Ordered one, had it delivered. Wish it had better instructions and wasn't so hard to gedt up and running right away. Sending it back. Way too much to do to set it up for each model. Needs a better out of the box experience. Just too much stuff to play with.

​​​​​​im thinking ordering one up also in the next few days from Amazon! ill be using a link from a podcast for a different amazon item :)

thats awesome

Anyone have a quick/simple guide to getting the basic settings up and running easily. I do like the feel of the radio. I just need to know a quick way to change trim, dual rate, and sub trim quickly on the fly without going through all the lengthy steps for each model setup.

Thank you,

I want to preface this reply with; when using EdgeTX for new models, build a template model, and then copy it for each of your models.

For how to move the most used feature out of the menus and onto switches Bardwell does a good job explaining it in this video https://www.youtube.com/watch?v=DcJnIJSHdgg. I've yet to find a way of pulling sub-trim out to a switch. (I also haven't looked very hard.)

If you are interested in it, I posted my model template and telemetry LUA in post 219 and 221 in this thread https://www.rctech.net/forum/showpos...&postcount=219

I've got one of these on the way to try and I've been watching some youtube videos about edgetx and... I have observations.

The funniest thing to me is seeing all these FPV guys doing tutorials of how to set the radio up for a car even though it's obvious they have no clue what they're doing with cars. The most WTF moment was seeing a presumably pretty big FPV channel setting up a car. He gets everything set up in the car, turns it on, and tests the steering. He turns the wheel to the left, the tires turn right, and he's all "yup, that's right, don't need to reverse the channel." The cherry on top is he doesn't' even set endpoints and you can see the servo strain when the steering gets to the ends of travel. And none of these FPV guys bat an eye at the fact that radiomaster has throttle and steering flipped on the channels in the default profile.

And then watching surface guys use the thing is just as bad - too many get way too upset because the interface is not what they expect it to be. "hOw CaN i AdJuSt ThRoTtLe If ThErEs No tHroTTle mEnu??!!" It's like they're incapable of evaluating the transmitter for what it actually is and not what they want it to be.

For the record I'm a computer nerd, that like to dabble in just about everything RC. While I really enjoy driving my buggies, I'm not that good. I learned Edge/OpenTX from some whoop and toothpick sized drones I fly around the house. Again I'm not that good, but it is fun.

The best thing about, and the biggest pain with, this OS is there multiple ways to do everything. For the MT12 there is an odd mix of surface and flight terminology, which makes it hard to learn. So with regards to Bardwell, use those video to learn where the features are and come up with your own game plan. Why does he need an arming switch?

Given this is version 1.0 of an EdgeTx surface radio, I'm very impressed with it, but Radiomaster and anyone who follows them into this market needs to do more homework. The default model should have Steering Expo, trim, and Dual Rate/Weight* on the trim switches. Throttle trim should probably be there, but with an ESC does anyone really use it. (I'm old enough to remember needing to trim the wiper bar resister.) After that they need to include a quick start guide showing where to find sub-trims and endpoint adjustment.

* for anyone that doesn't know in the flight world Dual Rates are set to a multiposition switch. Each switch position has a configured maximum throw in each direction for multiple channels. As compared to the surface world where dual rate is a symmetrical endpoint on steering only.

I'd go with steering trim, steering "dual rate", brake EPA.

My application requires two or more grip dials like Trim5.
I have assigned the steering weight (D/R) that is most in demand to Trim 5, but I am using the combination of switch B and switch C instead of the second grip dial.
Switch C is very easy to use, but switch B is very difficult to use, so I modified it.

Just ran it in mod touring over a 3 day comp (half a day practice + two race days). Running the 3 Channel ELRS receiver on 3.3.0 firmware (later versions I read had drop out issues). This was double sided taped on top of my steering servo. Solid all weekend, no issues. I did note that the receiver takes a few seconds to bind to the MT12 once turned on, not that it matters. Just an FYI.

Yeah, the FPV guys have no idea what settings racers actually want. I made a point earlier that videos I’ve seen from them on the MT12 have them waxing lyrical about programmable features you’ll never use on anything other than a crawler, which is what they mostly drive. Give me throttle, steering, end points and some expo. Ok, maybe a timer if you’re practising. I don’t need endless programmable conditions that are useless to me racing. Edge TX does not translate well at all from aircraft to cars.
After a lot of initial setup pain, I’ve got it working for me how I want it. Still maintain I was better off going for a 4PM.
And first timers trying to use this dumpster fire of a UI. Good luck. It’s not logical or intuitive at all.

Mine showed up yesterday morning and I spent some time last night and this morning figuring it out.

I must say, even going in and knowing it was going to be some work to figure it out, it was still a frustrating process. And I'm pretty sure that despite all the boasting about how advanced EdgeTX is, it still isn't easy to do or perhaps even capable of doing things my NB4 can do.

One thing I wanted to do was use one of the trim switches to adjust the steering speed. You can set up a global variable that you can increase or decrease with a trim switch, but you can't use a global variable to define the value of the "slow up" and "slow down" parameters in the steering mix (which as far as I can tell is the only place where you can change your steering speed). On top of that, you can only adjust the "slow up" and "slow down" params in 0.1s increments which is just too coarse, IMO. For an OS that's supposed to be as powerful as it's proponents claim, why can't I use a global variable anywhere there's an option to enter a numerical value for a setting? And why do some settings not allow me to adjust them with the precision I'd like?

If the EdgeTX devs will listen to feedback from car guys then there's definitely a future for EdgeTX in the race scene. But if not, I don't know that it makes sense to recommend this radio for anyone who wants to race. The menu structure is just too complicated, which wouldn't be a problem if the radio truly was as adjustable and programmable as advertised. But it's not, so you're left with a UI that's hard to deal with and not more adjustable than something like an NB4.

However, with all that said, the feel while driving is very good. In F1000 mode with 333Hz servo PWMs the radio feels incredibly responsive, and while I wish the ergonomics were a bit more adjustable, the feel is still good enough in the hands. Performance wise, ELRS has what it takes to be a top contender in the race scene, but EdgeTX? Well, that could still use some work.

Absolutely I agree with you. I found the same issue with global variables as I was wanting to do the same with my servo speed adjustment, but I was going to put it on the front dial. This can and should be addressed. Feedback like this needs to go to the devs via the github issues page. This is the first version of a surface radio running EdgeTX and it's going to be rough all over not just the edges... pun intended. It took time for OpenTX and then EdgeTX to be more polished for aerial vehicles and I'm sure it will get there for surface as well. Might be 6 to 12 months or maybe more... hope not... but it will get better.

I just looked through the EdgeTX github issues and the enhancement for using global variables in inputs and mixes has been requested....

If you set Slow prec to 0.00, you can adjust it in 0.01s increments.
