It cruises at about 135, yellow arc (tape) starts at about 140kts. As for soloing, it one of the owners personal aircraft. He bought it new but never flew it. When they brought it back here from denver to use it Only had 32 hrs on it. We can't solo in the arrow or Seminole either, but I think that is strictly due to insurance reasons.
I think the next thing that will top this when I get type rated on our t28 and my first time flying our c-123
