Difficulty with spit on ground

[Wacko_ZA]

HI guys, im having some serious issues with the bird on the ground, i have not set my rudder rates etc. i have the saitek combat pedals and x55 stick and throttle. can anyone give me a indication of where to start?

much apreciated!

What are your issues? I have a few issues on the ground so I am curious about what yours are.

[NeilWillis]

The issues you have on the ground are probably due to over-correction. You have to remember with all tail draggers that the centre of gravity and main leg positions mean the aircraft is very prone to ground looping, so you need to keep the aircraft slow, make very careful inputs to initiate turns, and when the plane starts to wander, correct quickly - again with small inputs. When you apply the brakes, the longer they are applied, the harder they are applied, so dabbing is better than holding.

 

The curves won't make any difference if you are over correcting.

Thanks neill. Yea its constant ground loops, serious issues taxiing and it wanting to f off to the left on take off even with full right rudder applied. Its getting frustrating!

I have set a button ( button 1 ) on my TS16000 to the brakes. It's not an analog axis, but works and if you give brisk presses it emulates not using the one in the real aircraft down to full braking force.

 

Together with gentle, but effective rudder inputs it is easy to steer.

 

On takeoff, full stick back, full prop RPM, advance the throttle until you get Boost of arounf 8, and gentle but effective rudder dancing at the begining of the takeoff run. Using neutral or a bit of nose heavy trim helps ( nose heavy trim is indeed what is recommended in the POH ).

 

The undercarriage is even worst than the 109k4 one.

Easy..easy. i had issues too in the first runs. Be gentle for the spit, she is fragile. Handle with care. read the manual. :D:pilotfly::book:

[NeilWillis]

Gentleness is definitely the key - just like a highly strung race horse. Modulate the brakes using an analogue input, and things are easier. With a digital wheel brake control, be aware that the longer you hold the button down, the harder the brake is applied, so dabbing the button rather than holding it down will help. Slow the wheel rather than locking it up in other words.

Put brakes on an analogue input, on the little slider on the throttle of the X52 it's way better, still hard, but with 20% brakes you can taxi without massive issues

He has an X55. There is no analog slider on the throttle.

I use the warthog paddle I know its no help to X55 user but it is still only pressing a button, just release often to save brake binding. I tried the slider in axis but was unable to assign it for some reason.

Reduce propeller RPM help, but caution to don't overheat the engine if reduce much.

+1 keep the rpm lever set to about 50%

thanks for all the help guys, i currently have the brake set to both my pedals, that is just a horrible idea, tried it on the joystick with a button, getting a bit better...practice is key i guess....

[Archaic]

Are you guys using automatic or manual radiator control?

[razo+r]

Mostly Automatic

I found my best option was to use the slider throttle on my TS16000. I also use the HOTAS unit of an old broken X52 for the throttle, prop and other functions...

 

But operating the brakes with the buttons in DCS is not, IMHO, so well implemented as in my other sim where the VVS fighters all use the same method, but it's more natural there even without an analog axis...

[Pikey]

Paddle button is best, you watch the brake lever, it doesn't fully apply unless you hold it in for a second, so you can dab the brakes, which I found easier than setting one of the toe brake axis. You cannot really taxi like it was an emmergency, has to be done as if you are 100 years old else you get into issues. Setting a little brake pemanently sounds like you will over heat the engine on the ground, just use throttle to get it moving, no need to use it much.

On X55, for all aircrafts that use a braking lever (L39, Mig21, Mig15, Mi8, and now Spitfire), I put the braking axis on one of the thumb rotaries, the down-most one, on the throttle. It get natural pretty fast, full rudder deflection right or left, and you control the amount of turn through more or less press of the brake lever.
