Fine tuning AIR file and aircraft.cfg (need help)

Hello fellow aicraft design experts,I

If your aircraft is going over on its nose when you brake, then you probably need to reduce the braking strength in the airfile.If you don't have this utility already, then go to this site and download AirEd:http://perso.wanadoo.fr/hsors/FS_Soft/fsairfile.htmlWhen you open the airfile with AirEd, look for Rec 1101 Primary Aerodynamics, click on the + sign to expand this section, and find the entry "Braking Strength-Max ft/sec^2*2048)=32767".The default value here is usually 32767. You want to reduce this number, and since the AMT-200S is a lightweight taildragger, I would reduce it to 22000 to start, and then begin testing. From the information on the Ximango website, you're looking for a maximum ground roll of 140m/460ft.If you find a negative number for braking strength entered in the airfile, then take a look at reply #5 in this forum thread: http://forums.avsim.com/dcboard.php?az=sho...ing_type=search

One of the first things to look at is the brake effectiveness.Download the free "Aircraft Airfile Manager V1.0 beta 6 / January 12th 2003" from _http://www.aircraftmanager.com/ and find the brake record. Adjust the values and see if that prevents the nose over.You may want to watch via replay and see what he gear is doing. Is it diving into the runway? Is the nose gear too soft?This link here shows how you can change the effectiveness of the brakes with AAM. _http://mtco.com/~rsam/brakes.gif
