Sirius Rocketry - For the Serious Rocketeer!

Estes Pro Series II So Long


  • Model: EST 9722
  • Manufactured by: Estes

There’s never been an Estes kit like this! Created for extreme attitudes, this high-flying two-stager can reach a record setting 3600 feet – that’s more than two-thirds of a mile! Includes a large payload section so you can send your high-altitude experiments aloft. And for safe returns, the two bright orange streamers are both easy to spot and designed to bring your rocket down quickly – don’t let this one drift away! A simple but rugged design means a fun build and you’ll be launching in no time.
