Hello, I was wondering if there is any possibility of a large 2 1/2 stage sucrose and potassium nitrate PVC or Aluminum Casing reaching the Karman line or anywhere near it. Using an arduino guidance system. How large would it have to be and is it practically possible if not what needs to change, hybrid fuel, black powder fuel. Amature rockets have been to to space before what is the feasibility of this reaching space? Thank you for any help given!
