I was browsing hobbyking and saw the advert of the new transmitter
9XR Standard Features:
• 8 Channel PPM/9 Channel PCM
• Full Ball Bearing gimbals
• Adjustable Stick Length
• Digital Trims on all Primary Axis
• 16 Model Memory
• Assignable Switches
• Freely Assignable Channel Mixes
• Graphical Dual Rate and Exponential
• Sub Trim and Travel Adjust
• Flaps and Differential
• Throttle Hold
• Supports Heli/ Aero/ Glider Model Types
• Programming Templates Based on Model Type
• Supports M1, M2, M3, M4 stick modes
• 128 x 64 backlit Liquid Crystal Display
• Built in JR & Futaba Trainer Ports
• PPM & PCM Output
• JR Form Factor RF Modules (Orx Dsm2, Orx Open LRS 433Mhz etc)
• Programmable Timers
• Low Voltage Warning and Buzzer

The ISP interface is going to make this very interesting.
Comments
Mine does indeed have an antenna in the handle
I know this is an old post but I want to mention a correction....The 9XR does NOT have an integrated antenna in the handle, as you need to buy a TX module to use the radio. Any JR style TX module snaps into the back of the radio.
Yes, I think the LiFe cells are the way to go for transmitters: the voltage drop off is more gentle than that of LiPos and they don't catch fire (so easily) if abused...
These cells are around 3Ah and are wired 2s - not 2S, 2P as I said earlier. http://www.ebay.co.uk/itm/2x-SenyBor-2800mAh-18650-3-7v-2C-5-6A-dra...
I came close to buying one but after reading mixed reviews I thought I'd wait a while. I have a 9x that I installed the sky9x version 3 board in and frsky RF unit and added rotary encoder that works very well for me and has a lot more ability.
Further to the above I am using 4 LiFe cells connected in 2s 2p to give 7.4v plus to the tx. You can use 3 cell Lipos but anything over 5.5v is regulated out as heat. Two cell lipos are fine. The LiFe cells are cheap on ebay and are extremely durable; you can charge the h*ll out of them - don't belive the mAhr claims as they are grossly exagerated unless from a reputable supplier. Good examples are produced by SenyBor and one of the few whose capacity claims are accurate (2800 mah - I use these). These batteries also have the advantage of fitting in the 9x battery box.

I have used the original 9x with Smartyparts boards and ER9X with 100% reliability. I have recently added the Flysky telemetry module which, although I have not got around to using all the possibilities, has the great bonus of beeping at me when it's aproaching the edge of its range. I am using this system with the APM 2.0 to great effect.
As others have reported the quality might not be as good as some of the better transmitters but, despite that, it's the best I have used and has not let me down in any respect in over a year of use.
If there is a "bleed over" of controls it's probably due to a too wide pulse width on one channel. This can be checked in the APM Mission Planner under "Configuration" and the button that checks the flight functions (ie stabilise, auto etc). Another coment was that the back light was not working; this needs to be turned on in the set-up page of the ER9X firmware.
I am now using Open9x firmware which seems to have added options over the excellent ER system - http://code.google.com/p/open9x/ its worth a check.
Cheers,
Mick.
Thank you very much for your detailed report on that radio. The rudder/throttle - thing must be a new feature.
Actually I was able to get a Flysky 9x in Europe (UK) and I thought, I bought a clone, thanks to you I know now that I have the original :) .

I just received yesterday 2 9XR radios from HobbyKing. Did not have any bigger expectations for it but hey price is also not bad. Ok i bought Mode 1 radios as Mode 2 is always out of stock and figured out that it's not so difficult to modify them.
Initial impression was rather nice on radio it self. It looks fancy from outside but have small plastic feeling.. well it's full plastic :)
Immediately when i switched it on I started to notice why it's only 49 USD... Multifunction key is really multifunciton key, you never know what happens when you press it. It just does not have proper feeling and even if you press it properly lets say from up, you might get down press in reality.
Menu and Exit buttons has goofy feeling too. Switches and Pots works rather ok (I have old Turnigy 9x that got rusty after 6 months)
Anyways, I opened my radios and started to look how to change them from Mode 1 to Mode 2 (I will make bigger blog post later when i have some free time) That was not so easy as in original TGY radios. You really need start using soldering iron and move PCBs around sticks. Also you need to move all sticks and their full hardware from left to right and vise versa.. They use really low quality PCBs and connectors that are directly soldered to joystick potentiometers.
In overall PCB quality is really low on it. Ok does it matter so much if you just use it and never open. Maybe not... Let's see how they work after 6 months or so.
Modify process took about 1 hour or so.
Another calibration as now all joysticks and potentiometers are on different locations.. Things went ok so close the box :)
While playing a lot more with it's settings etc. I noticed that throttle stick and especially it's rudder behaves bad. When moving throttle from 0-50% no problems but after around 60%-90% i noticed that also rudder starts to move ?!? Ok maybe i forget one it's cable on bad place so opened radios again and checked that no problems.. No cables were just in correct places. Next thought was that hmm maybe just a bad calibration so let's do that again..
I did calibration again and even during calibration I noticed that while pushing just throttle up and down. Between 60-90% (thr) also rudder moves. It looks like it's their hardware is flooding to another channel a bit or software problem but you just cannot make rudder to stay still while moving throttle.
And it's not a small amount it moves. It moves almost 10% to "left"
Noticed this same thing on other radio that is still fully unopened.
I started to google more about it and went to youtube, it seems to be full of guides "how to fix this and how to fix that on 9XR radio" so I am not alone.
But ok it's nice radio and really cheap, if you are willing to spend a lot of time to tweak it and change some parts then it's worth to take but if you are not skilled engineer/hacker.. Well you decide.
Ok there are few nice things like both Futaba and JR trainer ports, ISP port on bottom for flashing it and it has Turnigy customized er9x software in.. Which version I don't know as it did not show it. One thing that I am really sad is that as they fully copied this nice opensource software to it.. Why in earth they did not put Serial port pins to it?!? So people could connect FrSky or what ever telemetry on it. Oh well, maybe i need to make new radio that have it too :)
But anyways, with 49 USD you just cannot get good components, not even from China or should i say "especially not from China".
And I would say that I know them rather well as visiting there almost every month. I still live in Asia if you forget :)
Btw someone sayd that FlySKY is clone of Turnigy, No it's not.. FlySky is original maker of that 9ch radio and they still make those. It's factory price is almost double compared to Turnigy radio. HobbyKing OEMs their TGY radios from FlySKY with low quality parts to push it's price down.

This is really old news and a stale upgrade at best. The HK model is really a steamer. Check out what Bruce says on RCModel Reviews and see first hand. Stick with the original and accept no substitutes. Get the SmartieParts http://www.smartieparts.com/shop/index.php?main_page=product_info&a... board and eXR firmware and you have a radio that no one can touch.
