737 Flight model unstable

ISSUE DESCRIPTION

Description of the issue: The 737 max 8 flight model is very unstable.
If you pitch up or down, it will bounce up and down a lot before stabilizing a few seconds later, but often in an unpredictable location.
This happens with both elevators and trim.
The only solution to avoid this is to use trim to fly the aircraft vertically, though this also suffers from the same exact issue and at some point you will need to apply horizontal input for ailerons, at which point even the slightest up or down motion will trigger the bouncing again.

If applicable, which aircraft is experiencing this issue:
Asobo 737 Max 8

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
Yes.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every flight

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Spawn in at airport on the rwy with the 737
  2. Take off
  3. Observe how pitching up or down, even with departure, leads to a highly unstable motion of pitching up and down.
  4. Use trim to control the elevators, observe how it’s a little easier but still leads to difficulty

Confirmed. What I’ve noticed is I cannot trim the aircraft properly and I fight with the pitch to stabilize on postion. It goes either too much up or too much down.

I cannot agree more with that part during the landing. When the plane comes closer to the ground and should start to flare, it pitches nose so strongly up, that it is almost impossible to land it nicely.

Ill vote for this. Its very uncontrollable in pitch. In addition to its bleed air and electrical transfer issues.
