Pros
- Well equipped 3 inch FPV racer.
- Helifar F4 flight control board loaded with Betaflight OmnibusF4 3.2.4
- 600TVL CCD camera provides very sharp and colorful FPV video feed.
- 48 channel OSD switchable FPV transmitter with varied power levels 0/25/100/200/400/600mW.
- Skystar ST1408 3800KV motors.
- BLHeli32 25A/30A 4in1 ESC
- On screen display (OSD) with menu options for PID tuning, FPV transmitter control, etc...
- Beeper and lightbar.
- 2 to 4S capability, now with installed XT30 connector (original version had XT60).
- Available BNF (Frsky and Flysky), and PNP
Cons
- Stock PIDs seem a bit sloppy and could use tuning. AndyRC has reviewed and tuned this drone, providing his PID tuning here . He also suggests alternative Gemfan 3052 propellers to provide more "oomph" to the drone.
- Frsky version receiver doers not have RSSI capable firmare. Here's how to flash such to the receiver if you desire such
- Although the transmitter is capable of 400 and 600mW transmission power, I do not recommend using such. The bottom face of the transmitter does not have good ventillation, and may cause overheat/failure of the transmitter.
