2021 ExpressLRS Stretch X Racer

By Werdna FPV on Jul 05, 2021

Some highlights of this build:
-ExpressLRS 2.4 running 500Hz for extra low latency yet robust link
-96khz PWM Airbot 50A ESC, full size mosfets on a 20x20 stack
-HQ R35 props on 1950kv, my first time trying high kv low pitch props
-Decently low weight for a stretch X quad (275 grams w/o LiPo)
-Kevlar tape over motor wires (suggestion by my friend DzFPV)

I'll eventually be changing this frame over to a Reduxair Raven/Five33 Longback and doing a comparison between it and my True X Switchbacks!

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class!

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
