Eachine LAL5: Cheap 4K FPV race drone

Eachine LAL5 FPV drone

Like most popular FPV drone brands, Eachine also started to equip their quadcopters with the Cadax TARSIER 4K dual-lens camera. The Eachine LAL5 is build on a robust, orthogonal X-shape carbon fiber frame with 225mm wheelbase. Featuring versatile LAL-F405 flight controller it can be configured with multiple flight modes. 

The 2507 type 1850KV motors are matched with Racerstar 5046 (5″ 3leaf) propellers. The motors are driven by a powerful 50A rated 4-in-1 ESC. The Eachine LAL5 drone can be powered by 4s as well by 6s LIPO batteries – LIHV (high voltage LIPO packs) are also supported.
