at that attitude my rocket is almost horizontal. And my low twr (About 1.10) could not overcome the drag and the time to ap fall down until it reaches 0 and the rocket comes back down
dude i used 23 skipper engines for liftoff man!
skipper is currently my most powerful engine, five of them in the core stage
the payload is too freaking heavy
i chose to use the resilient 1b, the heaviest in my fleet.
