 Ken,

 I'm building a Glass Goose, which will accept a 13B with an in-line PRSU.
 However, the vertical distances are very tight.  A lower CG may be more
 appropriate and a higher thrust line might allow a larger prop -- which is
 currently a 65" Warp Drive.

 What size Warp Drive prop are you running?

 Do you have total weights on your PSRU's?

 Thanks,
 Scott Gettings

   I use a 70 inch 5 blade Warp drive.

   The weight on my 2.95 to 1 redrive is about 75 lbs.

   Ken
