Differential braking..?

[RobdeVries]

Hi there,

 

Small question(s) while learning to control the BS. While taxiing I noticed that there is no differential braking, only the (Crtl-)W braking and Park Brake (PB)?

 

I have a CH Rudder and it would be nice to use the toe brake(s)

 

Another one related: the castoring front wheel, why does it castor to the left (or right) when standing stationary with either engine on/off and collective fully down. Does it have some kind of brake to stop the front wheel from castoring? Or do I use the PB for that.

 

Bit silly questions I guess but I'm a longtime MS FS9/FSX flyer so these little sim details matter to me :music_whistling:

 

Thanks in advance,

Rob

The nosewheel is steerable and therefore isn't castoring, but will self centre I believe.. Not sure though. The reason you'll notice it turn and if you switch to an external view you'll see your rudder has turned too is because of the autopilot. It seems to want to turn you onto heading even while you are on the ground...

 

At least that's my take on what you're seeing...

For the brakes - I think the brake lever is on the cyclic (hand operated) and there's only one which would imply that there is no differential braking in the KA 50.

This is correct.

The nosewheel is castering and not steerable.

So why does it turn if you are stationary? Is that a bug?

 

My experiences of castoring nosewheels have always seen them stay perfectly still unless I am moving....

I have CH rudders as well and I set the right pedal up as a toe brake.

Nope, that's a feature. Selforienting gears are little obstacle for non-centered pedals. The reason why it turns even when you're stationary is that your pedals are not trimmed in the neutral. Even with parking brakes ON, pedal input is able to turn the nose gear. Tested IRL with Ka-32 which has even 2 nose selforienting gears.

 

And yes, there is no differential braking on the real thing.

Thanks guys your answers are much appreciated and lluminating :)

Really, didnt know this! This bugged me like hell when trying to film the KA-50 standing still without the wheel turning :D :P

So how can it be castoring if pedal input has an effect on it? Lost in translation maybe?

[AlphaOneSix]

It castors freely, and self-centers. Pedal input affects it in that it will yaw the aircraft, turning the nose, and the wheels will castor to line up with the turn.

[Zorrin]

Must've misread it then, I assumed (yes I know assumptions) that it was meant it was linked directly and not indirectly through the differential torque. Still stuck in plank mode and forget the helicopter intricacies at times!

[RobdeVries]

More important perhaps, can it be solved with our peripherals like twist sticks or in my case (CH) Rudder pedals because it causes an inherent instability while on the ground.
