BetaFPV X-Knight 35 FPV drone with ExpressLRS

BetaFPV X-Knight 35

BetaFPV just released their second FPV drone with an onboard ExpressLRS receiver. This new radio link uses LoRa modulation and provides a faster response rate and lower latency over long distances. The BetaFPV X-Knight 35 drone has a wheelbase of 155mm and weighs only 147 grams without a battery.

BetaFPV X-Knight 35 adopts an F4 AIO flight controller with integrated 20A ESC. The FC has 3 full UARTs and an 8M flash chip for Blackbox. Its lightweight 1404 3800KV Brushless Motors are matched with 3-leaf 3.5″ propellers (HQ 3520 or Gemfan 3520).

The X-Knight 35 can be powered with 4S batteries. BetaFPV suggests using 650mAh–1100mAh LIPO packs. With a 4S/750mAh battery, you can expect about 5-6 minutes of flight time when you are freestyling or up to 11 minutes when you just cruising.

Adopting Caddx Polar Vista kit, the X-Knight 35 is suitable for day and night flights.
