In November 2022. hottest things in FPV are Walksnail Avatar digital system, ELRS Radio link and upcoming 4.4 BTF version RTH land function.
The best way to learn and test new things is to make a build around them. :)

This is 7'' Mid/Long range build and also it is my transition from analog to digital system and from FrSky to ELRS radio link.
Digital system will be Avatar micro plus VRX use with analog SkyZone 03O goggles.
For ELRS I will flash FrSky Taranis xQ7 radio with EdgeTX firmware and
will use Namnino 2.4 Ghz Tx JR Module and Reciver.


The frame I will use is FlyWoo Mr. Croc.
After reasearch on Web and facebook groups I choose to go whit basic build setup, 50A+ ESC and 2806 1300kv motor size.
One thing I like to do in my builds is to try combine components of the same brand together so for this build I I choose
Tmotor combo, F7 pro FC + 55A ESC and F90 2806.5 1300kv motors.
For GPS module unit will use Flywoo Goko combining it whit frame brand.

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

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

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..
