Hi ,
According to the http://www.fifth-r.com/cssoh1/actest.htm, a
mini-compressor (using a single small pump) is actually more efficient than
using double pump. It said more efficient, but not generate higher output
though, correct???
http://www.fifth-r.com/cssoh1/compress/compdisc.htm produces a more
persuasive test. However, it is not motorized. I wondered if there is
anyone who has done a comparison the acculumative power output in a more
extended period of time, say merely 30 seconds or so...

Yes, I also want pneumatic steering.

I don't quite understand this... But again, I am a newbie, I should read on
the pneumatic info first before I ask too many questions.
