I just centered the trim.
yes thats whats pretty much happening, however, the oscillation wont even out if i give it some throttle, the only reason it may seem like it is because its not regaining as much speed as in the beginning of the track.
It keeps pitching up and increasing AoA at really slow speeds, and with that gaining altitude until it stalls, then goes back down, and the process repeats it self, until it falls out of the sky.
if you look at the FBW pitch stability, (rctrl + enter) it doesn't vary the amount of push its giving the aircraft depending on speed, its linear and on the virtual joystick display (rctrl + enter ) it's always set at one spot, irregardless of the aircraft's speed.
