New to forum, new to "real" drones, looking to increase range.

I actually thought about mentioning yagi when we were talking antenna there but haven't ever used them for fpv stuff myself. I remember using some sort of yagi antennae for old school analog TV on roof tops and have read they are good for long range directional receiving (and I think transmission) but I've never tried one myself they may be worth picking up to compare for yourself. Think best info you can get on antenna is basically the signal pattern or how much "gain" they get on a signal in some position relative to the antenna. The other property is polarization of the signal which helps since two polarized things are basically "tuned" to signals that are at the same polarization so can help eliminate sources of RF noise from the signal.
 
There are people out there who make "DIY" antenna if you want to know more about what effects the signal and how would suggest checking that out. Also just lots of cool stuff to see :D there's a YouTube vid of some folks who built an antenna for connecting to NASA satellites I think glonass maybe but anyhow were able to download images streamed of earth from the satellite. Will post here if I can dig it up.
 
Woah, i'll watch that in a bit.

The thing you said about polarization - how much noise does it eliminate? For example, in a rural city area, where there are houses, and pretty much 1 wifi signal comming from each house, how much interference does it eliminate? I can get about 100m distance at 80m high with my drone with the stock dipole before the 5g FPV completely cuts out. But, remember it's DIGITAL not analog. So either signal or no signal.
 
Yah answer like in this vid is it depends:


Basically if you are flying inside or around a lot of metal things that will create multipath (bouncing of your signal) then the polarization can help eliminate noise you are basically making for yourself. If you are flying through a lot of brush or behind something concrete (basically stuff with high water content) then it will eat up or attenuate some of the signal this is when amplified signal can help. But it is a bit of guess and check with any scenario or particular antenna some of them are better than others so a bit of a crapshoot and matter of experimenting and finding what works.
 
Hey guys. I just had my first flight today with the drone. It went bad.
I was at a place with trees around maybe 40 meters away. I was flying normally at 90m altitude for a few minutes, without any problems. But then, my drone randomly came home on its own. I was able to control and move the descent and it went perfectly in the landig pad. I don't know why it did that. But then, i turned my motor back on, and flew up about 60m high, then pressed the forward joystick for about a second. After that, the drone kept going forward, even though at this point i was pulling the stick backwards. This was maybe 1 second. Then, it also started going to the right, so it was going forward and right. It kept going for about 2-3 seconds, when it hit the top of the tree. I have no idea why it did that. Can someone please explain it to me? It crashed, i heard a crack, went to get it, one of the landing legs broke off, and the camera gimbal is not perfectly level now. Also, in the landing legs, there is a white wire that goes into it (the leg is openable) and some kind of metal tube.

Should I try to glue it back?

I would. Modern plastic glues can make a very strong bond. I glued an arm back together on my X11, before purchasing a new one. It worked perfectly well and felt like a very strong bond. I broke the arm by holding my drone, whilst it was operating, so it fought against me, trying to stablise itself so that when I let it go, it flew straight into a brick wall with considerable force. My fault entirely. Is it possible that you were holding your drone in a similar fashion, or maybe had the GPS turned off, causing it to fly erratically for a few moments.

That looks like an air pressure sensor at the end of the leg. If so, it is quite important. My X11 experience is that it is a very robust drone so maybe the X12 is as well.

My X11 will return home, with almost no warning, when it decides that the battery is low, as it did to me today, when I was a long way from the launch site. It landed perfectly though as it sounds like yours did. Maybe the battery really was low and that caused a problem with the next flight? Just a guess.
 
Yeah, i glued it back. I took it to a test fly today, and i flew up maybe 2 meter or 3 meter high, drone was saying its 80m high, hovered a few seconds in place, started doing circles in a 3m radius, then flew away, I pressed return to home, it came home. I think it has a problem.
