In this instructable I will try to help you with finding the right FPV goggles, and flying an FPV quadcopter.
Step 1: Finding the Right FPV System
Finding the right FPV system is very critical. Personally I have the fatshark predator v2 goggles. But, there are many different types of FPV systems. you can choose from watching the video on a screen, or on goggles. The goggles are generally a better bet, but they are also more expensive. If you are going to get into the hobby for aerial photography, then you will probably want to go with the fatshark predator v2 or better. Although, if you are just wanting to fly fpv for fun, than you will just need the fatshark teleporters. I have found that you really don't need that high quality of goggles for flying, because you dont need to see everything in HD.
Step 2: Finding the Right Spot
When going to find the right spot, you need to make sure that you are in a very large field with nobody and preferably long grass. Whenever you are about to do your first flight, bring a chair, because you will feel like the world is sideways. Just so you know, the first flight will not be easy. You will want to stay low and stay close. You will want a spotter with you so that way you can ask them questions, and they can let you know where you are.
Step 3: First Flight
Whenever you are about to take your first flight make sure that you have nearly mastered line of sight flying. To take off the first time you will want to try it with the goggles on. If you aren't able to take off with the goggles on, take of without the goggles on. Once you are about 20 feet in the air, put the goggles on. Try to hover, but if you find that too difficult, then just fly around making sure to stay away from any trees or power lines.
Step 4: Mastering FPV
After you feel comfortable with the basics of flying fpv, then you can try flying higher, and further away. Also try and fly around trees. Just make sure that you know where those trees are. Once you feel comfortable with that, I think that you can officially say that you have mastered flying FPV. If you have any questions, please just ask them in the comments.
