  1. Hello. I would like to know whether its possible to use FPV goggles in an unusual way. I have Skyzone 04x goggles and I want to know whether I can somehow stream video from my phone directly to the goggles. Lets say I want to watch a youtube video on my android phone but I want to see that video in the FPV goggles. Any tips and clarification is appreciated. Thanks in advance.
  2. Hello. I am going to take an exam for flying A2 category drone. I have purchased a DJI Mavic air 2 without realising that it weighs more than 500g which means I must take an A2 cat exam. The topic for the exam : knowledge of the technical and operational mitigations for ground risks They do not provide any learning material, they do not give any topics to study from. The only things that I have heard, is that some of topics include: METAR Different weather conditions effect on flight Various safety/security questions Drone batteries Aerodynamics and etc I know that probably exams differ from country to country but perhaps some of you, who have studied drones and took an exam for A2 at some point could suggest me some learning material to read from? Thanks in advance.
  3. Hello. I would love to get into flying drones and now planning to buy my first drone. I am mainly planning to use a drone to get some nice pictures and cinematic videos. Initially, I was only considering mavic air 2, but then I found out that they are not compatible with dji FPV goggles which is a deal breaker for me. I think that FPV goggles are the best thing ever when you are operating and drone. I am now considering waiting for mavic air 3 and hope they are compatible with FPV goggles or build my own custom FPV drone and use a gopro camera. Could someone help me and advice me regarding whether custom FPV drone with gopro camera can get even close to image/video quality to dji mavic air 2? Also, I am also slightly concerned about the battery life with FPV drones and the preview quality since they use analog cameras. When I watch videos on youtube of people flying FPV drones, the video preview that they see through their goggles is ridicously low quality I cant even understand hand they manage to maneuvre so well when seeing this garbage view. And considering that the average flight time is like 4-5 minutes, so I assume the pilots just bring a bag of 20 batteries on a field?
  4. Hello! My question will not have much related to drones, but it is related to the glasses that most of you use while flying drones, therefore I would like to ask for your help! I am involved with a project which required to connect a 2D/3D vision goggles or fpv goggles to an external camera and see the camera view through the glasses. The connection between the goggles and the camera can be wired or wireless, I assumed that the wired connection would give me better video quality and since I dont need long distance I am considering wired connection for now. I have looked up few goggles and glasses: https://instashop.club/products/vr-headset-helmet-vision-fly https://instashop.club/products/visionhmd-bigeyes-h1-584ppi-2-5k-equivalent-screen-3d-video-glasses-with-hdmi-input https://www.fatshark.com/product/hdo2/ https://itvgoggles.com/fpview-3dhd/ So I need to have AV or HDMI input on my glasses so I can plug the external camera. Can someone help me understand which interface should I consider more? I assume the HDMI would provide me with higher quality video, but most FPV cameras come with an AV interface such as: https://pyrodrone.com/products/foxeer-t-rex-micro-1500tvl-low-latency-super-wdr-fpv-camera I prefer very high quality video preview and spend a little extra. Please advice me. Thanks in advance.
