Welcome aboard, 

As there is a CoM indicator,  also there is a CoT (center of thrust) indicator. Adjust your staging/thrust limits so only the vertical engines contribute to de CoT and check if it line up with the CoM

Another important think to consider (vtol or not)  is how the CoM shift as you burn fuel.  Wouldn't be nice to design a vtol that spins uncontrollable with a few units of fuel burned.

I would recommend using RCS Build Aid, which tells you where your center of mass will be when your fuel tanks are empty, as well as the exact amount of torque your engines produce - two vital pieces of info for VTOL design you can't easily find in stock. At least not as easily as with this mod. You could eyeball it, but that'll take significantly longer to design.
