The technical theory FM arguments are way over my head but I appreciate everyones input. I just read Cambers post (excellent too!) and it refers to the Acusim modelling of the Spit.

I asked someone who has this installed how the Spit compared to the one in CloD regards handling? His opinion was that it was very similar (better in some aspects regards performance).

I appreciate that it has little significance in contributing to this discussion but I would be interested to know if there is a marked difference between the FM modelling given to us by MG and another such as Acusim both of whom I would imagine are researching and using the same data.
