This is how to update firmware for 4in1 modules. I own 2 types at this time.
Since there are several modules and a few ways to update I will try to cover what I know and I hope you will help. My goal is to try to add whatever helps to have a step by step approach to do any type.
For reference I followed Pascal Langer's process. HERE:https://github.com/pascallanger/DIY-...iling_STM32.md



T-12 4-in-1 V 1.2
Since I was first successful with this one I will start here.
The version should be determined first.
AFAIK there are currently 2 versions of the PC board. V1.1 and V1.2
I had to open the case to determine my PCB version.
If you don't have to remove the PCB coax connector then don't. These types of connectors can give out after a few disconnects and re-connects.
The V1.2 already has an active mini USB port and it can be updated via that port without any jumpers or soldering.
The only tool I used was a miniUSB to my windows 10 PC
Plugging into this port activates the Boot 0 and makes it ready to update.
My 4in1 showed up in my device manager as Silicon Labs CP210x USB to UART Bridge (Com6)
I was able to upload the new firmware with the module out of the TX

I started with the Pascal's Preparation step and followed every step
Install arduino ide, upgrade Java, follow the downloaded the multiprotocol source by clicking on the HERE in step i.........
When I got to the upload step this is whatTools looked like just before UPLOAD.

My goal is to update the firmware, and add a multi protocol module.
BACKGROUND:I recently purchased this working TX from an auction. I already owned 2 older 9X, 1 Turnigy and 1 frsky. I decided to try to do a firmware upgrade and after lots of research and you-tube videos (mostly quite old ones) I decided to document these adventures for 2019.
#1 what firmware to use:
This TX came with it's original Turnigy 9x software.
I very much like OPEN-tx (thanks to you-tube edu-macation by R Scott Page) which I have in 2 current radios. A Jumper T12 using a modified version called Jumper TX and a new for Christmas Taranis QX7s. As I now understand https://www.rcgroups.com/forums/atta...d=11564993only an older version 2.0 Open-TX would work on this older radio. Another choice, an even older OS as OPEN-9X.
Since I've been reading about an alternative ER9X and the work of Mike Blandford I decided this will be my go-to first attempt.
Mike also has a version of ER9x that seems to support the T-12 too.

#2.Here are the details of how I went about getting this working.
I purchased a USBasp board from a local US ebay vendor for around $4.click here for my E-BAY link
I could have got it cheaper but CA to AZ was quick for a little more.
I also purchased a 10-pin to 6pin adapter for $.99 click here for E-bay link
When I attempted to use this USBasp on my windows 10 computer it did not install correctly.
Research pointed me to This Zadig website for the correct drivers.
Following the install...Continue Reading

Well, I just got the Jumper T12 with the multiprotocol Module. I was able to get started in only the simplest functions. I'm reading posts, taking notes and watching Youtube video but I have a lot of questions and I don't see or understand the answers. I'll try to ask and take questions and post answers in this original post/blog. I'll even break down the points I've already learned below or direct you or I to a video or post with the answers or details. I'll see how it goes from here.

I just got my T-12. Excited to see how I can use it for different aircraft.
I just got a Syma clone X5C-1 to respond to Bayang setup and even got a switch to act as MOTOR ON-OFF.

I will add to this as I learn more.
Very cool.

I finally went to leaders hobby and purchased the 9x.
http://www.leaderhobby.com/product.asp?ID=9394001220239
I purchased mine from leader because I wanted to try different modules and I did not want to cut the antenna wire which was required of the HobbyKing Turnigymodel.
I have been using the standard firmware.
So far the only problem has been the top line of the display is OFF (deffective). It does not light. With the standard firmware this has not been a problem.
__________________________________________________ ______________
My first mod was to add the backlight.
I ordered the green from HobbyKing. http://www.hobbyking.com/hobbyking/s...dProduct=17128
I chose green because it seemed to have the best contrast for me.
I followed the instructions on Youtube from foamfighters and HobbyKing.
HobbyKing - Quick Guide: Install Back Light on Turnigy 9X (3 min 28 sec)
I had 2 problems with this video.
1. the foam pad at time 1:15 was really hard to remove. I used my heat gun to warm it up and it came off much better.
2. my backlight wires locations made it difficult to miss the switch as shown at time 1:50. I had to bend mine and I have heard that some have ripped off the led and had to glue it back.
I also decided to remove all the connectors to work on the board away from the tx base.
I'm satisfied with the results, the backlight looks great.
__________________________________________________ ______________

My next mod will be to add the ability to change the program. I ordered the programmer and some pogo pins from ebay.I wanted to leave the pogo pin link but my supplier is no longer showing any items. I do hope I get my parts. The programmer I ordered is this one:
http://www.ebay.com.au/itm/180768377568
I have also reviewed this video on Youtube on how to wire a programming connector. I need to verify this is the same for my radio.

Once apon a time. This past week.
I decided to fly my 4 year old, 16 oz. UltraFly Furious 3d foamy bipe at my son's house. MISTAKE!
Went up over a very old, big, high tree, the wind caught it and I lost sight of it knowing only the direction it was headed, I followed. Suburb residential neighborhood. Older homes. Toward a main street, considerable traffic.
Cut the throttle, kept looking in it's last known direction. More trees but shorter. Started walking that way, didn't see it then I thought I saw something, maybe it, go down behind a house 3 houses down from my son's. Now I, my son and one of his friends started a grid search. Looking in yards, sheds, roofs, trees and in a heavily forested lot. Playing with the throttle from time to time, hoping to hear something. After about 30min. I thought I heard the growl of my motor changing with the throttle on my TX. Didn't sound good but the battery was still attached. Yes, I found it, well sort of. I was in an alley, next to the local pub. The motor noise was coming from a flat roof of a 3 story commercial/residential building that faced the main street with the traffic. I called my son over and we all listened. He was about to get a ladder. I played the throttle and the plane prop became visible at the edge of the roof.
It crash landed, on the roof, upright, facing the edge and I flew it off, dropping to the empty lot next to the corner pub. Prop damaged, shaft a bit bent, lost brace from top left aileron to the lower wing and a few glue cracks, but I had it back.
And we lived happily ever after.

Isn't that amazing?? I'm REALLY glad I go to church EVERY week.

I just received 2 HobbyKing Spektrum compatible Rxs.

What I first noticed.
  • They had no covering, just a pc-board.
  • The antennas are just wires, not coax.
  • Some of the solderjoints on one, near the servo connector needed additional solder.
  • The antennas needed a bit of glue support so they wouldn't break from use.
  • There were no instructions.
I decided to wrap the body with heat shrink tubing which will protect the circuit and give me a surface to mount
my velcro adhesive. They are designed so the RX status LED is at the top so you can see it if the heat shrink goes up to, but not over the antennas.
There are some pictures in the FILES section at the bottom of the ad which showed me the proper connections.

The bind process or bind procedure:
1. Plug in the bind plug to the BAT connector.
2. Plug in the batery to any other position.
negative closest to the PCboard level.Black wire(Futaba), brown wire (JR)*
the RX status LED will begin to flash quickly.
3. Lower the throttle on the TX to set the throttle cut failsafe.**
4. Hold the bind button on the TX and turn on the TX power.
5. Let go of the bind button as soon as the RX status LED goes OFF.
Wait for the RX status LED to come back on flashing,
then wait untill it goes out and comes back ON SOLID.
6. Remove the battery plug from the RX.
7. Remove the bind plug from the RX.
8. Power off the TX.
bind is complete.

  • When I power up the RX with the TX OFF the status LED will blink and go out. A few seconds after I power up the

I took a pass at the last notification to buy the Turnigy 9X when they were in stock.
Several guys have reported that their sticks are requiring service/cleaning.
If this radio does not use quality pots then I'm concerned that a purchase would be a waste of money.
Am I overreacting??

I'm going to gather data from OWNERS of the various 9X transmitters and modules.
I'd like to build some sort of matrix that I hope will tell me the best brand, version, time, parts to purchase as I am not yet a 9X owner.
I will try to gather this data from several of the threads and I also hope that owners will leave their information here for me to add/edit thereby try to keep this thread on topic and as clean as possible.
Also if I make a mistake or improper observation please bring it to my attention.

I think that the first task I have is separate the TX /case/base from the TX module.
I base this on the fact that the basically $9 RX will be a sufficiently satisfactory item to purchase.
I will start by gathering the brands of receivers that will work together with the common TX module.

IF this ~$9 RX proves to be unsatisfactory then a replacement would be in order as it looks like other TX/RX module combos can be used as replacements.
THEN the data gathering will then move to the TX case/base and it's new and ever-changing firmware.

Another reason I want to start here is that there are modules that can be adapted to be used with other TX case/bases.
-------------------------------------------------------------------------
Compatible RX choices.
Since the current RX version is V2 I will use this as my base.
(If there is a v3 upgrade this data may be in jeapordy.)

I range tested my system today.
An associate operated the TX on the road near our field.
I drove my car down the road.
Line of sight on this road gave me .5mi and full control.
I did loose signal when I lost line of sight due to the dips in the road.
I couldn't get any farther as on this road it was from peak to peak.
I will try to go a longer distance when I find a better road.
I could barely see the associate at this distance so my foamy plane would be just a spec.

I find these systems to be a fantastic value. I know there are variations but I'd like to keep the topic only on the identical looking 6 channel systems and the same 6 channel RX with the satellite RX and where you can buy them.
Only those that are programmable via your PC using what is called the t-6 config utility. I also want to note any differences and RX failsafes (no TX signal)

The main thread with lots of information and additional transmitters is HERE

So lets get started.
EXCEED Xheli.com - hobbyparttz.com - nitroplanes.com
FAILSAFE (my 2 rx) of neutral on ch4 and ch5. All other channels have no signal.

HOBBY KING hobbycity.com NO LONGER COMPATIBLE, NOW V2
V2 is a frequency hopping system and requires different RX. You can read more about V2 in RCGroups thread here

FAILSAFE JULEZ reports that " My 2 HobbyKing RXes give out no signal at all pins."

FLY SKY rcmodelparts.com NO LONGER COMPATIBLE NOW V2 (B)
enjoyhobbies.biz - snhobbies.com TX only -snhobbbies.com tx&rx

Elite-6 centuryheli.com

TUBORIX r2hobbies.com NO LONGER COMPATIBLE NOW V2

FAILSAFE JULEZ reports "Well, my Turborix RX gives out no signal on #3 and centers all other channels upon loss of signal."


Please feel free to comment or add to this. I will add your info to the main post and log the changes.
