Hi George,

The Rotary Engine Press paper I sent you mentioned the Renesis rotors are
lighter and illustration should less material in the inner metal walls.
However it might amount to only a few grams.  Can anyone out there weigh one
for us to confirm it?

Doug in Japan

I can't tell you how many grams but it was about only an ounce or two.
Something less than a 1/4 of a pound. A regular rotor is about 9 pounds.
