10+years all good but...... it finally happened. Free fall outta da sky from200' ...possibly GiFi battery only thing i can think of

I feel for you because I lost an H after putting in a new gifi and the bird exploded not long after take off. I also remember ateve saying that can happen if the battery isn't put in far enough but I always check that carefully. Dunno what except a bad battery.
I saw it not wanting to put one cell up to 100 but I just blew it off..i think it was like 100 99 96 100 tried several times but never would balance....it started out with one really low. I may take a harder look at the battery...I think that is what did it...
 
GPS lost is a result of the crash not the reason. Battery volatge is good all the time. The problem is the motor-stop command sent to the drone by ST16. From my point of view this was not the red button but a defect throttle stick. This is clearly seen in Remote_00169.csv
CH0 (trottle) and CH1 (roll) should have 2048 in neutral (middle) position - they don't have.
CH0 should never go below 683 (-100%) when the red button was not pressed but it does.

What FW version do you have at the ST
 
st16_system_v03.01.b30
apk v01.00.45
Another reviewer messaged me pointing out there is no direct signal the red button itself was pushed. This is where the smart guys help out.

Could just be corroded pots on the controller. Can you check the Hardware Monitor on the ST16 and tell us what you see for stick J1?
I checked and they appear fine...usually if one needs cleaning you can thump it and it will come back and not be perfectly centered but they all did fine.. It probably hasn't been too long since they got shot with electronic CCeaner
 
Oh, there is an indication of sending the motor cut signal to the drone but not by red button, probably.
For me this looks like wrong channel settings, or probably a defect throttle stick. The Throttle signal has -130% sometimes which is not normal.
The -150% (or 0) lasts more than 3s and the flight controller stop motors as expected.

Channel 1 (roll) is also not centered.
Does it automatically shut off the motors if you hold the throttle all the way down for xx seconds?

No. Not normally. Unless there is a hardware problem or some sort of firmware issue.
You can do a quick look using the "Final OutPut display". The output display is a "secret button" feature that is turned on by doing a quick double tap of the flight battery voltage icon. A whole double row of 24 "scales" will appear. For this, you only care about first one, labeled "CH01". "CH01" is controlled by both the throttle and the "Red Button".
Once the display is up:
1.) Hold the throttle stick full down. Look at the NUMBERS at the top of the CH01 scale. The numbers should not read below 0%.
2.) Release the throttle stick, then press the RED button. The numbers above CH01 should read-25% (25% below zero). If not, let us know what it reads.

red button takes it all the way down and the stick takes it down about 80% of full down(red)
 
Try holding down the throttle stick while you tilt the stick to le
stick takes it to 008%, up 97% , and red -25% centered at 52%
Those are pretty normal.
Try this. Hold the throttle stick full down. With the stick full down, move it sideways back and forth to see if CH01 moves.
Then repeat with throttle full down, moving the right stick around.
CH01 scale should not move in response to the other sticks, but there are issues that can make that happen.

Something is not set up right my pan is moving the throttle and the camera switches on the left are also moving the throttle as well...........

It sounds like someone has been in the channel settings and you have channels "mixed" (cross linked". Open "Channel Settings" at the bottom of the screen. Do not touch anything. In the array of boxes on the left, ONLY J1 and B1 should be lit. It sounds like at least K1 may also be lit on yours, maybe others.
Again, DO NOT TOUCH ANYTHING in channel settings.

channel settings must not be exclusive to each model? I loaded up a new model and it still has the pan as the throttle Somehow K1 got mixed into the throttle J1

It was mixed in....I wouldn't normally even go to that page..I don't think i have ever even opened that menu....funny in hardware monitor it appeared to be fine....I have no idea how it got put in there

Somebody may have played with the controller at some point. The charts look like moved the pan during ascent, which biased throttle. When you started down, it was probably coming down a lot faster than normal, and at some point the Throttle stick plus the bias from K1 put you at the motor stop point. Other guys can probably explain it better, but this quick combination of charts might show it.

You should completely delete that Model, create a new model, and see if K1 is Mixed in on the new Model channel settings.
I generally do a factory reset, but that's considered over-kill by some.
 
I did create a new model and it came back the same channel problem(s). not sure why. I would think they are exclusive to the model loaded at the time?.....factory reset ? default to firmware#? and then upgrade to firmware# I have another st let me look at it too and see if it happens to be hosed as well

just deleted all the extra models and made a new one and it's still pan/throttle messed up so....I can't bind it. but that shouldnt matter. Have no idea how that would be coming through unless there is a global channel map for the internal H....I didnt do the 920 either ...Unless someone switched the icons
 
You might try a factory reset to see if it clears a glitch somewhere. The mixing is all logic and firmware as far as I know. I don't know of any hardware malfunction that would be causing it.

Was the other ST16 OK?

If you created the new models by making a copy of the permanent Typhoon H Model, it may be the K1 is mixed in on the permanent model. That would be one possible explanation, anyway.
You can select the permanent Typhoon H model on the Model Select page, and then use "Channel Settings" to see if K1 is mixed in with throttle and red button.
If K1 is mixed in on the permanent TH Model, you will need to do a full factory reset to get rid of it.
