Rhombeus

Altitude 46,000m to 49,000m Speed 200m/s to 260m/s This is a very tough nut to crack. All my large craft seem to just fly off at angles from launch, even totally symetrical rockets with fins. The only way I managed to get up at that altitude was with a load of stacked hammers but I had no way of slowing my ascent so my speed was way to high. Anyone got any build ideas?
