FPV videos

I have been flying a lot of FPV quadcopters this summer. In the spring I got the DJI digital FPV system. I previously used Echine EV800 box-goggles, and of course, it was a big difference. Not only is the image quality on a whole other level, the goggles themself are a lot more comfortable to where and use. This upgrade made FPV flying a lot more fun. I have been flying and training a lot. Trying to learn different freestyle moves and also flying through gates and hitting smooth resing lines. But chasing other drones and airplanes is probably what I find most interesting. Below are two videos.

In this first video I am chasing a Multiplex Solius Glider. Probably one of the easiest kinds of RC airplanes to follow. It is flying relatively slow and is large and easy to see. This video was recorded on a GoPro Hero 8 camera. 4K60 with “hyper smooth” turned on.

In this second video, I am chasing a small 5-inch quadcopter that is running INAV firmware with a GPS. It is flown FPV in position-hold mode by a 80-year-old man in my RC flying club FK Gamen. He has been flying a lot of RC planes over the years, and now he is getting into FPV quadcopters. This video was recorded using my older GoPro Hero 3 Black, which I have since sold. The new Hero 8 was a big upgrade.

DIY FPV goggles

When I wanted to get into FPV a couple of moths ago I bought the Eachine EV800 FPV goggles with built in VTX and battery. I liked the idea that they could be used as goggles, and also as a screen. However, when that arrived I realised that they were very uncomfortable to wear, and I was not able to wear my normal glasses under them as I had intended. Therefore I only used the screen to start with.

I was not completely happy with the screen experience, I still wanted to have googles. Therefore I started to design my own goggle-part. I started with making a four part assembly in SketchUp to snap into the existing mount on the EV800, and also to hold the fresnel-lense in place. I 3D printed the parts, glued them together, and they fit perfectly. Since the shape of the rest of the goggles is very complicated, I thought it would be very time-consuming to design and 3D print everything. Therefore I built the rest of the goggles using cardboard, paper and hot glue. To make it look better and be more comfortable to wear I covered the entire thing in fabric, using more hot glue. I kept the part touching the face as large as possible to make them fit over my glasses. I finished off the design with some 3D printed parts to mount the original head strap from the EV800. I am pretty satisfied with the result. Now the goggles are comfortable, fits over my glasses, and is comfortable to wear. And I can still remove the screen from the goggles is I want.
