HITL setup crashes with custom airframe

Hello everyone,

I have built a custom multicopter airframe which is working perfectly with SITL however when i enable HITL for the same airframe and the same gazebo world the multicopter crashes as soon as i take off.

Im using a custom 1.13dev PX4 firmware with QGC and running HITL with gazebo

Any advice on what should i look for?

What exactly crashes? Can you give more information what you see?
