Here is reverse thrust. “Neutral” is all that is needed to make this work. Ensure physical levers are at their idle position, then adjust Neutral so that the white dot appears on the centre line. If in doubt have it very slighly lower than the centre line as that will stop you from accidentally going into Beta.

Propeller reverse thrust set up

These are bindings I am using: [image] The bit that makes it work is on the sensitivities interface: [image] The “Neutral” setting specifies the point where you cross into reverse thrust. My TQ6+ has a detent for idle, so I simply rest both throttles at this detent, then adjust the “Neutral” point so that the dot as shown above rests on the horizontal line. Forward thrust is below the line, and the steeper curve above the line is reverse thrust. No button necessary, and you can alter the…

Prop feathering I get SPAD to do the work.

Virtual Fly TQ6+: Prop feathering

This is what I did: [image] Because the Axis only goes from 0 - 100, with no negative component, the sim can’t do this natively. So when the prop lever is fully aft, it is at 100. Spad detects when this is at 100, waits 100ms (which was the “magic” bit to make this work, then sets the “PROP_PITCH1_SET” to 4294963200. This is the number you see that variable get set to when fully feathered with the mouse.

Essentially the physical lever will go from 0 to 100, with 100 fully feathered. But in the sim it actually goes from 100 to -25, which is feather, and since the prop axes has no negative range you can never fully feather. SPAD detects when the physical lever is at 100, then sets that simvar to that really high number, which actually equates to -25 in that other simvar. Trying to manipulate that simvar directly this way doesn’t work, but this does. The 100ms delay was necessary as it would sometimes fail to go into feather, and this makes it reliable. For twins, have the same setup but for the the other axis, and the other simvar, so:

For condition, I just use the bog standard mixture axis:

The works for both pistons, and turboprops. From idle cutoff, as you advance the lever forward nothing will happen initially, but then at a certain point it will pop into lod idle. As you advance the lever further forward, again nothing will happen until another point is reached, then it will go into high idle.

I haven’t measure it exactly, but I would imagine its probaly 0-30 for idle cutoff, 30-60 for low idle, and 60-100 for high idle. There are some tiny differences per plane. For example, in some I have to bring the mixture lever back past the idle detent that exists for all 6 levers to go into cutoff. But in the Shorts, the idle detent is actually cutoff. It’s so exact I wonder if BBS used a TQ6+ during development.
