| - 2 - I feel sure you will find that the average 20 horse is K2/AB = to about .65 to .75, whereas the Phantom particularly 150" wheelbase is K2/AB = to about .45 to .5 and I believe if you establish these of figures definitely, it would be/very great assistance in the future design of the Phantom. Yours very truly, Maurice Olley MO/R | ||
