Numero Uno Martian III

Building my first FPV quad. I started with a randomly chosen Realacc Martian III 190mm/4" kit, but wasn't excited about the bottom mounted battery so I decided to repurpose parts and build to my liking. The pics show both versions.

This one is for fun/backyard ripping on our 4 acres and pond with a bit of friendly makeshift racing with my neighbor too. I've owned and built countless buggies, trucks, fixed wing and heli's, and have been into RC since before LiPo batteries .

 I went for a 4" lightweight build too keep it as light and nimble as possible for reversing direction as I get close to the streams and ponds out back. 

 When selecting parts, the primary influence is that I've never built a FC/gyro controlled vehicle before. I wanted a nimble, mid-level quality machine built from scratch is building and learning these systems is the whole point. I'm also not interested in some of the excessive loss of video signal I'm seeing on YouTube etc, so good quality camera/vtx/antanna was a must. I'll be building pagoda kits from FarView and utilizing my brothers 3d printer for some one-offs.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. 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..
