Hi Everyone,

This is my forst posting so please bare with me if I get something wrong.
This is just a simple question regarding the 20b and aluminum housings
available from www.racingbeat.com.

1 - Will these "fit" the 20b engine?
2 - Do these require machining or are they ready to be used as purchased?
3 - The baseline for my aircraft is the Lycoming IO-360-A1A which I believe
is certified at 328 LBs.  Does it make "sense" to spend the several
thousands of dollars to shave about 50+ LBs off of the 20b (assuming these
housings can be used)?  Any arguements against using these items reliability
wise?

The aircraft is an Osprey GP-4.

Thanks a bunch.  Can't wait to see the replys.

1. Three out of the four housings can be replaced by RB aluminum housings.
2. no machining is required.
3. I would use a 250 HP RX8 p-port 2 rotor cast iron engine rather than a 3 rotor
  20B. The firewall forward weight would be about the same as an IO-360.
