Default CG / Landing gear relationship

Hi,

I would like to enquire whether there is any form of calculator that caters for the optimum landing gear position in relation with the aircraft's CG.
At the moment I am designing a Pilatus PC-21 and would like to properly locate the best location for its landing gear. As you may be aware the PC-21 landing gear is of the L type (as I call it) as the wheel shaft is rearward to the main strut. In my case, the wheel's shaft centre is about 2.5" (circa 63mm) behind the centre of the vertical main strut. Consequently, should the main strut be on the CG since the main wheel is rearward by the quoted amount?

Any assistance will be appreciated.

With thanks

Reuben
