The Model Rocketry Handbook: 21st Century Edition

G. Harry Stine, a pioneer of model rocketry, wrote "The Handbook of Model Rocketry" many years ago but it is still relevant. I added links for two book options. These sites are U.S. links. Not sure if they will work for you. https://www.amazon.com/Handbook-Model-Rocketry-7th-Official/dp/0471472425/ref=mp_s_a_1_1?adgrpid=1334807687301940&dib=eyJ2IjoiMSJ9.GkK94XZAqbmwCrzrK4zEavd2BwvzuJXtKxFtjtrB8RQrefRVwcE7XF3_43lqUwd5ta7sacfH7Mp17WIFvagl_YmZsuJjZSLfVxA4H4YRmzL_Q_b8bvw1sB_c9jiOiGt43N-VVfsPVRAkvzTa_q6b8xV8Wm9ZPojtXqXQ6rsrwLs78T6q5Mb00ZpoEJoonNOyLkw6763ZF2UeL_ubIg9Agw.asj7Cf3Jf0r9O4KUvrUhz0mNb7qa6siU-HfgcydjEOo&dib_tag=se&hvadid=83425719868547&hvbmt=bp&hvdev=m&hvlocphy=77876&hvnetw=o&hvqmt=p&hvtargid=kwd-83425839711531%3Aloc-190&hydadcr=22627_13496669&keywords=handbook+of+model+rocketry&mcid=cfe1c75ff954390fa8cb38579b2a4ccb&msclkid=882c25d65ffe1c5e3fad4c684bd4b592&qid=1774064688&sr=8-1 https://www.amazon.com/Model-Rocketry-Handbook-21st-Century/dp/1854862294/ref=mp_s_a_1_3?adgrpid=1334807687301940&dib=eyJ2IjoiMSJ9.GkK94XZAqbmwCrzrK4zEavd2BwvzuJXtKxFtjtrB8RQrefRVwcE7XF3_43lqUwd5ta7sacfH7Mp17WIFvagl_YmZsuJjZSLfVxA4H4YRmzL_Q_b8bvw1sB_c9jiOiGt43N-VVfsPVRAkvzTa_q6b8xV8Wm9ZPojtXqXQ6rsrwLs78T6q5Mb00ZpoEJoonNOyLkw6763ZF2UeL_ubIg9Agw.asj7Cf3Jf0r9O4KUvrUhz0mNb7qa6siU-HfgcydjEOo&dib_tag=se&hvadid=83425719868547&hvbmt=bp&hvdev=m&hvlocphy=77876&hvnetw=o&hvqmt=p&hvtargid=kwd-83425839711531%3Aloc-190&hydadcr=22627_13496669&keywords=handbook+of+model+rocketry&mcid=cfe1c75ff954390fa8cb38579b2a4ccb&msclkid=882c25d65ffe1c5e3fad4c684bd4b592&qid=1774064811&sr=8-3
