Ineffective braking FR's Me 109K-4

Hello everyone.
Had a HD crash back in June (no biggie) something to do with a corrupt .dll. Anyway was able to save all my aircraft for FS9, but for one, my Me 109K-4 from Flight Replica. Luckily I have it on disc. But the one thing I do not have is Mike Cyul's fix for the creeping of the aircraft at idle and on landing, the completely ineffective brakes. You literally cannot stop the aircraft. I know Mike had/has a simple fix that he posted at the SOH, but for the life of me I cannot remember what it was. Can anyone help. If you have the fix you can PM me or contact me at wdgibby@ibl.bm

Many thanks

Derek
 
It doesn't work on everything but I believe under the aircraft cfg section [propeller], the value at --> minimum_on_ground_beta = 1.000 <-- can be reduced to stop the creeping. Another tactic is to reduce the static thrust elsewhere, but that can lead to a domino effect at the least.
 
Thanks aeromed202
I went to all this trouble and I forgot that just before the HD crash I had backed up my entire aircraft/FS9 folder to an external HD. Just copied over the models (3) file for the K-4s and they had the update in them. That took care of the high power brake creep and ineffective brakes. Once I add in the aircraft I want this time I will make a new backup.

Thanks

It is typical for most WWII high powered aircraft to be able to skid the brakes with greater throttle settings. The brake scalar in the Cfg. file controls the effectivness of the brakes. Also there should be a parking brake line. However if the plane is creeping at idle, probably the idle is set too high, giving too much thrust . Generally this is controlled by the min MP and by the 509 table in the air file which controlls internal fricton vrs RPM. Many FS planes idle too high, at 1000 plus RPM, 650 to 850 is a good minimum idle speed. Also the prop min governing speed should be somewhere around 1400 RPM.. I do not have the plane, so cannot specifically comment on which of these migh effect your issue. Generally this is a bigger problem in FSX as the coefficent of friction with the ground is higher.

Hello flieger747
Your wrong there. The parking brake does exist. Did I side by side aircraft.cfg comparison and they were identical. Also compared with the 109G's cfgs and outside of some engine power and weight setting, again, everything was identical. Anyway the problem is solved. My next big issue is to get FSX working properly. Just cannot get it to function right.
[brakes]
toe_brakes_scale=0.50355
differential_braking_scale=1.0
parking_brake=1

The problem was with the model mdl.file itself. Mike corrected that and upgraded his original zip package (v1.1) and that solved the braking problem. I unfortunately only saved my original disc/zip and the update was sent to me via email. Ehh. Lost the email after I had done the update. Luckily I had the FS9 aircraft file (all my aircraft) backed up to an external HD. So I just copied the mdl.cfgs over and hey ho away I go.
 
To reitterate, I do not have the aircraft, so the intent was to check that there was a parking brake entry.... (in the spirit of tech support asking if it is plugged in) For FS9 that is possibly a somewhat smallish brake scalar, though the real BF109 series probably had crummy brakes.

For troubleshooting such issues I reccomend the AFSD utility by Herve Sors, easy enough to check how much idle thrust is being delivered, idle RPM, prop pitch etc. Hard to imagine anythng in the mdl file affecting this.

Good Luck! T
