VXS: The 135.6 MPH Ugly Duckling

VXS - The S doesn't stand for sexy

Hit 135.6MPH today with a 5s... and a little help from the wind. Speed was disappointing since there was a lot of help from the wind. Blackbox revealed that only 78% power was being utilized due to a misaligned motor (see project page: https://downanddirtydrones.com/portfolio/vxs/ ) Not only that, PIDs are a bit off.

This is the Stretch version of the VX1. The head on this one is definitely not pretty, but I did what I could to protect the FC. As long as it does the job, I'm happy. Looks like a giant mosquito from The Lost World. This will probably end up being my favorite quad in the fleet since it is optimized for general flying/racing.

One nice thing about this frame is that a Mobius mini can be strapped to the back without having a detrimental effect on the cross section.

ONCE AGAIN - I managed to get HORRIBLE video. At least it's on Mobius Mini which was set at a bad angle. At least it can be easily fixed for next time around.

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..
