What about an Alliance U110 rotor (rated at 5 sq ft load) $200 and just a 1 3/8" mast for the setup..


3 element Maco or Sirio and the A99..


Right around 5 sq ft total..


Then I could use a different 'rocket top' that fits the smaller mast better using the TB50 bushing..


I really don't see me going larger up top..


The A99 would then bolt right on the 1 1/4 - 1 3/8" mast without issue..
