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.

Why 1106 on 3"?

I flew 1407 3" 4S a ton (Rasvelg) because it was nimble and reasonably fast, and then I tried 1407 4" 4S (Garagecrab, Featherlight 4) and it was WAY faster than my 3" rigs and almost as nimble. Then I tried 1103 2" 2S (Babyshark), and it was more nimble than my 1407 3" rigs, but nowhere near as fast. Then I tried 1104 2" 3S (Bullshark), and it was more nimble than my 1407 3" rigs, but not quite as fast. Finally, I tried 1106 3" 3S (Featherlight 3), and it was just as fast as my 1407 3" 4S and definitely more nimble.

This carves out a place in my fleet for a 3" rig again and opened the door for the Splitshark design to be a small, fast, and nimble HD rig.
