Both my truggies have solid center diffs (Which acts like a direct drive, motor in the center going straight to the F/R diffs) and they act just like a 10th scale 4WD vehicle. My MBX5T turns on a dime and the tank BPP does turn on a dime when traction is available .
You have to many posts to go back and find pictures..
Could you post or send me pics of trucks with direct drives?
