Talking of higher power higher load conversions
A guy in Sydney has done a conversion on his ute (pick up in American speak)
using a 3 phase motor and controller he bought second hand
not bad considering he lives in the most hilly part of Sydney
as featured in siliconchip
magazine<http://2.bp.
his blog <http://a4x4kiwi.
I found his blog a bit messy
you have to dig through the months to follow the conversion
unless Im not navagating it correctly
