Hi there! Anyone managed to fly the Strugatsky really high? I'm doing test flights, but the prograde keeps dropping from 14km and above. At 18km it is at about 25° lower from pitch and you can't really pitch higher than 25°, because the drag flips you over. Above 18km the prograde drops below zero and start losing height. PS. I've put another pair of engines and a couple of radial intakes on each engine. Intake is not a problem.
