Featherlight 3"

Featherlight is shipping now at PitchRollYaw! Buy the bundle and get the frame AT COST, or get the frame by itself at full price. All kits ship with 5 arms, and note that the final version has pressnuts instead of locknuts for easier arm changes!

With most 3" builds -- including mine -- using 1407 motors that are clearly better suited for 4" props, I've decided to try something different to see if new life can be breathed into the 3" platform.

The idea is simple: Build a featherlight 3" with based around 1106 6000kV motors and 3S batteries. The result should be an incredibly light build that's nimble, quiet, and fast as hell.

With an all up weight of 150g with a 650mAh battery, this build ends up with a 9.5:1 thrust to weight ratio.

I'm really interested in seeing this come together. Would love to see video once it's done!

I posted some links in another comment if you're still interested in seeing some footage. It looks super fun!

Now the big question, how does it fly? Need to see some DVR.

We'll see when my replacement motors come in... One of the iPOWER 1106s was DOA :-\

Just to follow up ...

lazd's SF City Ripper video also features the featherlight 3" at some points, alongside a bunch of other quads. See 0:24, 1:11, 1:37, 1:58:

lazd, maybe include these video links in the main description? ;-)

$275 AUD to get the bundle, shipped to Aus - so damn tempted! I'm also wanting to build a 2" quad. Ugh so much stuff and not enough money!

At last, the Topsky F7X V2 is available. This is the updated V2 release which came 3 months after the failed V1 model from October, 2017. V1 had several issues and most reviewers declared it an utter failure. Did Topsky fix the issues and are these worth buying? Let's find out. On paper this sounded like a wonderful new goggle. Unfortunately we were let down. The displays exhibited ghosting, the..

The ThinkTank FPV Airport Helipak is the premier travel bag for FPV enthusiasts. I've taken this bag across the country and around the world, and I really can't imagine a better pack for the job. It's huge. It's the size of a carry-on luggage, and it's designed specifically for FPV. It offers customizable compartments that can store a handful of quads, a transmitter or two, a couple sets of goggles,..
