Downsized from my DJI S800 to a DJI F450, here it is all finished with the FPV gear,

The props are balanced and it sounds really smooth and quiet while hovering, but when watching the video it sounds funny, but it hovers perfectly stable with the stock gains. The quad is balanced perfectly.

With the video TX powered up it doesn't have any effect on the NAZA/GPS, it gets full lock in our partially sky covered backyard in about 30 seconds.

BUT, I'm not getting a GPS lock on the Dragon OSD. It won't even get one satellite. The Torriod ring is wrapped up on the GPS wire but how everything is positioned it's only a inch from the OSD and the GPS.

I haven't tested the video TX range yet, hope to do that later today. I'm hoping I can at least get a few hundred yards.

BTW, this Dragon Commander is the best thing since sliced bread.
The only thing you need to test and adjust all the features and functions of the Dragon OSD is your Android cell phone and the Dragon Commander App.

Anyways, this is going to be a really fun FPV vehicle and I won't have the worries about crashing I did with the S800.

First test flight F450 (0 min 45 sec)

A few more photos.

I can't believe I got all the equipment and wires to fit in this tiny quad.
I'm sure a dedicated 3s battery for the FPV system would make it work better and I'f I can't get it to work like I want then I'll add a small 3s battery.

hey that's lookin' good. great video. seems like it's a smooth running copter. Love your back yard. I bet it looks great at night with all the lights illuminated.

I know, in a week or so I'll get some different props.

Glad to see you back!

So you were going to fly FPV with $2000 plastic frame? Cool.

Thanks,
Anyone have an idea of how to get a GPS lock on the Dragon GPS. Flew two batteries at the park and NAZA GPS was full locked in seconds but the Dragon GPS only got two satellites.

Ken,

Glad to see you back in the air! I agree with Photoship One on your backyard, WOW! Is this your new house? Looks like your 450 will be a keeper! ;)

Thanks Larry,

No. this is the house we are going to rent out, the new house we should be in there in a month or so. It was built in 1927 and had a few upgrades. This was here house before I met her. Kinda sad, she make more than double what I make. I sold my condo in California and moved out here to the friggin impossible heat.

Here's a few aerial photos our the current house. This is what gave me the idea to get into aerial photography and started the hardcore spending spree and the S800 and other things.
I'm totally happy downsizing and just having fun.

Don't know why the photos are still upside down when clicking on them.

Looks good man! Glad your back in the air. We still need to go flying!

Are you going to be using goggles for this eventually?

Try putting that toroid as close as possible to the gps. Also something that helped TREMENDOUSLY is putting aluminum foil underneath the gps so it blocks everything else out and focuses itself to the sky. Have you ever gotten a GPS lock?

There's only about 4" of wire between the OSD and GPS. The ring is sitting pretty close to the GPS as it is.

I'll try the aluminum foil thing.

the OSD GPS worked great on my F550/NAZA without GPS so I know there's no issue with the GPS.

Just a quick test video of the F450 with my ContourGPS. My GPS mount on the Contour is really worn out so it vibrates on the mount. When new sticky mounts come in I'm sure the video will look better.
