor V3 or GEPRC WooPower. Each are compact, straightforward to make use of, and feature-packed 1S battery chargers.
The right way to Setup
Firmware:
The FC comes with Betaflight 4.5.0, and the FC goal is BETAFPVG473. Yow will discover the default CLI diff right here. ELRS Receiver: BETAFPV 2.4GHz AIO RX ExpressLRS firmware model 3.5.6 ESC: A-X-5 – Bluejay, 0.19, 96kHz
Firstly, bind the receiver, observe this information for those who don’t understand how:
Listed below are the Betaflight configurations:
Load ExpressLRS Preset Set Your Charges Allow Telemetry Set Arm swap, angle mode swap, turtle mode swap Set OSD (disable “Core Temperature” beneath warnings) Scale back present sensor scale to 660 for extra correct mah studying (would possibly want additional adjustment).
Conclusion – Ought to You Get the Air65 II (or the New Body)?
The BetaFPV Air65 was my favourite whoop of 2024, and with the brand new Air65 II body, I can confidently say it stays my favourite going into 2025. It’s one of the well-balanced whoops out there immediately — providing a superb mixture of energy, effectivity, construct high quality, and tuning proper out of the field.
Whereas the Air65 II doesn’t look drastically totally different from final 12 months’s model, the refinements add up. The body is stiffer, extra sturdy, and the brand new cover design permits for a decrease digicam angle, making it extra pleasurable for freshmen or anybody who prefers slower, extra relaxed flights indoors.
That stated, the efficiency enhancements are refined in real-world flying. If you happen to already personal the unique Air65, there’s no pressing must improve. However for those who’re out there for a brand new whoop, or planning to switch the body, the Air65 II body is totally value getting — it’s a refined evolution of among the finest 65mm whoops you should buy.
