Hi all...
Recently, I've been practicing the inverted reentry using XR-5 and I love it.
Now I'm able to slow down without burning up when returning from Moon and Mars.
What I still can't do properly is turning back upright once I've slowed down enough and I'm not able to keep the Alt.
What I do:
Once ready to flip over, I disengage the AP and start banking manually for a 180dg flip.
I succeed maybe in 1 of 5-10 attempts as I don't have any given procedure to follow to perform the flip.
Vast number of attempts end up by 'HEAT DAMAGE' that occur during the flip.
Success is always matter of luck....which doesn't seem a good approach to space flights
Do you have any hints/procedure to follow in order to master the flip without damage?
Many thanks.....

What I do:
- just before reentry I set-up the Attitude AP to 180dg bank, 80dg AoA and engage it
- when the VS rises to around -150m/s, I quickly lower the AoA to 30dg to decrease VACC and once around 0, increase the AoA as needed
- keep adjusting AoA to descend, slow down and not to burn up
- from experience I know that once my SPD drops to M20, it's too late because I can't keep VS from rapid decrease anymore
- so around M22-23 it's time to turn back and continue in 'normal reentry'
Once ready to flip over, I disengage the AP and start banking manually for a 180dg flip.
