Differential Braking

I have tried mapping an axis to the toe brake, however I have to say that having mapped a digital button works a hell lot better on my joystick. It is a paradox but a digital button resembles also a lot more how the system operates RL. If you press a foot for a brake it will never be as quick and precise as when you operate the lever with your hand IRL (I tested it), therefore in my opinion putting the brake axis on a toe brake is counter productive and makes things much more difficult than in real life. I can taxi L-39 with digital brake absolutely precisely without problems, with the toe brake I am not able to do it at all, or very sloppy. Of course the best solution would be to have an analogue brake lever on the stick.

VJS161_Fire's suggestion sure worked for me! And that nose wheel thing was making me crazy. Also, now I finally have a use for that X-52 Pro slider. :)

If you read the extract about how the braking is applied after the rudder bar is pushed, you will see that using minimal application of the brake lever is what modulates the steering. If you use a digital brake actuator, it is purely 100% off and 100% on. Using an analogue axis, wherever it may be - the slider that replaces the friction control on the Warthog HOTAS throttle for example, or the toe brakes if you have a good set of pedals - gives you a lot more control over the brake pressure applied, from 0% all the way up to 100% in as many increments as the resolution of the axis allows.

No way will you get the same level of control using a digital input.

As on the P-51D there is possible to set "Take-off assistance" there should be "Taxi assistance" for the L-39C. Or just supply nose wheel steering as an option.

You might have a point there HiJack. There is always the option to start a mission on the runway, ready to take off of course.

But where would the fun in that be? Ask any rodeo rider if they'd like to ride a broken horse.

I completely agree that you will never get the same level of control using a digital input like an analogue. However even when you use digital input, it does not work like no brake (0) - brake (100). When you press the digital brake it takes some 2 seconds to go from 0 - 100. So if you briefly tap the digital control you can simulate light press on the analogue brake and it goes to around 20%, if you hold the digital brake longer it simulates full push. I can steer the simulated L-39 this way absolutely precisely without any problems probably it is even more comfortable for me than having it mapped on a toe brake. Having it mapped on an analogue toe brake differs much more from real life than having it mapped on a digital button on the stick, as far as my RL experience goes.

That's interesting, I was unaware of that.

Good to know, thanks.

Interesting about having to turn rudder so hard initially. I use the handle on warthog stick for my brake seems to work ok :)

Yeah... me too! :music_whistling::thumbup:

I had a spare pot-meter in my desk drawer. I bolted it under the handgrip, soldered some wires and spring-loaded the pinky paddle. Now it works exactly like the brakes on the L-39 (or the other russian aircraft:))

Cool mod!

I have bought a MC clutch handle and a load cell from ebay. Will hook that to a Bodnar LC board and see how that works...
