While everyone is Jumping on the Micro Band Wagon, I decided to build a 3S-4S powered micro quad. Most of the micro quads are pretty generic. They maybe fast, some are strong, hell even some are extreme in their quality of the build. The issue is money. Most of the industry is changing and profits mean more than quality. I am not apposed to them making money, but the money made is lacking in real innovation, quality, and correctness for the purpose.

Goal and Parts Selection

The goal of this Micro freestyle build is to make a reliable 3S-4S powered rig with a high KV motor, long freestyle flight time and has excellent flight characteristics.

Weight Reduction

I've used the following method below for shaving weight off the typical micro Build:

Micro FPV Cam over Full-sized FPV Cam
TBS Crossfire NanoRx instead of the Frsky
TBS Unify Pro V3
TBS Micro receiver antenna
I minimized the use of zip ties and shortened wires to the appropriate working length.
I Used the Tattu 450mah Lipo, It's by far the lightest 3S and 4S batteries made to date of this size.
1206 Xing Motors instead of Mamba motors

I installed a TBS Triumph Pro micro antenna for range and strength
Custom TPU antenna mount
TBS NanoRx for range
RunCam Swift for quality in all lighting
Mamba F722 mini flight controller stack for speed, options, future proof, and capable of 6S at 30 amps for plenty of head room in the electronics.
35v 330ul Panasonic capacitor for clean video and clean power to electrical components
1940 Gemfan Hulkie Props
Standard buzzer to help find
Custom CLI programing in BetaFlight to have a specific tune and throttle used automatically selected based on cell count ( total voltage) of battery used.

The AUW is 122 grams with a 3S 450ma battery


With a 122g AUW, heaps of power, crystal clear FPV feed, and Betaflight 4.1 firmware, this freestyle quad is incredibly smooth and responsive. The build feels locked in and predictable from my initial flights as a newbie. The Swift is a fantastic FPV cam and allows many adjustments. And finally, the XING 1206 6500KV motors are highly responsive and efficient throughout the rpm band. The native ability of 3S is very fast at 60mph and with a small throttle limit (automatically selected by voltage in BF), the 4S tune hits 65mph+ even faster. The F722 FC allows it to be very versatile with a lot of processing power and 32-bit action. It has awesome range, clean video feed, and the receiver goes forever. The electroplated body and prop combination allows it to be seen easily and it looks great.

Maybe add some LEDs and try 2040 props

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..
