Which Way Changing Contact Points?

[Devildog73]

Okay guys,

This is KM's P40E at Calais, France.

Which way do I adjust the contact point numbers to get my wheels out of the mud?

Thanks,

Lee

Lee,

One of the things we've done is to create a general information / tweaking thread. What you are looking for has been discussed: http://www.sim-outhouse.com/sohforum...g-thread/page3

Begin with post #44 and work your way through. There's an attachment by Captain Kurt that should help.

P.S. - I was going to respond with "push the throttle in," but I figured this was more helpful.

ROFLOL!
Hey, sitting at home gaining weight.
What else do I have to do until the world comes to our senses..........

go to the [contact_points] section in your aircraft.cfg folder: (save a backup copy first). The first three lines are the landing gear. The 1st point is your tail wheel, the 2nd and third are your two MLG. The numbers in each line contain these elements: (they are relative to the reference point in the weight and balance section)

1 (1)	Class	Integer defining the type of contact point: 0 = None, 1 = Wheel, 2 = Scrape, 3 = Skid, 4 = Float, 5 = Water Rudder
2 (-18.0)	Longitudinal Position	The longitudinal distance of the point from the defined reference datum (feet). Positive is forward (out the nose).
3 (0)	Lateral Position	The lateral distance of the point from the defined reference datum (feet). Positive is starboard (right, as viewed from the top with the airplane pointing “up”).
4 (-3.35)	Vertical Position	The vertical distance of the point from the defined reference datum (feet). Positive is up.

Gradually decrease the vertical position in short increments to the MLG, save the cfg file, reload the airplane and take a look. A pain in the neck, be patient.

Okay,
Here is the original:
[contact_points]
static_pitch = 16.27
static_cg_height = 5.58
max_number_of_points = 7

point.0 = 1, -15.9, 0, -2.1, 3200, 0, 0.5, 45, 0.36, 2.5, 0.9, 4, 5, 0, 155, 250
point.1 = 1, 1.2, -4, -6.4, 2200, 1, 1.35, 0, 0.5, 2.5, 0.86, 7, 3, 2, 155, 225
point.2 = 1, 1.2, 4, -6.4, 2200, 2, 1.35, 0, 0.5, 2.5, 0.86, 7.5, 6, 3, 155, 225
point.3 = 2, -0.0377, -18.7117, 0.8316, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 5, 0, 0
point.4 = 2, -0.037, 18.7018, 0.887, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 6, 0, 0
point.5 = 2, -20.0477, 0, 0.9725, 2400, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0
point.6 = 2, 7.6082, 0, -1.629, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 4, 0, 0

Here is what I changed it to:
[contact_points]
static_pitch = 15.39
static_cg_height = 5.69
max_number_of_points = 7

point.0 = 1, -15.9, 0, -2.1, 3200, 0, 0.5, 45, 0.45, 2.5, 0.9, 1, 4, 0, 200, 398.935
point.1 = 1, 1.2, -3, -6.4, 2200, 1, 1.35, 0, 0.64, 2.5, 0.86, 5.5, 6.5, 2, 200, 427.429
point.2 = 1, 1.2, 5, -6.4, 2200, 2, 1.35, 0, 0.64, 2.5, 0.86, 5.5, 5, 3, 200, 427.429
point.3 = 2, -0.0377, -18.6562, 0.8315, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 5, 0, 0
point.4 = 2, -0.037, 18.6462, 0.9422, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 6, 0, 0
point.5 = 2, -19.902, 0, 0.8748, 2400, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0
point.6 = 2, 7.6082, 0, -1.629, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 4, 0, 0

Got the Starboard wheel on the ground!
I have no idea what you all are saying as far as the numbers.
I'm a visual learner.
Between Captain Kurt and Mike71, all I can figure out is the Point 1 is apparently the right main landing gear.
I have no clue which point is the left main gear.
I have no clue which is the tail wheel.
Which is why I posted the strings of the aircraft with original and changes I made, one of which actually worked.

[Captain Kurt]

point 0 is the tail wheel (0)
Point 1 is the left main gear (-4)
Point 2 is the right main gear (4)

These numbers define left/right position relative to the center line of the aircraft, not the height above the ground that the wheels sit on.

The wheel height is the next set of numbers after the left/right numbers. Adjust these numbers up or down until you are happy with the wheel positions. Point one and point 2 numbers should be the same as they are the main wheels.

Thanks, Captain Kurt,
I will play with them and see what happens.
