Update: I've replaced the diversity receiver with a micro v2 and made a TPU tail to hold the antennas in a better position

last test: 20min with Hero7 onboard on 6s1p 4000mAh (Samsung 40T 21600)
first test: 27min on a 6s1p Lion pack (Sony VTC6) -

car chasing with LiIon (read video description):

reelsteadygo test done on this frame:

big motor issue: contact surface with the propeler is flat and has no friction which combined with the fact that the nuts are low profile is the perfect formula for props coming off (untightening) mid flight. this is unacceptable for such a large motor which can spin 7inch props. V2 solved the issue.

frame issues you should know about:

  • 15mm standoffs are joke, had to replace them with 25mm ones.
  • captive nuts are not preinstalled as they should

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays.
