  • tallest rocket 9.8 years ago

    Descent try but it only reaches 124,000'. If you want altitude, download my Atlas 302K. That'll get you a tad over 302,000'.

  • The ultimate rocket 9.8 years ago

    Ultimate rocket? It was inverted and out fuel before reaching 10,000 feet. Thanks for submitting but try a different design. Check my submissions for a rocket that will top 300,000 feet! Heston83

    The VAST majority of the weight is shed in the first 5 seconds. If anyone can build a higher reaching single engine, I'd be surprised.
