LES Douglas DC-3 v2 - brakes problem

[Max2307]

The YAW axis works correctly when assigned and responds as expected. However, the differential brakes are not working.

When I press the right or left brake pedal, there is no response at all.

The only way braking works is if I assign a button to the brake command, and in that case braking functions correctly. Unfortunately, without working differential braking, ground handling is basically impossible.

Thank you guys

Apologies for the late reply.

I'm working on a large update for the DC3.  I'll make a note of this and address it.

@Max2307 Just a heads up.  Confirmed.  This is a bug.  When the "Rudder Controls Differential Brakes" option is enabled in DC-3 Settings, the code overwrites the toe brake axis values every frame, even when the rudder is centered. That zeroes out any input from your brake pedals, which is why the axes appear completely dead while button-bound commands still work.

As a workaround until the update: Open DC-3 Settings, go to the Options tab, and uncheck "Rudder Controls Differential Brakes." Your toe brake pedals should work normally after that. You'll lose the rudder-to-brake taxi assist, but you'll have full differential braking through your hardware.

The fix is already in for the next release. The differential braking option will no longer interfere with toe brake axes. When the rudder is centered, your pedal input passes through untouched, and when the rudder is deflected, the two inputs are blended rather than one replacing the other.

as of v2.0.2:

"Toggle brakes maximum" always works to set and release the parking brake.

- if you have the "Wheelbrake" axis assigned, it is the only thing which will control the brakes - differential braking is not possible

- otherwise, if you have "Rudder Controls Differential Braking" enabled, it will control differential braking - any rudder input will proportionately brake that wheel, and the "sensitivity" scales the proportion. 1 means full left rudder = 25% left brake, 4 means 100% left brake. The "Hold left/right brake" commands won't work and nor will the left/right brake axises as Goran's said. "Hold brakes regular/maximum" will work but with a gradual fade-in over a second or two. "Toggle brakes regular effort" works normally and instantly.

- with "Rudder Controls Differential Braking" disabled you can use left/right brake axises and also the "Hold left/right brake" commands, but they also have the gradual fade-in effect.

It took a frustrating hour or so to figure it all out but now I (no toe brakes, normally a single wheelbrake axis on the stick) am very happy with the "Rudder controls..." setup and looking forward to slinging four tonnes of cargo and appreciating the ortho scenery
