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.

  1. Please help me….I did a reset after doing something that disabled my arm switch. I could not figure out what I did so I thought I’ll reset and it will just change my PIDs channel map and so on. Well it reset everything, including the ports tab, and my dumb self did not diff all. And have no clue how the ports tab is supposed to be configured I have tried about everything there is to do and cannot figure it out. Is there any way you guys could get your hands on a CLI dump for the LAL5 drone. I have searched hi and low emailed Eachine and BG with no luck.
    Please help
