Finding the inertia matrix of a model

Hello all,

I’m trying to create a gazebo model of a vtol with two motors, for this I started from the standard vtol model that I turned and removed two motors. I put you my final results below. image description My goal is to make a model much lighter than the standard vtol (1,5 kg instead of 5kg). But this changes the inertia matrix and as I want to use my model with PX4 this one is very important. I tried to calculate it on meshlab but they tell me that my model is not watertight. Would someone have another solution to calculate the inertia matrix or has he already worked on this kind of drone and knows the coefficients? I thank you in advance for your help
