This is the newest freestyle rig that I've added to my fleet. After spending the last 15 months exclusively flying X-Hover Stingy Frames with Betaflight based flight controllers, I've decided to try something as different from my standard builds as I could come up with while suiting my typical freestyle needs.
While everyone is migrating over from 4S to 6S, I decided to commit to a 5S powered route for all my quads because I also fly quite a few 6" quads. Since the 6" quad space is a relatively unpopular one, I've had a hard time locating a good, smooth, low-kv motor (1400kv) that matches a 6" / 6S setup.
In my opinion, 5S is able to keep the same rough consistency in power output as 6S is. The difference between 5S to 6S is far less dramatic than the difference between 5S and 4S.
The goal of this quad was to build a relativey lightweight (for freestyle) and reliable 5S powered rig that is high kv in power, long freestyle flight time, and has excellent flight characteristics.
In order to achieve this, I've dropped the Reverb frame height from 30mm down to 25mm with aftermarket standoffs (for a lower center of gravity), selected the incredibly smooth and powerful 2407 sized ETHiX Konasty 2200kv motors and paired them with the extremely battery efficient ETHiX 5x3.1x3 S3 prop.
I've used the following method below for shaving weight off the typical Reverb Build:
Average 5S powered Reverb / Kiss V2 AUW: 665g-680g
My current 5S AUW: 621g
With ThunderPowerRC's 1300mah 4S AUW: 585g
With a "relatively" light 621g AUW, low cg, heaps of power, crystal clear FPV feed, and KISS V2 firmware, this freestyle quad is incredibly smooth and responsive. Kiss firmware (my first Kiss build) appears to have slightly less stick latency than even my best tuned 5" Betaflight quad and generally feels a bit more locked in and predictable from my intial tests. The Rotor Riot Micro Eagle Pro FPV cam (with gain dialed down to zero) is definitely a fantastic successor to the fullsized CCD based Swift 2. And finally, the 2407 2200kv Konasty motors (which TBH are highly inefficient above 80% throttle) are highly responsive and efficient from 20-70% throttle (where most freestyle pilots sit).
I may decide to change these motors in the future to a lower kv (2000kv to 2050kv) but for now, I'm happy with the heaps of power, predictablity, and 4 minute flight times.

where did you get the fpv cam mount?
This is probably the coolest Reverb I have ever seen. You did an amazing job building it, as well as this RotorBuilds page. Great work!
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..

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..

This is excellent! Everything from the actual quad to the build guide and images. This is how every build guide should be executed.
Made me want to rebuild my Reverb.
