VTOL won't take off

Hello all, I hope you are well. We have built a VTOL and after successful calibrations, when it came to doing a test flight, motors spun but didn’t generate enough lift the drone. We can’t seem to understand why the drone won’t take off. Can you please help us understand what might have been the issue?

Hello Eric, you are going to find better response under arduplane topics, vtol code is arduplane not arducopter.
Does your motors props have enought power to lift your vtol weight, batts are fresh and well charged?,
