33% more voltage should also give you 33% more current, so power (i.e.
voltage times current) should increase by 77%. But higher currents give
higher temperatures, which could damage the motor and would probably make it
less work less efficiently.
http://www.teamdelta.com/roboglad/ says that most of the robots ran the
motors at 18v, and the only problem was a molten battery box due to removing
the "thermally resettable solid-state fuse", so it *should* be alright but I
wouldn't want to try it myself :-)

| Yes, but they used more prats then the RIS contains :/ They used two battery boxes to gain 18V using this coupling: (URL) had a motorcontrolled polarity switch to walk around the voltage limits in the RCX. /Tobbe (...) (24 years ago, 7-Apr-01, to lugnet.robotics)
