Tricopter consuming more power than required to hover

ArduPlane VTOL Plane

Hello,

I built a Tricopter VTOL UAV with AUW 10.5Kg. Each motor at 50% can give approximately 4.5kg of thrust consuming 20A. But when the drone hovers it takes in 90A and a voltage drop of 2V. The power module is calibrated and the plane is tuned. Not able to figure out why the excess power consumption. Any suggestions.

What motors and props? 6S power right? Based on the Rcout’s at hover the thrust/weight doesn’t look bad for a VTOL.

Front two motors are T motor AT5220 380KV with 19x10 props and back motor is T motor MN605S 320KV with 22x6 props. It is a 6S system. Firmware is the latest stable version. Could vectored yaw be the reason?

Thanks
