      Thanks Charlie. I have become well aware of the "IVO" prop problems

   and limitations thanks to my friends on the group. I am hopeing to help

   the efficiency of the "IVO" by covering most of the flat hub area with

   the 16 inch (Mustang Two) spinner. After getting airborne I may try

   cuffs next the spinner (like Tracy). As a point of interest what engine(s)

   did you attach your "IVO" to ? For the groups info Jim Maher is very

   close to flying his "Dyke Delta" (13B/Ross 2.85/EC2/IVO -3 blade).
