The Aluminum rotor housings w= ill save you 15 lbs each.
I'm not sure how much (in weight) the Aluminum= side housings will save you but they are available as well.

The 20B= Center Housing can be had (in aluminum) as well but it is a bit pricey at = $5K +.

All available through www.rotaryengine.com
