Eachine Lal5 5" 4K HD REview Part 1: Specs and BEtaflight RPM filter setup

Eachine Lal 5 FPV quad

Introduction and spec

The Eachine Lal5 is a new 5" freestyle quadcopter from Eachine. It's most notable features are the new Caddx Tarsier V2 camera system that offers a high quality analogue feed and up to 4k HD recording. Also worth pointing out is the impressively specced powertrain - high quality 2507 1850kV motors that look like they are made by the same OEM as flywoo. These are the biggest motors I've seen on a 5 inch quad before. Further details on specs:

• 225mm true x frame with 5mm thick arms
• 2507 1850kv motors (1750g max thrust)
• F4 flight controller with bluetooth control, 6 UARTs, barometer, 5V and 10V BEC
• 50A BLHeli_32 ESC 3-6s
• Caddx Tarsier V2 cam with 4k HD recording and ND8 filter
• Eachine TX805 25-800mw VTX
• RHCP antenna
• Dalprop T5046c v2 cyclone props

Build quality and component choice discussion

Electronics: Looking more closely at the electronics build it seems to be fairly well thought out. The primary stack contains the 50A BLHeli_32 esc, f4 flight controller and the TX805 VTX (my favourite budget vtx as reviewed here). Looking a little closer at the flight controller it actually has a barometer (for accurate altitude readings and bluetooth for connection via speedybee app. It also has a 10v rail for super clean video much life the Airbot Omibus F4 V6 which I love. Behind this there is a separate 20mm stack that holds the 2 boards that run the Caddx Tarsier v2. Aluminium standoffs are 30mm high so definitely not a low rider but the advantage is plenty of room to fit the stack with good spacing. The ESC has a 35v 470microfarad capacitor that should help manage voltage spikes and keep video clean and up front is the dual lens tarsier camera unit. Included is their ND8 filter which is a nice touch. The TPU 3d printed camera mount does a good job of bringing the camera forward to minimise props in view but still protects that camera well. Print quality is the best I have ever seen. Antenna is well integrated with the TPU mount but I fear signal will be blocked by the battery when flying towards myself - something I must test for sure. There is no receiver included but there is a loom pre-wired to 5v, ground and sbus for a frsky receiver. All pictures below can be embiggened
