LOW QUALITY CONTROL ON THE MEASUREMENT OF THE GEARS CREATES OVERHEATED TO THE MOTOR AND ESC.

THE CONCLUSION IS, THE PRODUCTION  OF METAL DIFFERENTIAL GEARS MEASUREMENT IS SUCKS. NOT 100% ACCURATE, RESULT THE WHEELS TOO TIGHT, THE GEARS SPIN WITH FULL FORCES BY THE MOTORS THAT CAUSES OVERHEAT TILL TOASTED. ESC OVERHEAT AND TOASTED AS WELL. SOUND TOO LOUD.

NOT RECOMMENDED TO UPGRADE TO METAL GEARS. THE PLASTIC GEARS MORE SMOOTH AND FAST
