I need to add at least few mm of throttle travel. Is this possible by any mod? Or do you know any transmitter with longer throttle travel than NB4? Thank you

Any radio on the market will allow for a max throw of 120%, if that isn't enough then it's time to either adjust the servo horn or extend your linkage.

F/W .93 FCC. 2 buggies with FGR4s and 1 with FGR4. Finding that I only get around a 3rd of the range in specifications. About 40-50m with FGR4s and about 110m with FGR4, supposed to be 200+ and 300+ respectively. I can only assume that its a problem with the TX as it's short with all 3 receivers. I remember when I first got it it was glitching out on one model saying the RX voltage was low even though it was in the proper range. I upgraded the FW to .93 and it continued to do the same thing! Had to remove the model, reset and reinput the model on a different model# to cure. (I later input a different buggy in that spot and it seems to be ok). Now I'm finding this range issue which bothers me immensely, 50m is near useless even for racing, and I'm really a basher so I can use at least that if not more. This is the case in any environment I have used it in, including a farm with absolutely no electrical interference and no trees blocking line of sight. (which clearly LOS matters with these because if I point the TX in the opposite direction I loose range far sooner). Flysky doesn't respond, but even if they did they respond only with gibberish because they don't understand the question. (I know because I asked them for help once already about the battery voltage thing, a pointless endeavor). Can anyone shed some light on this for me? I have mine set for 2-way, but I'm not under the impression that 1-way will improve range. What else, mmmmnn... batteries fully charged, tried with RX's out of the models receiver boxes. It's not just the alarm either (which you cannot silence unless you silence all alarms), I actually loose control. $250 pile of trash at this point, unless someone has ideas. Thanks all.

I always thought 1 way would give much more range. It tells you signal strength on the display, what are you seeing there (vs distance)? I've not had any issues with distance, but I'm not speed running either. But, the glitching thing, I dunno, that's a wildcard.

We can forget about the glitching, I seem to have cured that - just mentioned it because I did have some weird problems with the unit before. As far as signal strength, drops to about 30ish% around 60-100m depending on the RX model and then looses contact all together. Right now it's a useless paperweight, weird because others report 1000ft range with the antennaless RX when I can barely hit 200ft even in a farm field with no sources of interference. I'm not speed running either, just a buggy.

1 way mode won't really give you more range, it will give you better/faster latency due to eliminating the extra data traffic the rx/radio has to send/receive when in 2 way mode. I think people are definitely being disingenuous if they are reporting 1000ft range with the antennaless RX, I'd be interested in seeing a video and not just some claim on a FB page. I've also experienced the shorter range (about what you get) when using the antennaless RX and that's with my Pro.

I know there are two antenna ports on the RX board and I don't recall if someone confirmed if the second port works or not, you'd have to do a search, but it may be worth checking that in the event your TX antenna was plugged into the wrong port?

Thanks for the info, so far from searching the net it seemed I was the only one who had bad range - everybody reviews and tested with excellent results and better than spec. I'm confused about your port comment, how is it an antenna can be plugged into the wrong port on a RX or TX? especially the S receiver does not have antennas at all and the TX also does not have an external antenna. Ultimately, I've got three RX all coming up with horrid range, has to be a transmitter problem.

What I meant is that on the Noble's circuit board, there are literally two antenna ports in which the factory could theoretically plug the antenna ipx connector onto. Again, as posted above, I believe someone had looked into the ports but I don't recall if one of the connections was live or not. Takes nothing but a bit of time to look to see where your antenna is plugged into in comparison to what others have. This is a long shot of a fix in any event but again, why not look.

Out of curiosity, I may do a range test using the FGR4P this weekend if time allows as now I'm curious.

Ah yes, tracked it down and researched all the info. However the writer and experimenter had mentioned later that his efforts really didn't yield any difference in performance by messing around and adding external antennas and such. My take on all that was that there's simply 2 positions on the circuit board for antennas but connect to the same antenna amplifier circuit. Be it one connector or the other, I doubt as if it would make a difference. Having said that, since mine is just a little more than a door stop at this point without Flysky adhering to any warranty policy or support, maybe I should crack it open and start messing around. Worst case scenario I make it worse, but it seems I have to go and buy another remote anyways. I liked the flysky, but from day one found the tech support from the company a joke.

I've been doing a lot more long distance testing with my NB4, it seems pretty clear to me it's broken (or something out of whack). Maybe some of you can tell me what RSSI means? I saw a video of a guy testing latency and he had the control right next to the model. His display showed 36. Meanwhile, when I'm sitting beside my models it displays in the 90's (no matter when or where I am). I cannot find anywhere in the NB4 literature or on the internet what this figure is and how to interpret it. I did realize during some testing yesterday to find answers that I don't loose control of the car as soon as I thought. I found I lost two-way communication at around 50 meters distance but I still had control of the model until at least 100 meters. (not clear how much more I could eek out of it during yesterdays tests since I ran out of room). The race receivers are supposed to be 200+ meters, but it's clear something is amiss as I don't hear any talk from people about loosing 2-way telemetry and getting the voice warnings at only 50 meters. Either way, all 3 of my RX's are coming up short by 1/3 of the spec with regards to telemetry - and although not measured yesterday I feel last time I used them they can't reach 1/2 the spec before loosing control. Again, can't be the RX's. There is no way 3 different RX's in 3 different cars in any environment I run them in could fail at the same time - something is up with the TX. I'm hesitant to tear open the TX and inspect, it's still basically brand new and I'd like to learn more by comparison to others before I start turning screws. I really need your help out there folks. Flysky and the vendor are both ignoring my request for support and/or possible warranty service. It's basically a $250 paperweight now, unless I can figure this out.

I know it sounds stupid, but have you contacted them on Facebook and/or posted about it in their NB4 Facebook group? DM me for the direct email of someone at FlySky.

Received Signal Strength Indication

LOL, thanks. Google searches already revealed this, however I can't figure out how to utilize this information to troubleshoot my concerns.

I'm contemplating a higher performance radio for racing buggies, using a FS 5 currently.

Razor RC's review of the NB-4 mentioned deadzone, which people say is solved in the NB-4 Pro, and which isn't necessarily a deal-breaker for me anyway.

He also mentioned the NB-4 having a non-linear steering curve (search "razorc flysky noble nb-4 nb4 full review" and he discusses it from 12m44s in his video - I can't post a direct link). That probably is a deal-breaker for me, especially when combined with the minor deadzone issue.

I haven't been able to find anyone else with this complaint or any update on the complaint.

It seems like the sort of thing which could been a software bug that's been solved - is it still a thing? Was/is it fixed on the Noble Pro version? Was it just one bad transmitter/batch all along?

I watched that video, he certainly talked a lot about he felt about the radio... but I didn't see where he made sure the steering servo mode and frequency was correct. I have seen steering issue comments on forums and most are corrected by the correct settings for the servo, as far as I know. And his comments about people who like it probably just arent good enough to know the difference is a little off-putting. Especially since he doesn't dig deeper into his feelings about the radio and back it up with some data. A lot of reviewers have done slow motion video regarding the claimed 3ms response and I can't say I remember dead zones and expo issues being discussed. I read through his comments, it seems like some commenters are happy with theirs and dont have the issue, and others commenting about the issue seem to be echoing his opinion, not actual owners. *shrug*
