Varvatus Vex v2.0 - MidRange 5'' Freestyler

Hi guys,

this is the updated version of the previous VarvatusVex v1.0 build.
After some time and practice, it is normal to need more features and more performance.
This version is really funny to fly with, fast and aggressive, with a very good range and 4-5 minutes of hard flight with the Turnigy Graphene 1600mah 75C.

The first limit of the previous version was the 3D printed PETG frame. It was a good starting point, but it is not even comparable with the solidity and the reduction in term of vibrations that can be achieved with a carbon fiber frame. Every crash with a plastic frame meant a full rebuild of the drone that was quite tedious. I will never turn back. Now this quad have a TBS Source One Frame... and it is simply awesome...

Another important improvement regards the range, as this version relies on the Taranis and R9M - R9MM system. The better radio coupled with the R9M, allows to extend significantly the range of the flights to many kilometers (tested 3km easy). For this reason should be considered at least a mid-range drone.

The new FPV camera (Caddx Turbo Micro F2) allows to have really clean images, even in dark situations. The results with this camera were better than expected. Also the VTX was improved with a more recent version (TX805). Goggles in my gear set are FastShark HDO2.

Last but not least, it has a double layer of silicone conformal coating, that makes it water resistant!!

Hope you can like it!

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
