Didn't really care much for the Acro performance (TWR) of a 2" outdoors so I recently rebuilt my 2" Whirlygig into a 3" (https://rotorbuilds.com/build/19157)
This little Tri is uses Betaflight 4.1.1 and its "fancy" motor-filtering to provide superior handling.

Specs
Build weight 37 grams only camera but 54 grams with 2S 300mAh LiPo attached.
Note: Picture showing the scale is the same Tri but with the older 2" props. (Weights the same though)
Hover time 8:45 (confirmed)
Acro time 3:50 (confirmed)

Video
Updated 3/28/2020 with Nano Whirlygig's 1st spring flight. (man am I out of practice)

awesome! it looks like it flies great!

My son (8 years) made a iPhone video of the nano tri earlier today. Came out pretty good despite the very obvious prop wash.. The copter was flown at 30% throttle scaling to make it more manageable for my son learning to fly Acro.

When i have chance I'll post it on Youtube and post the link.

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. 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..
