No. That thing has plagued the updated hvmaxx like... a plague. The little trans-orb chips keep going pop resulting in fire and exploded caps (seen numerous threads on the idiot forum about it happening). I would say you dont need an extra cap if you just run 3s lipo, but if you want to, a normal ~4000uf ( or 2x 2000uf) 25-35v low esr item is what you want, I think Mike and tekin sell suitable items in their shops
