Yes the CoL is ALWAYS behind the CoM but I suck at re entering
#How do I re enter an atmosphere in my ssto without violently spinning out of control

the only way is to hold prograde but then u will burn so u will spin everytime
U will get control back when u at low speed again

So everyone spins?

No. Your com is shifting in front of CoL or you don't have enough control surfaces. It can take a lot of testing at this design phase so i try to keep multiple saves of my plane in case i make a change and ruin it

don't you need really big wings to hold radial to break down?
I brake by spinning around😅

spinning isnt usually a good idea, you can burn off expensive stuff
not likely but you can

to spin to not burn anything

you usually want to emulate real life spaceplanes which pitch up to 40 degrees on entry

my ssto just flips back when I turn it up
thats the problem and reason why I spin it around
tight pewter
the best way to do this is to have absolute control authority and a stable center of mass and lift. I find the best way to find this while testing is to use a mod like mechjeb to see the center of mass and lift in flight
that means you do not have control

oh ok
tight pewter
radial out means point straight up, radial in means point straight down
so no idea what youre trying to do

my last ssto spinned retrograde how I can get it back to the right direction?
tight pewter
well not pointing straight up is a good start because that will flip you
warm dome
but that not really matter in my case bis its just full length up or down
warm dome
well not pointing straight up is a good start because that will flip you
yes but I didn't knew how to break down otherwise
tight pewter
now you do :)
warm dome
my first small ssto didn't flipped and when it turned back prograde
warm dome
now you do :)
yes thx
but one question😅:
when my ssto is turning retrograde is my center of mass to much in the back or front?
tight pewter
in front
wait no sorry
so when it isnt pointing straight that means center of mass is behind center of lift
warm dome
ups ok
Ill try to put all remained fuel forwards then
but I have not much
well im already landed but it was more a crash so I gonna try it again

When descending, don't follow prograde but hold the nose some way above prograde to generate drag and lift rather than spearing straight ahead. An aircraft doing backflips is a sign your centre of mass has shifted in-flight behind your centre of lift. Before you fly, take the fuel out of the tanks to see how the CoM moves as the fuel drains, and in flight the CoM is the camera focus point so you can mark the CoL in the SPH with a small object to see how CoM moves relative to it in flight.

ye my big ssto was not good balanced
