What Makes the BetaFPV Air 5in1 FC Particular?
The BetaFPV Air 5in1 FC is extremely light-weight, making it excellent for the most recent ultralight Air65 and Air75 Tiny Whoops from BetaFPV. In contrast to the earlier 4in1 board, which required a further exterior receiver, the brand new 5in1 FC integrates the receiver straight on the board. This integration simplifies the construct course of, reduces the quantity of wiring, and makes repairs simpler.
Whereas the 5in1 FC doesn’t supply a weight benefit over utilizing the 4in1 FC with an exterior receiver, the general price is $5 much less since you don’t have to purchase a separate receiver. The 5in1 board’s integration is especially interesting for these trying to streamline their builds with out compromising performance.

VTX Energy Testing
Utilizing the ImmersionRC Energy Meter V2, I examined the VTX RF energy output of the BetaFPV Air 5in1 FC. Listed here are the outcomes:
| R1 | R2 | R3 | R4 | R5 | R6 | R7 | R8 | |
| 25mW | 32 | 36 | 43 | 46 | 54 | 59 | 55 | 42 |
| 100mW | 82 | / | / | / | / | / | / | 162 |
| 200mW | 161 | / | / | / | / | / | / | 326 |
| 400mW | 262 | / | / | / | / | / | / | 550 |
For comparability, listed below are the measurements for the earlier Air 4in1 FC:
| R1 | R2 | R3 | R4 | R5 | R6 | R7 | R8 | |
| 25mW | 40 | 38 | 34 | 26 | 26 | 30 | 23 | 20 |
| 100mW | 50 | 80 | ||||||
| 200mW | 85 | 141 | ||||||
| 400mW | 144 | 315 |
There have been considerations in regards to the BetaFPV Air F4 FC having extreme RF energy output at its 25mW setting, which isn’t ideally suited for Tiny Whoop racing occasions with strict RF energy guidelines. It appears the 5in1 FC nonetheless has this problem, however I’ve solely examined one unit, so I can’t verify if this can be a normal drawback.
For these collaborating in races, this may very well be a deal-breaker. It’s necessary to test the RF output of your Air FC earlier than attending a kind of occasions. Nonetheless, for individuals who fly casually at dwelling or with buddies, this shouldn’t be a difficulty. In truth, the 5in1 FC outputs as much as 550mW, which is larger than the 4in1 model, offering higher penetration and vary.
Tiny Whoop Construct
I swapped out the 4in1 FC in my Air65 for the brand new 5in1 FC, and it match completely with none modifications. The digicam and VTX antenna connectors are in the identical areas, guaranteeing that the setup stays unchanged.

Conclusion
The BetaFPV Air 5in1 FC is a superb improve for Tiny Whoop fans who desire a streamlined, built-in answer with out the effort of additional wiring. It supplies all of the core options wanted for high-performance FPV flights in a light-weight, compact type. With the added comfort of an onboard receiver, it’s a superb selection for these trying to simplify their builds whereas nonetheless having fun with top-notch efficiency.
