Carenado Cessna 182Q contact points question.


Double J

Recommended Posts

I have the 182Q AC and I just noticed the right wheel doesn't spin under 15knts while taxiing. I know it's a contact points adjustment. Any ideas as to which one needs to be adjusted.

 

Current config.

 

[contact_points]

static_pitch = 3.82

static_cg_height = 3.22

max_number_of_points = 9

 

//0 Class

//1 Longitudinal Position (feet)

//2 Lateral Position (feet)

//3 Vertical Position (feet)

//4 Impact Damage Threshold (Feet Per Minute)

//5 Brake Map (0=None, 1=Left, 2=Right)

//6 Wheel Radius (feet)

//7 Steer Angle (degrees)

//8 Static Compression (feet) (0 if rigid)

//9 Max/Static Compression Ratio

//10 Damping Ratio (0=Undamped, 1=Critically Damped)

//11 Extension Time (seconds)

//12 Retraction Time (seconds)

//13 Sound Type

 

point.0 = 1, 0.5762, 0, -3.8, 1500, 0, 0.522, 22, 0.25, 2.5, 0.65, 0, 0, 0, 140, 140

point.1 = 1, -4.9947, -4.5538, -3.4, 2500, 1, 0.6, 0, 0.3, 2.5, 0.7, 0, 0, 2, 140, 140

point.2 = 1, -4.9947, 4.5538, -3.4, 2500, 2, 0.6, 0, 0.3, 2.5, 0.7, 0, 0, 3, 140, 140

point.3 = 2, -4.6412, -17.9521, 2.8682, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 5, 0, 0

point.4 = 2, -4.6395, 18.1128, 2.9254, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 6, 0, 0

point.5 = 2, -20.1678, 0, 1.166, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0

point.6 = 2, 4.5586, 0, 0.2944, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 4, 0, 0

point.7 = 2, -20.4487, 0, 6.7034, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 7, 0, 0

point.8 = 2, -3.2653, 0, -1.7965, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 8, 0, 0

 

 

I take it point 1 and 2 are the left and right wheels but since they are both equal I'm not sure what to change.

Nope, not a contact point adjustment.

 

Animations are coded into the .mdl file.

 

Have you asked the nice folks at Carenado about this?

Carenado? set them an email from their support forum. I'm sure I'll get a response by Labour Day;);) Searched online but couldn't find anyone with the same issue.

As has already been pointed out, your issue isn't a contact point issue. However, no, points 1 and 2 are not the same.

 

Taking your cfg, I have color-coded the parts that answer your question:

 

[contact_points]

static_pitch = 3.82

static_cg_height = 3.22

max_number_of_points = 9

 

//0 Class

//1 Longitudinal Position (feet)

//2 Lateral Position (feet)

//3 Vertical Position (feet)

//4 Impact Damage Threshold (Feet Per Minute)

//5 Brake Map (0=None, 1=Left, 2=Right)

//6 Wheel Radius (feet)

//7 Steer Angle (degrees)

//8 Static Compression (feet) (0 if rigid)

//9 Max/Static Compression Ratio

//10 Damping Ratio (0=Undamped, 1=Critically Damped)

//11 Extension Time (seconds)

//12 Retraction Time (seconds)

//13 Sound Type

point.1 = 1, -4.9947, -4.5538, -3.4, 2500, 1, 0.6, 0, 0.3, 2.5, 0.7, 0, 0, 2, 140, 140

point.2 = 1, -4.9947, 4.5538, -3.4, 2500, 2, 0.6, 0, 0.3, 2.5, 0.7, 0, 0, 3, 140, 140

point.3 = 2, -4.6412, -17.9521, 2.8682, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 5, 0, 0

point.4 = 2, -4.6395, 18.1128, 2.9254, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 6, 0, 0

point.5 = 2, -20.1678, 0, 1.166, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0

point.6 = 2, 4.5586, 0, 0.2944, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 4, 0, 0

point.7 = 2, -20.4487, 0, 6.7034, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 7, 0, 0

point.8 = 2, -3.2653, 0, -1.7965, 1574.8, 0, 0, 0, 0, 0, 0, 0, 0, 8, 0, 0

 

The key numbers shown in the introductory comments (//0, //1 //2, etc.) are column numbers. Therefore, "//2 Lateral Position (feet)" means that the lateral offsets from datum (centerline, in the context of lateral offsets) in feet are in Column 2, which is the third column since the first is Column 0.

 

In this case, the fact that points 1 and 2 coincidentally happen to be the main landing gear legs and therefore have brakes makes it even easier to identify left and right since differential braking requires that left and right brakes have their own discretely-labeled contact points.

 

A lateral offset value of -4.5538 is the opposite of 4.5538, and negative lateral values mean left-side offsets.

 

Also, just as info, negative longitudinal values are aft of datum and negative vertical values are below datum... and vice versa in both cases. "Datum" is often the aircraft's empty Center of Gravity (CG) but it can actually be any point the aircraft modeler chooses, although I have never heard of a Datum that is not on the aircraft's lateral centerline. I have heard of modelers selecting the tip of the nose or prop spinner as "Datum," which means that point is at coordinates "0, 0, 0" and all other points on the airplane have negative longitudinal values because they are all aft of datum.

I realized the negative referred to the left and positive to the right side.

There is nothing wrong with contact points. I went over them with a fine tooth comb. The only other explanation is 'PARKING BRAKE'. If you have your parking brake on the wheel(s) will not rotate (annimation). The engine might be powerfull enough to 'drag' the gear, especially if the ac is a light plane. Check your parking brake. So if that is not the problem (which is just a stab in the dark) then it HAS to be the MODEL.

This plane has been out for years and they just realized this now? LOL

 

response from Carenado.

 

Carenado Support, Apr 30, 10:14:

Greetings,

 

You are absolutely right, sorry about that. We are writing down all of these details for every aircraft to fix them as soon as we can.

 

Regards,
