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.

$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!

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 :-\

The EV100 Micro AV Recorder is a DVR for the Eachine EV100 headset. Eachine should have built this into the headset, but here we are. It's about the size of a matchbook and works quite well despite a short learning curve. It's powered by the same battery included with the EV100 and uses the white balance lead. Other than that you can use either of the included 2.5mm to 3.5mm cables to plug it into the video input/output port of the EV100. You can either strap it beside the battery in the headstrap or use the included double sided tape to mount it to the top of the goggles. Vs the Eachine ProDVR This is obviously a repurposed Eachine ProDVR, but it does simplify the design. The ProDVR has different pins for each input and output. In fact the entire side of the unit is dedicated to various keep reading..

Currently on sale for $97, EV100 at Banggood The much anticipated Eachine EV100 headset has finally arrived! Opinions have been quite polarized and unless you've never flown FPV before you're likely to find fault in the field of view (FOV). I've tried a number of headsets and have to admit that I've been spoiled by the FatShark HD2 and HD3 goggles. That being said this is nowhere near that price bracket, so I'd like to compare the EV100 to a few headsets around the same price. Keep in mind that these cost $100 when they were released, so the current $159 price is likely to come down. EV100 vs the Competition I've been a long supporter of the Eachine EV800. It's a great headset for the price (~$55). Feature for feature it's the most comparable headset to the EV100. Both include a keep reading..
