HGLRC Omnibus F438, 33A 4 in 1 ESC & Switchable vTx Stack

The XJB F438 setup is an upgraded flight controller stack from HGLRC which now has a 33A 4 in 1 blheli_s esc supporting bursts up to 38A. Both the F4 flight controller and the switchable video transmitter have been upgraded to v2 but the total overall weight of the boards is still less than 12 grams! This is an amazing and very convenient stack for 65-250mm drones. The included four-in-one ESC is often quoted as being a 38 amp unit but please note that is the burst current support, not the continuous! We would consider this an upgrade to the previous F428 and now use it for our Air-Ro builds. There is also an F440 which has the 40 amp DinoShot escs.

Please test using the USB port prior to soldering as soldered boards cannot be accepted for return.

Included: -

• 1 x Micro F4 AIO Flight Controller with BEC and OSD
• 1 × 33A blheli_s 4 in 1 ESC for brushless motors
• 1 × 48 channel 25/100/200/350mW switchable vTx
• 1 x Capacitor
• 1 x Antenna
• 1 x Bag of screws

The top of the stack has the switchable 48-channel video transmitter with a wide input voltage range accepted. The middle board is the F4 flight controller and the bottom layer is the esc board. The solder pads on the ESC stick out from beneath the flight controller for relatively easy in-situ access should that be absolutely necessary. The firmware is blheli_s and so Dshot600 is supported.
