On this assessment, I’ll be taking a detailed have a look at the BetaFPV Air75, a 75mm tiny whoop that guarantees light-weight and spectacular flight capabilities. I’ll share my private experiences with this quad, highlighting its strengths, areas for enchancment, and the way it stacks up towards the favored Mobula7.

First Impressions
For $95, the {hardware} high quality and worth of the BetaFPV Air75 are spectacular.
The Air75 is mainly an even bigger model of the Air65 we not too long ago evaluations, with bigger props and motors: https://oscarliang.com/betafpv-air65/. Nonetheless the flight traits are very totally different.
The BetaFPV Air75 weighs simply 21g, practically 4 grams lighter than its predecessor, the Meteor75. With a 1S 450mAh LiPo, the burden involves 33.5g, and with a 1S 550mAh battery, it’s 35.2g. For comparability, the Mobula7 1S Tiny Whoop weighs 24g with out battery.
It’s extremely gentle—about the identical as a 65mm whoop from two years in the past. Don’t underestimate the distinction a number of grams could make; it considerably impacts effectivity and flight traits for small quads on this weight class.
This weight financial savings primarily comes from the upgraded 75mm body, which shares the identical design because the Air65 however is barely bigger to accommodate the 40mm bi-blade propellers from Gemfan and the 0802 23000KV motors.
The remainder of the electronics are equivalent to the Air65, together with the 4in1 Air AIO FC, an exterior ExpressLRS receiver, and the C03 FPV digicam. The digicam even features a piece of black tape on the again of the PCB to forestall gentle leakage.
The U form battery connector is resembling good contact, no extra struggling when connecting the battery.
Motor and Cover Design
The Air75 options highly effective 23000KV motors, that are extremely highly effective for this construct. The diminished weight not solely enhances maneuverability but in addition minimizes affect throughout crashes, resulting in elevated sturdiness.
Nonetheless, just like the Air65, the digicam tilt angle is a tad too excessive for indoor flying, even at its lowest setting. I want BetaFPV had included extra adjustment factors for the digicam angle on the cover. The present angle is adjustable between 25 and 35 levels, which is ok for outside flying, however for indoor use, it’s a bit an excessive amount of—15 levels can be ultimate, particularly for inexperienced persons.
You possibly can, nevertheless, use the identical modification I did with the Air65 to decrease the lean angle.
Picture and VTX Efficiency
The digicam within the Air75 delivers superior picture high quality in comparison with the Mobula7. The footage beneath speaks for itself.
The VTX efficiency is one other spotlight. At 100mW, it offered constant efficiency, even when flying outside inside 100 meters by means of timber and bushes. For indoor use, 25mW was greater than sufficient. I didn’t want to make use of the utmost 400mW energy setting throughout my testing. This dependable video sign is essential for an pleasurable FPV expertise.
Nonetheless, word that the 25mW setting on the VTX outputs greater than 25mW, which could possibly be a problem for tiny whoop racing occasions with strict guidelines about energy output. BetaFPV has acknowledged this and promised to handle it in future batches. They may ship me a brand new FC this month to substantiate in the event that they’ve fastened the VTX output subject.
Connecting to Betaflight requires the USB adapter which is offered.
Flight Efficiency
The BetaFPV Air75 is palms down the most effective 75mm tiny whoop I’ve flown to this point. It flies impressively effectively proper out of the field. Though the PID/filter tuning nonetheless has room for enchancment, as with the Air65, it’s fairly good total.
Not solely is it highly effective, but it surely’s additionally extremely nimble. Flying the Air75 and Mobula7 again to again, the distinction in flight traits is noticeable, and it makes you respect the burden discount. With a 1S 450mAh battery, the Air75 hovers at 31% throttle (absolutely charged), and with a 1S 550mAh battery, it hovers at 33% throttle. You barely want greater than 50-55% throttle when flying indoors—it zooms round like a rocket.
One other standout function is the spectacular flight time. On a 1S 450mAh battery, I constantly bought about 5:30 to six minutes of flight time, whereas on a 1S 550mAh battery, I used to be getting virtually 7 minutes! For comparability, the Mobula7 solely offers me about 4:30. That is largely because of the light-weight design, which considerably improves effectivity.
Initially, I had issues concerning the 23000KV motors, on condition that its predecessor used 19000KV motors. Nonetheless, these motors carried out admirably, offering loads of energy and responsiveness with out sacrificing flight time.
Air65 or Air75?
The choice is straightforward: In the event you primarily fly indoors, go for the Air65. In the event you largely fly outside, the Air75 is the higher alternative.
The bigger 75mm whoop is extra steady outside and handles breezes higher. The elevated platform dimension and momentum additionally make it extra enjoyable to fly in freestyle and acro mode. Nonetheless, it’s so quick that it’s tougher to regulate exactly in tight areas in comparison with the Air65.
Conclusion
General, the BetaFPV Air75 is an excellent 75mm BNF tiny whoop. Its light-weight design, spectacular flight time, and strong efficiency make it a best choice for each inexperienced persons and skilled pilots. For $95, it’s onerous to discover a higher choice on this class, and I extremely suggest it to anybody on the lookout for a 1S 75mm whoop.
