I will take it ALTHOUGH still a long time to become a veteran

3 stages LV

1-2 STAGES will take the 3rd one into elliptical parking orbit

Hp>1000km why choose Hp so high？？Ha=5500

MEO mission

overload of 2nd and 3rd stages seem to be too large reaching 7 and 11 respectively.

large overloads will require the structure strength design a heavy work.

velocity change between 1st and 2nd stage seems to be abnormal, as it drops down a little.

velocity of 2nd stage drops down for a long time because it is the process of moving from perigee to apogee.
