The IPD esc is not the best in my opinion. The brakes are not good at all. I would recommend a Quantum esc. They are small, light and work with the 1/10 scale cars. Not to mention that the brakes are quite good.
I did the rage system on the latest vendetta mini. It's wild and everything fits, I did a full write up for everyone to see. Check the picture out on the www.mimxra.com message board under the mod section. with the stock gearing I bet 80mph is not out of the question. I should have video soon for this on the site.
