ShrikeHawk Posted May 15, 2011 Posted May 15, 2011 (edited) I've been working With Wolf's Bf-109F and struggling with one odd problem. It skitters / veers to the side at low speed during landing and take-off. This is flying manually, by the way. I've poured over the data.ini file looking for unequal values. It's been driving me crazy! And then, just now, I saw this... It seems this is the problem. One leg is too long. Anyway to fix this? Edited May 15, 2011 by ShrikeHawk Quote
Teras Posted May 15, 2011 Posted May 15, 2011 (edited) i had this problem before http://combatace.com...e-by-migbuster/ check it out , the cure is there under number 17. good luck mate Edited May 15, 2011 by Profi Quote
Wrench Posted May 16, 2011 Posted May 16, 2011 have you adjusted the rolling radius and the shock spring and damping?? (btw, this is a MAJOR issue on just about all 1stGens built prior to 06, and many built later) wrench kevin stein Quote
+russouk2004 Posted May 16, 2011 Posted May 16, 2011 as wrench says...look at the main gear entries for left and right u\c and check the numbers match up...in bothas below... [LeftMainGear] SystemType=LANDING_GEAR Retractable=TRUE DeployTime=5.0 AnimationID=2 DragArea=0.50 HideGearNode=FALSE ModelNodeName=MainGearStrut_L InsideNodeName=LeftGearWell ShockAnimationID=-1 ShockStroke=0.15 <<< check this same other gear SpringFactor=6.0 <<< check this same other gear DampingFactor=2.0 <<< check this same other gear WheelNodeName=MainTyre_L RollingRadius=0.449 CastoringWheel=FALSE HasBrakes=TRUE BrakingCoefficient=0.75 RollingCoefficient=0.05 MaxDeploySpeed=128.61 MaxLoadFactor=6.0 Quote
ShrikeHawk Posted May 16, 2011 Author Posted May 16, 2011 Thanks fellas. This is helping. Both sides were (originally) exactly the same. I have to set them unevenly to get the plane balanced. Very strange, but oh well. Now it's a matter of fine-tuning. Quote
Wrench Posted May 16, 2011 Posted May 16, 2011 that means the mirrored faces of the meshes are not perfectly aligned ... you'll find many occurances of this on older models. 06 level games (and eariler) were a bit more forgiving, methinks wrench kevin stein Quote
+Dels Posted May 16, 2011 Posted May 16, 2011 It could also be the shock orientation. Does the strut compress in the correct direction (i.e. up) on the right hand side? Quote
ShrikeHawk Posted May 17, 2011 Author Posted May 17, 2011 Finally got this as near to acceptable as I can. It's still a bit squirrelly, but the BF-109 was like that in real life. I thought had to set the values unevenly to make the plane rest evenly. That worked but take-of and landing were still uncontrolled. Eventually, I found settings that could be equal on both sides and also correct the extra long right landing gear. Here are the old and new settings. ORIGINAL [LeftMainGear] ShockStroke=0.20 SpringFactor=2.0 DampingFactor=2.0 RollingRadius=0.292 [RightMainGear] ShockStroke=0.20 SpringFactor=2.0 DampingFactor=2.0 RollingRadius=0.292 Even though the values are equal, this produced a right gear that was too long and uncontrolled handling on the ground above 40Kts. So I looked up Migbuster's guide to correct the right gear. No matter how much I adjusted the rolling radius it wouldn't move the wheel "out of" the tarmac until I adjusted the shock stroke to a very low value. Incidentally, you shouldn't adjust shock value below 0.01. The plane and the AIs will just flip over and blow up. Eventually, adjusting the shock stroke to the same low value AND the rolling radius to the same lower value got the result I wanted with balanced values. Here's the new settings. MODDED [LeftMainGear] ShockStroke=0.02 SpringFactor=2.0 DampingFactor=1.0 RollingRadius=0.279 [RightMainGear] ShockStroke=0.02 SpringFactor=2.0 DampingFactor=1.0 RollingRadius=0.279 This is still not perfect. Spring factor adjustments help, but unequal ones cause spontaneous bouncing in one direction. So prefer to keep them at the original setting. The plane still veers a bit, but at least it's controllable with rudder adjustments. The AI are able to take off normally. Quote
