update on my "rolling" issue. Upon checking... 1 gold spring has lost tension. I can move the shoes back and forth 2 to 3 mm. I changed the "suspected" spring. Use the same shoes and also Losi Steel Flywheel and the issue is gone. Car/Engine was insane and i was driving "carefully". Joined local race sunday and was able to move to 1/4 finals, but drivetrain issue (actually my fault also, did not check).

thanks for all the help...
