Looks amazing. How would this compare to the original GepRC Phantom? And what flight times do you get at 450 or 650 mAh?

thanks for the comment!

i have never flown factory phantom so no way to compare. also this was a winter build so no outside flytime yet just basement hovering. get 6+ minutes hover time, though for actual hard flying i only require 3 minutes

battery - i did consider 450mah but for only ~2g more the 650mah made sense.

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. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
