There are detailed instructions on the deviationtx website here:
http://www.deviationtx.com/repositor...y-to-Devo.pdf/

If you remove the module from a V911 Tx, it requires desoldering or judicious use of a hacksaw as well as soldering 5 wires. If you buy a module from ebay/aliexpress, it only requires soldering 5 wires. The solder points are very easy to hit (soldering to existing pins or pads).

Personally, I do it via wire-wrap which requires virtually no soldering, but you need to have the proper tools for that.

Hubsan X4 Transmitter stick calibration 101

*EDIT: Hubsan posted this Mode 1 Tx stick calibration video and this Mode 2 Tx stick calibration video.

Dbacon'a graphic of the stick calibration.




*CAUTION: If you have a Mode 2 Tx with the throttle on the left and you power on the Tx with the sticks in the upper and outward positions in as in the accelerometer calibration mode 1 video, the Tx becomes mode 1 with the throttle on the right. You can set it back to mode 2 or visa vesa by using the instructions below or the video for the accelerometer calibration mode 2 Tx power on procedures. If you accidentally set your mode 2 Tx with the throttle on the left to mode 1 and bind the Tx and X4 and pull the mode 2 right stick down, it will arm and the spring will bring it back to the mode 1 throttle at half power and the X4 will take off. This caution also applies if you have a mode 1 Tx with the throttle on the right and mistakenly use the mode 2 Tx calibration procedures. In that case use the Mode 1 calibration procedures to correct it. Be careful!

Note: Resetting the X4 Tx sticks using these calibration procedures will also reset all the trims to their neutral positions. The neutral positions can also be found by the indicator on the LCD and a beep when they are in the neutral position.

Gents,
Yahoo! This got both my Hubsan X4 Tx's working OK again!

Note: These instructions are for the Mode 2 throttle on the left Tx which is the only version I have and use. The Gents with Mode 1 Tx with throttle on the right will probably have slightly different instructions, so post those when you figure them out. Hopefully these Mode 2 Tx instructions will help you understand the Hubsan Tx stick and trim switch calibration procedure.

Here is what I have found that will work so far to calibrate the Hubsan X4 transmitter sticks if required:

1. Press and hold the throttle(left) stick in and then turn on the transmitter. You will see all the icons in the LCD on and the number 188. Release the throttle stick
2. Press the throttle(left) stick momentarily and quickly in while it is in the full down position and the LCD will display 0.
3. Momentarily and quickly press the pitch/roll(right) stick in, roll(right side horizontal rocker switch) trim button left, pitch(right side vertical rocker switch) trim button down, throttle(left side vertical rocker switch) trim down, yaw(left side horizontal rocker switch) trim right.
4. Press in the throttle(left) stick momentarily and quickly and the LCD will display 100.
5. Rotate the pitch and roll(right) and throttle(left) and yaw sticks fully in a CW and CCW rotation for at least 2 times each way. You can rotate them simultaneously or separately as it will work either way. Momentarily press the pitch(right side vertical rocker switch) trim up, roll(right side horizontal rocker switch) trim right, throttle(left side vertical rocker switch) trim up and yaw(left side horizontal rocker switch) trim left.
6. Press and hold the throttle(left) stick in for at least 2 seconds until you hear a beep. At this point you can move the throttle stick up and down and the LCD should smoothly display 0-100.
7. Power off the Tx then power it on. Power on the X4. Carefully do a hand test to make sure the pitch, roll and yaw and throttle sticks are working normally.
9 .Have fun and fly safely!

Nice, do you know if its possible to extract the module from the hubsan tx or should i just order from ebay?

Yea I know we men have this measuring problem

Even though I live in Texas, instead of reckoning, in order to get accurate measurements, I attached a stripped 2.8g EagleTree altitude microsensor logger and sent the X4 straight above me at 3/4 throttle until it lost control and started falling and required the signal and leveled. I then repeated with the Tx oriented flat, perpendicular, sideways, in front of me and again repeated the tests held over my head. The highest measured altitude achieved straight above was 127ft/38.7M. That is actually pretty good for 2 printed circuit antennas and a ~3mw Tx.

Now about the size of those...trees...

Jim

You my find this interesting then!
150meters = 492 feet, I'd say that was much closer to my 500-600ft then your 127! Maybe yours is faulty? Shall we re-visit them sizes again
These specs are on many websites (just before you say they have ft and meters mixed up), but Amazon is well known!

There is no module in the hubsan. it is implemented on the board. It also has no power-amp, so range is likely quite low.
you can get a low-power (xame range as hubsan) version of the module by searching ebay/aliexpress for 'XL7105'
You can get the high-power/long-range version by searching for 'a7105 500m'

Good to see you've figured out what that menu was I was wondering what had happened with my tx. Only calibrated throttle previously and the x4 went all over the place. Giving this a go when I get home.

Shhhhhh, even though it's a fake antenna, mine is rotated up before flight, because it makes the controller not look like a toy ;P

T,
Not really interesting to me because that is also not correct information from some Amazon poster. A range is not even mentioned on the on the Hubsan X4 website, or anywhere in the X4 manual(attached), or even in the clone Traxxas A1 Specs.... For the X4 any range above 150feet/45M is simply not possible even under the best propagation conditions with the X4 Tx and Rx. I only trust and report what I actually have and accurately flight test.
Cheers,
Jim
