i havent tested it with both of em locked cause the metal bonding material needs 24 hours to fully bond the metal, but i have driven it with the rear locked...it handles great doesnt flip at top speed although i havent set my ESC up yet so i dont know if its really going full speed. but jsut with the rear locked it offroads very well but also it drives great on the pavement too. im very excited to test it tomorrow with both locked...im sure it will be beyond great.
