With v2 firmware update, correcting many flaws of the previous 9X, plus inbuilt 2.4Ghz (no daggy second antenna) this is a quality, reliable 2.4Ghz system suitable for beginners and pro pilots alike. Get that locked-in feeling that only 2.4Ghz glitch free technology can provide. Ultra fast reaction times and interference-free control of your model is only achievable with this 2.4Ghz technology.
Without a doubt, the best value 9Ch system available!
Number of Channel: 8ch ppm/9ch pcm Display: 128*64LCD Support Type: Heli/Acro/Glid Support user: 8 Stick model: 4 Encoder type: ppm/pcm Subtrim: Yes Simulator Interface: Yes Buzzer: Yes Low Voltage Show: Yes
Important. The TURNIGY 9X has been reflashed with the new v2 firmware, fixing previous menu and mixing issues. This firmware flash is only available from our TURNIGY 9X system as we flash each unit in our office before it is shipped. Purchases of any other rebranded version of the TURNIGY 9X will not have the latest firmware and patches (even the OEM factory does not have these updates).
NOTE: "SWITCH ERROR" means you have one of the switches in the wrong position when you turn the radio on. It is not a fault.
I just went on line to the only one that I know conected this reciver to F3 Deluxe Flight Controller ,and although it is called a ppm system it only works as a pwm reciver, anyone that knows of another way pls reply.
WARNING: Do not adjust the horizontal trims during flight, if loss of control/fly-away is likely to present a danger to people/property/your model! There is a design flaw with the grounding of the horizontal trim switches (grounded to the analog gnd plane, instead of digital) which sends big voltage spikes to the processor. This can cause the firmware to reboot, freeze, or otherwise glitch. It is possible to mod the unit and correct the grounding, by cutting pcb traces and adding two wires. But, even though this issue has been known to the RC community since at least 2013, my 3 month old unit still suffered from this issue, until I completed the modification this morning.
Beyond that critical issue (which actually caused a brief flyaway and crash last night). When I first received the unit, I had to open the unit and re-solder the orange wire on the right-rear switch which had detached, causing a Switch Error that wouldn't clear.
At the end of the day, I would say the savings are still worth all of the soldering and cutting I have had to do (I probably wouldn't feel that way, if my quad had been more seriously damaged, lost, or had caused injury or property damage in the fly-away).
Given that the difference between model 1 and model 2, is the location of the centering spring-clip, I would say the issue is with all models. You won't see a problem every time you adjust the horizontal trims (unless your tend to click them 10-15 times, during a typical session. When I would click around on mine, I could go 10 clicks without an issue, then I might see one of the following...
1. Complete freeze. The controls stop responding, until the unit is reset (this was the symptom, during my fly-away the other day).
2. LCD 'glitch'. The horizontal trim indicator becomes a messy, sometimes split, or otherwise garbled image.
3. Reboot. The unit acts as if the power has been cycled (or, as if that last click of the horizontal trim was a 'reset' button for the processor). The unit sometimes came back normally (though, of course you have to move all of the switches to their default positions). Sometimes, it would come back with an EEPROM error.
There is a 6 page discussion on the openrcforums which you can find by searching 9x reboot with horiz trims. By page 4, they've figured out the issue is with the incorrectly designed ground scheme. Page 5 includes a series of high res pictures and text, describing the fix.
Don't let the low price fool you! This is a quality transmitter! It needs a few tweak to make it awesome though. I modified mine with a rechargable hobbyking LiFe tx battery pack, backlight display, firmware upgrade to er9x, and a FrSky DIY Transmitter module. Takes about a day to modify it, but you will certainly get your moneys worth and then some.
Best valued transmitter on the market. I already have 3 of these, and many friends happy with theirs after I recomended as well. I bought this one to try out the ER9X firmware conversion.
I've never had a glitch nor a failure. Order the Turnigy TRX 2.55 3s and you will fly for months without a recharge. I also add the backlight to all of mine. My favorite color is the green, it stands out the most.
