I have faced a problem many times while building a plane. At 30000 feet when I try to pitch down the plane starts shaking uncontrollably. Do you know the exact reason behind it?

@DarthAbhinav yeah I know...
@DarthAbhinav it was, in the middle age or in the industrial age, maybe... but now it's Bangladesh...
@DarthAbhinav yes and I am from West Bengal
@DarthAbhinav both, I am a Bengali of Bangladesh...
@DarthAbhinav bengali is the main language of both of us
@DarthAbhinav he is Bangladeshi and speaks bengali with me
@MAHADI sothik karon ta janina
@AviownCorp eta mone hoy batasher ak prokar chaper karone hoy...
@MAHADI amar delta wings hole beshi hoy
eita amaro hoy, muloto pakha chikon hole eta beshi hoy...
@F104Deathtrap the problem occurs when I try it with delta wings
@ChaosEngineer always fast
@AviownCorp "the incident happens with the delta wings maximum time"
???
Is this Happening at when you are flying Slow or fast ?
@F104Deathtrap observed my old planes with delta wings, they worked fine without any ventral fin
@AviownCorp Please let me know what happens.
@F104Deathtrap ok I will try
@randomusername ok got it
@AviownCorp Yup. Most supersonic fighters have them for this exact reason.
@F104Deathtrap you mean ventral fin?
@randomusername what is z axis?
@AviownCorp This might not help, but try putting another stab as far back as you can on the belly. Obviously it won't be as big as the one on top because of ground clearance, the belly fin on a MIG-21 is a good example to work from. It was a delta wing design that suffered the same problem, the belly fin didn't solve it entirely, but it helped a great deal.
@randomusername it is still a mystery to me
@randomusername no those wings were of normal size
@F104Deathtrap I place the vertical stabilizer behind the wing at the top of the fuselage
