So I have a button on my hotas for toggle reversers in the sim. This doesnt seem to work with the 737. Ive tried to sift through the manuals but couldnt find any info relating to this. Any tips?

The toggle reverser command in msfs works differently to previous sims.  It merely activates reverser mode, and then you have to push the throttle to actually reverse thrust.  It’s fiddly and I don’t like it.  I have my button mapped to reduce thrust,  which should push it back to reverser range and max it out, like the reverser button used to do in fsx.  My caveat is that I haven’t tried it yet in the pmdg, but it works for all my other aircraft.

That's it. I think it's called 'decrease thrust '. It works in the PMDG.

If you normally use a method of toggling reverse, then pushing your throttle forward to control how much reverse is being applied, you can still do that.  You need to use the "hold throttle reverse thrust" instead.  You'll have to hold down the button while pushing the throttle forward again, but it does work.  This is the method I use for all my planes with a Bravo, and before that with an easily accessible throttle button on my old X52.  Except CRJ which doesn't work with this method.

That’s what I realized after a bit of fumbling around. 

I toggle reverse thrust and push levers forward then back when I activate manual breaking. Needs some coordination but some people aren't that coordinated.

After first flight LOWW to LGSK I can confirm that it works... sort of.  reversers kicked on ok and slowed the aircraft, but pushing the throttle back forward again didn't disconnect the reversers, like it would on my other planes.  had to use the mouse to disengage.  will play around to find the best solution.

Until you get the mappings sorted,  press and hold F2 after T/D and then F1 to get back to idle. 

I find that press+hold and the use the throttle axis works pretty well. I mapped it to a button reachable with my thumb. Prefect. I prefer to the FSX/P3D way.

Hmm I might not have gotten enough coffee yet to grasp what you are saying to me. I have been using Toggle reversers in MSFS since launch, and I use it in airpanes like ie. FBW A320. I idle my throttles, push the toggle, and push the throttles forward to engage the reversers. I tried to do that yesterday on a landing (my first flight with PMDG 737 since P3D - so a few years actually), but instead of engaging the reversers, the toggle didn't seem to do anything, and when I pushed my throttles forward, the airplane would accellerate.

Strange. It should have worked, one would think. I have the same setup except I use the "hold" instead of "toggle" and it just worked right of the bat.

Now there's an idea!

The problem with just mapping a function to reduce thrust to engage the reversers is that you end up with reversers maxing out all the time. With the toggle function you get the granularity that you find in real airplanes, and you can do idle reverse ie.

Yeah, were we able to do this in p3d as well? Cause I was always saddend by how early my plane braked (especially say polderbaan EHAM, where the first exit is down the runway anyway). I love the idle reverse possibility!

This seems like perhaps a better option than the "reverse hold" binding to a button on the controller. But - is it possible to map F2 and F1 to a controller? 

I find the toggle reverse thrust like in the FBW worked a bit better.
