FPSRussia on youtube is now into quadcopters. Cool video. Real or fake?
Judging Altitude when Flying FPV
I have just recently started to do my initial first person video(FPV) flights and found that judging altitude is one of the biggest challenges. I can take my quadcopter out a few hundred feet, turn it around, then bring it back and land it. However, I am constantly confused about my altitude.
OSDs and Gimbals
My rig doesn’t include an on-screen display(OSD) or a camera gimbal. OSDs are used to see graphical and numerical displays of various data including altitude. My display has no data displayed. I also, don’t have a camera gimbal that can adjust easily to different angles. My camera is fixed. I find that if I angle it straight out, I can see the horizon, but when I get high I can’t see the ground. If I angle it down, that helps me see the ground from up high, but I can’t see the horizon when I am low.
A gimbal, a new camera, or an OSD are all ways that I might fix this problem. Instead, since I am not an expert pilot, I decided to fix my problem by buying a controller with good altitude hold. Altitude hold will keep my quadcopter locked at a specific height so I can concentrate on maneuvering around. To accomplish altitude hold a flight control board must have either a barometer or sonar or both.
There are lots of inexpensive boards that have barometers, but the board’s firmware must be well written to take advantage of them. My research has led me to the DJI Naza Flight Control Board. Though not inexpensive at around $230, I think it is the best value for FPV flying with excellent altitude hold. It also appears to be very easy to use and configure.
I haven’t received mine yet, but ordered it today and will report back on whether it improves my FPVing.
How to wire a quadcopter is often assumed to be common knowledge, but when I started to build my quadcopter a few months ago I knew virtually nothing about rc wiring or electricity and had to search around a lot to figure it out. This post is an effort to describe what I have learned and how I wire my quadcopters.
There are lots of good wiring diagrams on the net, but sometimes they can be confusing to read, so I took this picture to describe how I wire my quadcopters:

The HoverThings HT-FPV Quadcopter Frame is now available in limited quantities at HoverThings.com! This quadcopter frame was designed specifically for first person view (FPV) flying with the arms and propellers out of the view of the camera. There are lots of other great features including plenty of room for gear. I doubt these cool frames will last very long.
