Very nice! I am glad I am not the only one enjoying this sweet, sweet radio! I am about to go put some more time on her as soon as I get my Ion programmed up in the 12X. Word.

I got the N9 programmed and am about to walk out the door to test it out.

Let us know how does the radio feels and your first impressions after the flight?

Can you tell me how the swich assignability on the 12X compares to the 9303.

Thanks

Took the two helis I've programmed so far, a 600N and an N9, out back for a couple of flights with the 12X. Coming from a 9303 with Spektrum module, these are my observations so far -

The radio feels very solid in my hands. It feels just as well built, if not better, than the 10X. It is noticeably heavier than the 9303, but in a good way. Unfortunately it doesn't balance with a neckstrap any better than the old radios when you removed the antenna. I had to use the Spektrum adapter to get it to balance properly.

The gimbals feel very good and are ultra-smooth. As I posted earlier, I can't get them quite as loose as I am accustomed to so it did feel slightly different to me in that regard, but I'm sure I will get used to it in no time.

I was using the R921 in both helicopters, and everything felt a little more responsive with the 12X compared to the 9303. Both helicopters felt more locked in and seemed to do exactly what a asked, almost before I asked. I'm sure it's the doubled resolution that is making the difference.

The timers are not loud enough. As I was setting up the radio on the bench I thought they seemed plenty loud. At the field however, I didn't hear them once. I even set both timers so they would sound 15 seconds from one another. Never heard either one during any of my flights - and it was not windy outside either. I guess I'm just going to have to train myself to listen for them a little harder.

All in all I'm very pleased. I don't think it's going to make me a better pilot, but at least I'll feel good walking out to the flight line.

I just put 2 more flights on the 12X. One on my Razor and one on my V-bar X2. I have to agree with everything creightoncarr said, including the alarm volume. I love this radio!!

"About 6 months later he returned it - not working! He'd rebuilt it into a new sexy black case they were trying. Could I get it to work? Could I ****! I spent HOURS trying to get the RF output stable! It was driving me mad!

Eventually I rang said manufacturer.

"That's funny!", he said, "We can't get it to work on 35 MHz either in that case!!!"

The antenna has to be black too, for it to work.

Thanks for the update on the timer beep volume,

I have the same problem with my current 12FG but is in the process to "modding it", adding an extra beeper/buzzer, will see how it goes, perhaps its something that can be applied to the 12X too.

It was something to do with the material they were using to anodize the case. The black stuff was totally non-conductive, and you couldn't get a proper earth connection to it!

Funnily enough one of my current models is powered by an AirSupply 40 motor. The crankcase on it is treated black, and again its impossible to get a proper earth connection on it. I can't use a remote glow connector for this reason, and its an absolute pain in the rear having to remove the canopy every time to start it!

Otherwise, its a great little engine, though!

Here was the first flight with the 12X. Nothing spectacular, and a little sloppy I think as I'm getting used to the feel of the radio. Hopefully get a chance to get out today and get a couple of good flights on it.

I should test mine on a Raptor 50 later today.

With regard to the case, I have changed the velcro strap to one that I can just unfasten from the top. The case is very nice but somewhat awkward, to say the least.

I may remove the small storage area in the bottom and see if I can use it to transport the 12X and the 10X simultaneously (sitting vertically).

OK,

Seven flights on a Raptor 50 this morning.

No mechanical changes, just radio normal radio set up.

The 12X/921 replaced a DX7/AR7000.

I think JR is right-I can "feel the difference" (even though the DX7 is really a re-badged, good, solid, mid-level JR radio with a Spektrum rf board). The Raptor 50 has always flown fine, but just fine. It may be my imagination, or the fact that I have now flown it much recently, but I do believe it felt better/more responsive to my commands. I hate to use the now cliche term of feeling more connected, but it did.

Setting it up with the 12X was much easier as well. None of this is intended to be taking a shot at the DX7 (which I still like and will continue to fly in some models).

The conversion from the DX7 to the 12X was not quite as dramatic as the conversion from the DX6 to the DX7 in the TREX 450, but quite noticeable.


I like it...

I just got one from the LHS. I got to admit, I don't miss the 10X touch screen anymore. I don't know how else they can improve this radio, except to include lithium ion battery as stock. The only negative thing is the way the case looks. My buddy is mocking the case - it looks like one of those make-up case from the 70s.

Has anyone who bought the 12X tried to use it with Phoenix RC sim yet? I cant get the software to recognize it. Hmmmmmmmm.

Got my 12x today!

First impressions:

-Feels great in my hands

-Battery "cartridge" is very lame, they should have changed to a charge jack on the side of the radio. I wanted to use the same Eneloop pack I used in my x9303 but thats not going to happen without soldering.

-A rubber plug for the 72Mhz version antenna hole would have been a nice touch, if they are going to charge the big bucks I think they should finish it a little better.

-Noticed the LED on the back for the Spektrum portion is orange like the receiver LEDs instead of the green found on other Spektrum transmitters.

-I much prefer my Pelican case to the included make-up case.

-The aluminum stick ends on the gimbals are threaded differently then my x9303 so using my Red anodized Jr sticks only works if I want them super short.

-The throttle curve seems to be designed to have the mechanical throttle trim all the way down, on my x9303 its based off of having the trim in the center.(maybe this can be changed somewhere on the 12x)

Not trying to be negative, just pointing out everything I've seen thus far. I know once I use the radio a little I will love it!

Anyone have any hints as to how to remove the rear panel so I can have a peak inside?


EDIT:

With respect to using the 12x with a sim. I just tried it myself and it didn't work. I scoped the output and noticed the data coming out of the trainer port is *not* standard PPM. This makes sense as you can't have a normal PPM frame with 12 channels in it.
The work around is to select a new model for sim use and then goto the trainer menu and change it from master to slave. The radio will now output a standard 8 channel PPM frame. You can assign various switches to work as throttle hold and idle up etc. Its working for me!

Regarding the throttle curves, I was used to having the output at 0 at the bottom curve position with the trim centered just like you. I don't think there is anyway to do that on the 12X without setting the trim value to 0%, essentially deactivating the trim altogether. I just shifted everything up a little bit and figured I would get used to the new curve positions.

Thanks TheSteve...!!! I could not figure how to get around the digital signal. This should work out fine.

How is the antenna fitted? are you able to turn it around and adjust it like you where able to do on 10X? On the picture it looks like it is secured/fastened?

Yes, the antenna is movable in the base like the 10X.
