So here is my first attempt w/ fpv. I've been flying CP helis for a bit now (trex 450 & 600 and logo 800) and wanted to try something different. The rig is a DJI F550 system w/ the Naza flight controller + GPS module and Fat Shark FPV (Tx, RX, and display - goggles). The recording is from a GoPro mounted up front, as seen at the end of the video. I'm flying in GPS Attitude mode so flight is a bit slow. It's not very impressive compared to some videos on here but it's a start. Upgraded video tx and rx are already on the way. So far, w/r/t FPV, the first flight has taught me to take it easy on the sticks, as small movements on the sticks translate into big movements on screen. Any FPV advice would be most welcome. Thanks!

Congratulations! Your first FPV flight was pretty good. Look forward to seeing the next.

Would like to know about the goggles and what you have learned about the video tx/rx. Are you flying the machine on 2.4?

I am about to pull the trigger on fpv setup and dont want to have to buy twice. I have read more forums than I care to admit to. I am interested in the unbiased opinion of someone who has just taken the leap.

Thanks

The control Tx/Rx setup I'm using is Spektrum DX7 w/ DSM2 7ch receiver + satellite @ 2.4GHz. The video Tx/Rx is 5.8GHz.

The setup I'm running is okay. I say "okay" because it could be a lot better for just a little more money. With respect to the video, I would recommend a 500 mW Tx. The current current Fat Shark video transmitter I have is about 250 mW and while it is fun, I start losing range between somewhere between 600 ft and 1000 ft. Also, the goggles are fine, but I would recommend at least an external video Rx. I have already ordered a new video Tx and Rx. Also, the camera that came with the Fat Shark FPV bundled system is wide angle, so judging distance can be a bit tricky. I've ordered a cable to run the output of my hero 2 to my video Tx so that I can use mid and narrow views provided by the gopro. With that said, the Fat Shark bundled system works just fine and will provide you with a great start, however, you'll likely soon want to upgrade like me so it may be worth getting proper components the first time around.

The biggest piece of advice I have from my own experience is to suggest getting an OSD w/ altimeter reading. If you are like me and like altitude, the altimeter reading is a must. At the height shown in my posted video, it's difficult to visually gauge rate of ascent/descent visually and an altimeter is almost required if you want smooth shots during descent, IMO. Also, with respect to smooth video, if you are using a multicopter platform, a GPS module for the flight controller is A HUGE HELP; with it, you won't have to worry about drift at high altitude.

I hope my limited experience has been of some help!

Interesting place for the GoPro - how did you counter balance for having it placed so far out there?

Very nice first flight. Congratulations. One suggestion that will hopefully help out. Don't rely on the automated features of the flight controller such as GPS Position hold and flying in that mode. Using GPS Hold and things like IOC are great for smooth steady pans and shots. GPS RTH features are good for bailouts and problems. But if you get too reliant on them, it will act like a crutch that will be harder and harder to break. Practice some flights that would normally be in your LOS (Line Of Sight), via FPV, in ATT mode as a learning step. You can slowly navigate an area such as the field you were flying and practice navigating around obstacles to get the feel of the ship and build your skills. Then move to doing the same thing in MAN mode. Remember, you can always drop to GPS Hold or RTH features as a bailout for emergencies. I guarantee you'll earn quick, polish your skills quicker, and get way more satisfaction. Hope this helps.
