Like the BetaFPV HX115 LR, the Happymodel Crux3NLR also comes equipped with a built-in SPI ExpressLRS 2.4GHz receiver. This new radio communication has become extremely popular due to its excellent stability and low latency.

On top of the 115mm, carbon fiber frame has a 18650 battery bay. According to Happymodel, you can have up to 17 minutes of crossing time with a single Sony 18650 VTC6 battery.

The F4 2G4 AIO 5in1 flight controller features integrated 5A ESC, 200mW VTX, and SPI ExpressLRS 2.4GHz radio receiver. The EX1202.5 KV11500 motors are matched with 76mm 2-leaf propellers.

When it comes to long-range FPV flights, an onboard GPS positioning system is a must-have. The Happymodel Mini M8N GPS mode has a 2 meters accuracy and can work with multiple satellites provides.
