Low airspeed with fixedwing

Hi guys,

I made 2 test flights with a modified version of v1.7.2. For some reason airspeed was very low, around 11m/s instead of 16m/s. Thrust SP was low as well. Below are 2 logs made on the same day. Any help on finding the source of the problem is much appreciated.

Thanks

I figured it out. FW_THR_SLEW_MAX was cousing the problem.
