RCU Forums - Traxxas Stampede 2WD robot motor upgrade

Hi

I am a grad student doing a robotics project. I am developing an autonomous high-speed robot and using the Traxxas Stampede VXL (2WD) as my base platform.

I've added my electronics and extra sensors and have increased the weight quite a bit to ~5kg. In light of this, I changed to a 3S lipo and lowered the gear ratio to a 16/90 combination.

The problem is my speed has dropped to about ~16 mph. I would like to increase that if possible to about 20 -25 mph. Also, I am testing on grass.

Can anyone suggest a more powerful brushless motor which will work with my car? Will I need a new ESC as well? I would like something which is a drop in replacement with minimum modifications to the car.

Would this work:

Thanks in advance,
