I found a fix for the drag brake issue.
found a 194 update, and installed that over my latest update.
set drag brake to 100 on hotwire. Drag brake actually locked up the wheels.
So I went to adjust the drag brake manually on the speedo to reduce it to the about 6-7 leds, and it was crap. Then adjusted on the speedo to the max led, and it was very bad also.
re-updated the RS with 194 again, adjust drag brake with hotwire, and...bingo, fantastic drag brake again.
So bottom line is, decent drag brake works only if you adjust the setting with the hotwire.
