I don't disagree with any of this. There are some really great people here who make great posts and some of those people are very helpful and knowledgeable, I would call them out, but I don't think they'd appreciate it. I wish there were more of them, I wish there were more manufacturers on the board, but I realize this place isn't a priority due to low traffic and I also realize that some don't participate because they don't want to deal with being challenged/attacked by an end user, which is incredibly unfortunate (Yes, I am one of those who challenge/attack, but I assure you I don't ever mean ill will, I'm just trying to learn as much as I can about your product),.

I personally believe that the low traffic is due to some of the hostility and push back some encounter when they come here, especially when they are new to the forum. You are right, there was no negativity about the radio, but there was a little push back. I see the potential of this forum. I wish it was a bit less hostile. I get it, from the get go it's been a place where racers from around the world go to chat and that's awesome and should never change, but the url is rctech and I personally think that if this forum expanded to include things outside racing, traffic would increase, which would hopefully mean more manufactures on the forum, and bonus the owners would make more ad revenue. I know not everyone agrees with this and that's fine, I understand, agree to disagree.

To me this topic is just one big commercial crap talk topic. New users with usernames related to the transmitter, some talk about future developments and how wonderful the system is with all the possibilities that comes with open TX.It all sounds a bunch of people from some commercial department talking with each other.

At the end most users will use it as like any other transmitter.

Thanks for backing me up.

Again, not knocking down the radio (it may be a very good one, indeed), but I sincerely doubt it's special features will have much impact on RC car racing. Mixing channels is nothing new and has existed in flying for a long time. Nice to see that it apparently can be useful in crawling, too. But in RC car racing, people usually got their hands full enough with basic throttle and steering already without having to push extra buttons. Also don't forget, there's a reason why gyros and other such helpers are all illegal in racing, even though the technology is there and could help drivers go faster or make driving easier - but it's supposed to be all controlled by the human holding the radio - just like many real world 1:1 racing car series don't allow anti-lock brakes or traction control to this day, when even most road cars had such systems for decades now. So, interesting bit of technology? You bet! Going to revolutionize RC car racing just because it did with drones? Highly unlikely, IMHO. Maybe I'll be proven wrong, but so far I'm simply not convinced.

Would be interested in hearing your thoughts vs the NB4. Have any broad strokes thoughts you'd be okay with sharing? Would be nice to hear from someone who has actually used the remote. Too much noise in this thread from people who are just posting so they can read their own posts.

Outside of Karting what series' are these? The manual for the steering wheel for the new Hypercar/LMDH car's is required reading before the driver staps foot into the car.F1, anti-lock brakes and traction control, Indy pretty sure they are the same as F1 but could be wrong, all levels of sports car racing allow anti-lock and traction control. Outside of NASCAR and the NHRA there aren't any series' that I can think of that don't/wouldn't allow anti-lock or traction control. Does a stock car not use anti-lock?

Maybe this is what's good about new hardware and protocols - it generates interest and people who've not wanted or needed to speak in the forums before now have a reason.
I'm just getting out of flying and going back to racing. I did a few years as a teenager with Losi XX, XXX and XXX-S in the 90s and a period with a Schumacher 1/12th controlled series in early 2010s.
Since then I've been flying fixed wing, where the age demographic is the only thing keeping Spektrum/Futaba/etc in the game.
I'm in the market for a surface radio, and my flying experience tells me that this is probably the right one for the future.

I, like RC10Nick, want to know from Jakesterama what he didn't like about the radio for racing.
I also re-watched Jakesterama's Youtube vids, where he responds to a comment saying he did the ELRS test at 1000Hz, but the table of results at the end say 333Hz. Not bagging Jake, just trying to understand if there's more performance left in the radio.

F1 banned anti lock brakes and traction control ages ago.

Interesting and I apologize for derailing this thread. I was under the impression that F1 cars used different profiles like the LMDH/Hypercars do and assumed that adjustments could be made from within the car and assumed that those profiles/adjustments included changes to traction control and anti-lock. Completely new to F1, so that tells you what I know about it.

There's a grey area here though right - we can race with different brake expos, steering expo, throttle curve, steering speed - that stuff is only a step before ABS etc - can existing surface radios switch from one profile of those settings to another at the flick of a switch?

Some can, yes.

1000Hz is the packet rate between the transmitter and receiver. 333Hz is the servo PWM refresh rate. They're two different operating parameters. I watched his video, too, and it all makes sense if you're familiar with digital electronics.

Thank you for watching the videos! I'm not looking to get monetized or anything, but a video like that takes a lot of work, so it is nice to know it helps people.

I do not have a Futaba or Sanwa radio, and I doubt anyone at the track is going to let me open up theirs to solder a switch in to do the testing, haha. I'll be doing some slow mo video testing in a bit so I can non invasively do some testing.

You can not run your PWM frequency any faster than 400hz. A 100% pulse width for a servo or ESC is 2ms and you need some time between pulses. 1/0.0025 = 400hz. The servo manufacturers I use say 333hz max, so that is what I run. In my testing I had maxed out baud rate and 1000hz transmission rate for ELRS.

Speaking of being at the track, I took a walk around last weekend and it was 8% Spectrum, 20% Sanwa, 33% Futaba (more than half of them lower cost models), and the rest were Flysky Noble NB4 radios.

The MT12 comes with 0 adjustability out of the box, which is disappointing because even a $50 GT5 comes with a couple back straps. They copied Futaba's design with how the steering wheel mounts, but they didn't make it left hand swappable or offer drop-downs or angle kits. As mine is configured, it is 27% heavier than the NB4.

They didn't set it up out of the box for the few things that racers want easy access to, which seems like a miss. The one advanced function I actually use occasionally (ABS) is absent, and I have no idea how you'd actually accomplish it in EdgeTX. Maybe have to get crazy with delay functions in logical switches or something...

You can buy a NB4 with $70 worth of receivers right now for $185, making the transmitter "cost" $115, so it is actually cheaper than the MT12. And it has ergonomic adjustments, color touch screen, and a proven track record with some of the fastest most accomplished racers in the world using it.

Again, not trying to sound too negative here. I'm happy this TX exists. I'm happy Radiomaster is working in the Surface RC space. The MT12 just isn't for me at the track. I'll be using it on bashers and stuff like construction equipment and my FPV Xmaxx. Personally I'd love a low cost lightweight ELRS TX similar to the idea behind the Radiomaster Pocket to compete against the GT5 and Radiolink radios.

The limit of normal digital servo's is with the pulse width. The center pulse width is 1.5msec

Futaba its SR has a center pulse width of 760usec and so has a frame rate of 800Hz
The new UR has a pulse width of 200usec going up to 1500Hz
Sanwa its SSR has a pulse width of 300usec but still a frame rate of 384Hz but due the much shorter pulse the latency is dropped with 1msec
Sanwa SXR is I believe still using the 300usec center pulse but with a higher framerate.
Also the Noble pro supports SR up to 1000Hz

There is a topic of some measured speeds of the servo pulse.

I'll try this out at my local carpet track next time I'm there (next week?) on my reference car Yokomo CAL3.1. I'd do it sooner, but interest-level is what drives the order I do things, and this one is not super-high in the overall RC community.
