#5 11k25 Energia-Buran almost fails

[Stäphen Goedzal]

11k25 Energia-Buran test craft guided by energialaunch.ks yaws sideways suddenly at BlockTs cutoff, causing a "control error".
May be a long standing problem caused by always launching from the equator previously?

Occurs since KSP 1.10.

It's related to what americans call "dutch roll". i.e. when a massive object gets a small yaw, it's nearly impossible to correct due to inertia... especially near space where aerodynamic forces don't do anything.

I've set the top RD0120s to only cut to about 25% instead of off. which seems to fix it The only information I have about what the Energia really did is from
https://www.amazon.com/Energiya-Buran-Soviet-Shuttle-Springer-Praxis/dp/0387698485
which just says "the outer RD0120 engines shut off", or something like that.

Closing for now.
