well iv'e had a smart controller for over a month and am disappointed , the range lets me down constantly compared to my old rc and in the hand i find it uncomfortable , only good point is screen brightness , a lot of dosh for little gain !
Common DJI failure to correct.
Tons of posts over on mavic forum about the issue.
I even bought my $549 dollar RE's for 375 used from
a guy who turned them back in for the issue.
Since I couldn't actually return them, I kept them and ordered
the DJI lens inserts and they work great for my eyes.
BUT we are all hoping and praying DJI will find the time
to correct this issue. Although one guy stated that
he could get more range by custom switching to
2.4 ghtz. I am waiting for spring to test his idea.
I have: Spark, Mav1, MavPlat, Mav2P too.
Come on spring...
So far every reputable review I've seen on the SC has been glowing - if there is any mention of range, it has been to say that it's *better* than the stock controller. I have no issues with my SC personally, which is all I can really vouch for. I have very large hands and find it so much more comfortable to hold than the standard controller, and it feels of very high quality in the hand, everywhere except for the S/P/A switch - that feels oddly cheap.
Are you sure you are in FCC mode? That's the first thing to check if you are experiencing short range issues. Other than that the M2 switches between 2.4 and 5.8 Ghz automatically based on what is best.
If you're in FCC mode and you aren't getting good range in an interference-free space, maybe it's time to exchange it for a new one.
there is definitely a correlation between count of total posts to the forum and the expressed level of negativity in such claims.So far every reputable review I've seen on the SC has been glowing - if there is any mention of range, it has been to say that it's *better* than the stock controller.

But it is really hard to get a direct comparison because just a few minutes difference can change the interference even if flying the same path.
Here is a question for all the tech guys out there (I am not one). Does transmission power of the remotes (standard vs smart) matter? From the manuals -
Standard Remote
Transmission Power
2.4 Frequency
FCC <= 26 dBm
5.8 Frequency
FCC <= 26 dBm
Smart Controller
Transmission Power
2.4 Frequency
FCC 25.5 dBm
5.8 Frequency
FCC 25.5 dBm
Since this is a log scale does a potential 0.5 dBm difference matter? Also, less than or equal to 26 could mean 25.5, who knows. Again just thinking out loud. In CE mode the smart controller seems to have much lower transmission power (18.5 dBm for SRC and <=20 dBm for standard).
I have no idea if any of this means anything I just find it interesting.
Positive dBm values represent transmission strength (like for these remotes) and negative dBm values represent receiver sensitivity (like your smartphone on a WiFi network).
The way DJI has listed those specs is somewhat ambiguous because for the standard remote, they do not use a decimal place (which means it could be identical to the SC at 25.5, simply rounded up), and they also say the transmission power is "less than or equal to" 26 dBm, which is ambiguous in itself. For the Smart Controller, they simply list 25.5 dBm, which could just be the same 26dBm of the standard controller with an extra decimal place of accuracy. Further, they do not put a "less than or equal to" qualifier on it like they do for the standard controller, which possibly could mean it is consistently stronger but that is pure speculation - hard to believe they would go to that level of detail when providing the general public with specs.
The difference between 25.5 dBm and 26.0 dBm is measurable though, the former is 355mW and the latter is 398mW, a ~12% difference. I suspect environmental factors would have a greater impact than that difference, it it exists, but it would be very difficult to test accurately. I also imagine there ends up being at least 0.5dBm difference either way with manufacturing variances. My personal guess is that for all intents and purposes, they have designed them with the same transmission power - if there was a significant difference they would have to also adjust the 8KM max rating.
nothing to bash here, it is just all those complaints about range really sound like an attempt to claim that "A + B" somehow not the same as "B + A".
DJI did not use any new tech in the smart controller - it uses same transmitter with same antennas. so, theoretically, it should not have resulted with any significant changes. yet, who knows.
may be some units are less lucky than others and have some interference from the display unit, dunno. mine doesn`t.
