Please tell us a bit about your UAV interest
Enjoy building and flying UAV of all kinds. Entered the hobby with multirotors but looking into fixed wings as well. Interested is different areas such as FPV, autonomous flight, aerial photography/videography and long range flight.

"Wow that's quite impressive! Can't wait to get a set, I feel like having the extra range would be good for peace of mind that I have a solid connection. Also looking into using something like this to be able to receive live telemetry data as well as…"
"I think 433 is slightly more susceptible to interference than higher frequencies? I guess it's much of a muchness, I'm only interested in the technicalities as the RFD900+ system is next on my Wishlist :)"
"I agree technically 433MHz would be slightly better at not being blocked by obstructions (and only slightly), but it is only legal to use up to a power of 25mW without an amateur radio license, so you would have to change the settings on the radios…"
"Yes certain types of transmitters are used for 3G on this band, HOWEVER Frequency hopping transmitters may be used between the frequencies of 915-928 up to 1W of power as long as at least 20 hopping frequencies are used. Both the 3DR radios and the…"
"The 915mhz used by these radios is 100% because it falls under frequency hopping. Totally different than standard 915Mhz band (ie 915Mhz cannot be used for FPV while it is fine for a frequency hopping data link). Can link the regulation article for…"
"915 is the way to go. You can only legally use 433 up to about 25mw but 915 in these types of frequency hopping radios can be used up to 1W without a license. The 3DR radios are only 100mw but it means you can use it at full power without worry."
"Long story short 915mhz is fine you do not need a license to use because of the way the telemetry radios operate.
433 can be used without a license BUT you must turn the power right down to 25mW in the settings."

"I've been using the ImmersionRC 600mW 5.8ghz transmitter so far and using the cloverleaf/skew antennas I haven't had any problems and the range is pretty good.
I recently started using a 5 turn CP helical antenna for the ground station through the…"

"I was looking at the same camera pan/tilt rig, at least to try out initially to get me started as it looks nicely put together and comes with a small camera (which i don't have one of yet).
At the moment I've just been using a GoPro hero 3 black.…"

"Yeah I think it's just the sheer size and power of the towers themselves. If the receiver and antenna on the tower is sensitive enough you wouldn't need the 3G stick to be all that powerful. Also the towers have many directional high gain antennas…"
"Actually right now they are just two whip antennas of varying sizes. I do have a large patch antenna I'll be using with an antenna tracker system. Just haven't range tested it yet."
"I use a larger 3dbi antenna on the drone and a 5dbi antenna on the groundstation and in clear line of sight I have made it 1km with almost 100% signal strength.
The stock antennas actually do surprisingly well probably 500m at least with no…"

"I would recommend the 915mhz. In theory 433mhz would be slightly better on range but as you can only use 1/4 of the power it's probably not as good in this case.
By default the radios are outputting their max (100mW) but it can be set in Mission…"
