Thanks, If you are crazy enough to do twins, I usually hang out in the twins forum, then you really learn about reliability or ELSE!!!
With the VQ P-38, which also has ST 90's. (Note, not recommended by the manufacture of VQ at this engine size, but I NEEDED IT!!), I am flying two other twins with the ST 90's, one 108" P-38 with ST 2500's( One reversed), and one twin bash with ST 45's.
My personal favorite is the fox idle bar long.
Good Luck,
Twinman
