You need to wait about one minute before attempting to start.
I don't know if it's like that IRL, but same thing happens if you abort during normal start.
Your best indicator is to wait until RPM needle zeroes out.
 

No, but you can use 3rd party programs like voice attak or joystick gremlin to work around it.
Doesn't work for 64.

You need RAlt Home and RShift Home to jump from off to idle. Then youo can use Num or mouse to move levers.

As for tuning light, R-828 is broken now. Light does not turn on, but radio automatically tunes to selected channel.
As far as I can tell, you did everything right. Possible reason you did not get any signal is that for VHF/UHF, you need line of sight to the transmiter. You being on the ground will most likely prevent that.
One note though: if you are reporting a bug, try to make it as short as possible AKA in this particular case, put hot helicopter and put that unit right next to you, so people watching it don't have to spend time waiting for important part to happen. I wrote above about possible reason it didn't work out for you.

OK, I was wrong.
It is a SYNC mode. I've got exactly same behaviour as you. Just turn it off it via switch on the sight and you're good to go.

No.
But you can fire it yourself.

You need to bind this too.
You can use same bind.

In your configuration, only GUV will work.
Tip: when reporting a bug via track, use Caucasus map, so people that don't have one of pay-for maps can also check and help you.
 

That is your problem, you need to move them out of shut off detent
RShift+Home and RAlt+Home

It seems there is a problem with DL with cold helicopters.
 

It does not work if your scan is still active.
I used it yesterday.

Are you talking about this one?

 
Here is track file

Here is what works with what

You need aiming station tab

Kinda selfish of you to expect others to spend time you are not willing to invest yourself.
Anyway. There is no procedure for that in Chucks guide. You need to jump to front seat, switch weapons down, wait for 3.5 minutes, switch it back up (you can use Petrovich for that) and after it warms up should be good to go.
My guess is that you turned away before closing sight and Petrovich did not manage to do it in time to preven gyro toppling. Never trust Petrovich to do that in time. Close it yourself (well, tell Petrovich to close before you bank).

exactly. you need to select target first with short right (default keybind is D).
After that you do all the lineup/tone shtick and fire

Get him into hover, switch to HB mode and set 0 alt. It will take some time, but he will land

No, it doesn't work that way. You can't make it transmit text-to-speech, you have to select a file. It has to be either .ogg or .wav type of file.
Take another look at that video at 1 minute mark.

Probably some corupted file. Run full repair.

All of your points, except 3, are de-sync issues.
As for your point 3, 18000 ft is not a hard line with on-off state. People can pass out from hypoxia at a lot lower altittudes and they can stay awake a lot higher. 

If you are using buttons (instead of axis) to move TADS, at first it moves slowly then rate of movement speeds up. That slider sets how much that "speed up" is.

Go to Apache/A10 tab and click on modifiers on the bottom. You probaby added those as switches, not buttons

Your CPG should have his ACQ source set to PHS. He just needs to slave TADS and it will point were you are looking. But, you can't look away until he deslaves TADS

Ah, OK, I get it now. I don't use that button. When you start boresighting procedure, cursor will automatically position itself so you can just use cursor depress on your collective.
