The 1221 and 1222 are both 12 channel RX's

Status: offline 		I think the lack of detail re the stick position trigger has me a little worried . I have been using the 9309 since they came out
and I do need to up date pretty soon but to have the stick trigger and not make much of a fuss tells me it may be just the
same as the 9309 .

It does appear to be very much the same as the 9309 which is a good thing however I am at a point where my radio
does not support all the functions I require so at first glance the 12X seems to be a 9309 with some extra chanels and
a little more functions . I think I will wait and see .

Status: offline 		Probably the 12x manual is adequate if you have the transmitter and can play with the menus. As a selling document, it leaves a lot unexplained. For example, the default switch for throttle hold is the Mix switch. The manual doesn't show what the other switch options are.

In my years of R/C I have never needed more than six channels and cannot envision ever using more than eight. I have found no major limitations to the 9303. The better gimbals, faster response, magnesium housing, and the prestige of owning the top of the line JR transmitter are selling points but I am not yet sold on paying the price of the 12x.

Nothing spoils a temptation like time. If they don't hurry up and get the damn thing on the market I may lose my desire. I'm with the masses, my 9303s are darn good radios. Now why would I spend that much extra cash just to scratch my ego? I talked myself out of a new car this year by sleeping on it. I may do the same for a 12X. I'm going to Joe Nall and hold one. To wilt or not to wilt, that is the question.

Status: offline 		I,m in for one of these.
My LHS has my order for one, my price is $1450.
I bought 2 additional Specktrum 9100,s and will recieve 2 more recievers with the promotion.
Therefore I,m getting what amounts to $440 in needed recievers for free[ I,m just switching over to 2.4]
So my cost is $1010 for this radio system.
Plus a case and datasafe. Its a good deal when its all added up, assuming you like JR radios.

I went to Joe Nall, I held one. I'm in love. Who cares about money when you're in love?

Status: offline 		That's the way most things work. I'm a high-school senior, living in NC, about to go to college to major in Aerospace Engineering. NC State is a good school you say? I agree. But I'm about to make my parents shell-out the extra cash for Virginia Tech (though that may sound spoiled) because I absolutely fell in love with the campus. A lot of cars scratched my fancy, but I definitely had a first choice once my 18th birthday came around....because I fell in love.

My point is that it's all about what you want. I like Futaba because my dad told me stories of how much he loved his Futabas when he was young, so I've always been a little biased towards Futaba. It's what I learned to program and I've been pretty proficient since the day I learned. It's just a matter of learning Futaba's "language," and then they all become intuitive. I learned to program a T6XA and have been completely fine with my 7CAP, 6EX's, a 9CAP, a 9CAPS, 9Z. Once you learn it, it's really not an issue. I've tried programming a 9303 before but I really had little time to do it. I must say that I don't find it easier, I simply find it different. PJ Tank Pilot said it was the difference between task oriented and function oriented programming. He may have a very good point there. I just feel like for a little extra work I can really get my Futabas to do whatever I want them to do. At the moment, however, I'm considering trading my 72MHz Futaba for a 2.4GHz JR. Again, I love the looks of the JR (and its solid feel)...but I don't think I'll like the feel of the 10c (might be wrong)...but I don't like having to set-up 2 Rx's at 90* of each other (quirky, I know).

My point, I guess, is that competitors in a market like this are going to compete. The 9303 and the 10c are similar, 12x and 12z, spektrum 7 and 7c, etc.

My piece on the actual topic? Programming a JR I'd imagine is much like a Futaba...you know one and you'll get the other. It seems like the differences have been more than thoroughly explained. The only question remaining is if you, as the consumer, think the $900 difference between the 9303 and the 12x is worth having a newer radio, with a couple more bells and whistles, and getting your ego scratched. I personally love it, but as a soon-to-be-college-student, I don't have the money. I do have to say that if I had it, it'd be high on my list of priorities. Sorry if I was off topic, but I had to give my $0.02 on the situation since it seems like everyone else is .

I asked this question in this thread a while back. Apparently some of the ports (2?) are in the ends or sides. Airwayman

Sorry for reasking. I had skimmed thru the thread, but didn't see where it was asked before.

Status: offline 		All 12 channels have individual ports on the end of the RX. There are also BATT1 and BATT2 ports, and a Bind/Data port.

There are actually 15 ports on the same end of each R1221 RX. 11 of them or vertical like a normal RX and 4 of then are horizontal (across the top of the vertical ports)

They are all labeled and marked independently.

The RX is about the size of the regular 10 channel RX's however I think it is a slightly thicker maybe 2-3mm in order to facilitate the horizontal ports

The 1221 has one main antenna, and 3 remotes. The 921 RX's have 2 antenna on the main unit and a possible 2 more remotes. But the 1221 has only one on the main unit and come with the 3 remotes already installed.

This allows for for better antenna diversity. The purpose use using multiple antennas or remotes is because the signal is such a short wavelength. The antennas are short, and large metal objects on the model can cause signal attenuation problems. The remote antennas can be placed is a wider spread and give a better "Look" to the incoming signal. Futaba has the Long Wiskers to get the antennas further apart and JR/Spektrum technology allow the use of small postage stamp sized remote RX's that can be placed at various distanced away from the main processor. They sell extensions of various lengths for the remotes.9, 12, 24 and I even think there is a 36" This allows you to put "ears" further from the central mass of the model and the metal or dense parts of the model, batteries, engines, servos and other things that can partially block or be in the way signal wise.

Back when we flew 72mhz stuff the antenna was long. If part of it was blocked there was always some part that was unblocked. In the Spektrum technology the 2.4ghz stuff uses the short antennas. These can get blanked by objects like a DA150 or even a Saito 220 in the nose of the model. Antenna diversity means a better connection to the model, more ears in different locations.
