You need to study a bit more on R/C servo and H-Bridge theory and
operation.  Forget about NAND gates for now.  Before you start messing
with mosfets you need to become familiar with P and N channel devices,
high and low side drivers, charge pumps, pulse width modulation, etc.
(Google these terms).  As far as hacking servos and increasing their
power output check out these links.
