Featherlight 3"

The Falcon Multirotors Featherlight is undergoing a final round of revisions and will be available for purchase in early September!

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.

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 :-\

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