Throttle Cut should act on an output channel instead of cutting the throttle stick input about er9x HOT 7 CLOSED

Actually I wanted to propose this as an enhancement, not a defect...

In order to cut only throttle you can do this:
MIXER:
CH3  100% THR !TRN
    -100% MAX  TRN

What this does is give CH3 input from the throttle stick when the TRN switch is 
off (towards you) and -100% when the TRN switch is on.

Actually here is my CH3 mix:

CH3 100% THR ID0 c1
    100% THR ID1 c2
    120% THR ID1 c2

with c1 curve:  -100    20  30  50  80
and c2 curve:     80    50  30  50  80

If I just add "-100% MAX  THR" to my mix, it just doesn't work.
That's where my suggestion would be much easier imho.

OK, I see what you mean.  
I'll see what I can do about it.

Added an option to specify TCut target.

Works great, thanks a lot for all the great work you're doing !

In the heli world this is called "throttle hold percent/value".
