    You could be be right. But the arms on the ones in the video looked pretty thick. But my arms where a little bit longer. Maybe 18 inches. Not sure what resonate could of been a lot of things. When I moves to 11 inch props it flew like a dream. Scrapped the idea it couldn’t be efficient enough. I been working a lot on lighter frames without going to carbon fiber. But you always have give in take for weight and rigidity. Good luck!

    Well before you start. .5 inch wood booms won’t work. I couldn’t even get a 12inch prop going with out twisting. On 1/2 x 3/4 it was smooth balanced but once I throttled up it was dangerous. I was only able to get 11 inch prop to work on a quad I worked on. If your looking to turn a 15 inch prop. HK has some 25mm cf tube may give you what your looking for.

    I think it is neat. But being tall could raise the center of gravity. Make the controller work a lot. I think if you could flip it over, mount the motors on the other side might be better off. You know low hung. But it is definitely cool looking.

    I think it’s a fine video. And I understand what your saying. By the way still buying the cheap ones at hobbyking. With that said, I seen a video of a guy checking the actual power output on the boscam 600mw 32 channel transmitter. It varied by 300mw On different channel’s. Could this be the same problem? Different power on different channel’s on 32 channels?

    Hey thank you. I had been wondering for a little while about that. I think I remember David had a 4000 mah on a video. And I didn’t want to try one of the hi amp low C rating battery’s unless I had talked with some one first hand. I’ve built 2 hexacopters that could take a 5+ amp battery. But probably not at a 20C rating. Thanks for the info.

    I watched the video on the trakr and it looks neat. And I would say that’s affordable and light enough. But a fly away is really complicated in my case. It went up around 400 ft and a bit more than quarter mile over a 1100 acre farm. 30 even 40 feet. Is really small area. For all I know my quad 600mm. And it turned into a small black dot then disappeared. That would have been better than nothing. Seeing that I walked past it 10 times. Lol
    That’s when I started looking into the same thing. Even a bright strobe would have helped. You learn from your mistakes. Lol Always do a radio check!

    the only problem is sometimes you lose the battery on a hard crash. I did. Lol it was found when a tractor ran over it. lost in tall grass.

    Kind of curious I use a 2200 and a 3300 anyone use a larger battery? I was thinking of 5000 mah. Too heavy?

    This way you could power it with a couple of lithium button cells. Any fm receiver will work. Even better fm antennas are directional. It could be enough to get close enough to see the flashing led. I would pick blue. With a clear lens.

    What do you think?

    I’ve been concerned with the same thing. I really don’t think there is anything out there really available. If so nothing has been affordable or light enough. My thoughts would be a small fm wireless mic with a independent power source. Cause in a crash your battery usually separates from the craft. If you want to get technical you could power the thing with a 555 timer circuit. And make it flash with a led. It would be like a radio becon. A couple of miliwatts would be plenty. I’ll try to draw a diagram to make it easy to understand. That will be on the next post. A sort of block diagram.

    No problem with the phone thing. Mine does it all the time. Lol Opening it up is the last resort. But I figured if you don’t even get a blank raster it could be a power issue. But if it don’t have any problems while the camera and transmitter is on and working properly. It may be a software issue. I bought a couple Boscam transmitters and have one on my tricopter. And if the camera is not hooked up(monius) It don’t really do any thing. As for the fat shark goggles they normally have snow. As for my little tv I get a no signal and a blank screen. You might look over the manual and see if it has a video in switch. If it’s not over all the way that could cause issues.

    If you don’t feel comfortable with opening the case than don’t. There’s a lot of things flying a rc craft. Double that with fpv. 10 years ago this would be totally impossible for common people. So it’s totally normal to get a bit flustered.

    It might be a good idea to make up a check list for flying your craft and another one for your video like. To get set up to fly with my tricopter or quads. It usually takes me about a hour. I go over everything. You usually find this information useful after you have a fly away. Lol.

    Then I would take pictures like crazy at everything on the inside of the goggles the make sure you have a diagram of how to put it all back together again. After everything is put together set up the goggles. Usually the wire goes bad near a strain relief’s or near where the wire gets the most abuse. At the battery connector. I actually go through several wires on my cell phone a year. If you think the problem is deeper in the goggles you might be able to send them to the manufacturer. You would be surprised to know interested they would be for a manufacturer defect. Hope that covers most of the issue.

    Hi 2ma, I know there might be a couple of solutions to your problem. Anytime you trouble shoot you start with the most basic. In order I would check the connection at the battery then if the wire that connects from the battery to your goggles. Check the plug and check if it looks oxidized. If it has a hole in the center get a magnify glass look in the hole. Plug the power wire into the goggles and try to wiggle the wire around and see if you can repeat the issue. If it don’t repeat the issue, look at the female connector on the goggles. Find a tooth pick and see if the shaft in the barrel connector moves. If not, take the toothpick and see if the side of the barrel connector moves. If it don’t move and the problem don’t repeat. It’s time to look inside of the goggles. Use your camera and take a picture of where every thing is at. Open up the goggles and take a picture. Look at the barrel connector and see if there is a cold weld. If so use a low powered solder iron and re melt the solder on the connection on the pc board.
