Ez-wifibroadcast DIY HD FPV system based on ov5647 camera, Raspberry Pi Zero and high power AR9271 transmitter.
Will be running ardupilot on onmibus F4 V5, note the V5 has no built-in current sensor, hence 4in1 esc with current sense.
Expected runtime:+20min flight time on 160g 25c 2200mAh 3s zippy compacts (AUW 555g)
or +35min on 330g 5400mAh 3s2p Li-Ions (AUW 710g, similar to mavic)
XL8 arms modified to accept triangle bolt pattern.
Mini GPS replaced with BN880 M8N, as noise from nearby regulators made it unusable.
First tests
Zippy Compact 25c 2200mAh 3s
17minutes hover at 6A consumed 1600mAh (72% of 2200mAh).
Motors consumed an average of 64W (5.5A at 11.6V), efficiency 8.6 gramms per watt.
Other loads (Raspberry Pi, VTX etc.) 0.5A
BS-430 ESC current calibration result (calibrated at 6A):
BATT_AMP_OFFSET: -0.013
BATT_AMP_PERVLT: 25.639
Omnibus F4 V5 Vbat calibration result:
BATT_VOLT_MULT: 10.937

150 meters isn't even as far as a 200mw vtx will get you... I'm thinking that's more like 25mw type range

Not using the RC functionality of ez-wifibroadcast yet, for that im still using trusty old openlrs https://openlrsng.org
How have you found flying with the raspberry pi camera? I ran a raspberry pi camera setup for a while, but with the analogue video out fed into a 5.8vtx. It was a wierd experience too much delay and the camera seemed effceted quite badly with the vibrations from the quad. Never got used to it so shelved the idea. This build has sparked my interest again cheers. Like the OSD.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
