Standing just over 20 inches tall, this mini engine powered rocket packs some punch when launched on an A10-3T. The Sequoia is quick off the launch pad and soars to 350 feet so you better keep your eyes open when it takes off.

WHAT YOU NEED TO BUILD: Scissors, pencil, ruler, fine sandpaper, carpenter’s glue, hobby knife, clear tape, primer (white) and paint (black, blue, white). (Tools, construction and finishing supplies not included.)

WHAT YOU NEED TO LAUNCH (sold separately): Estes Porta-Pad II Launch Pad with a 1/8 inch launch rod and Electron Beam Launch Controller, Estes model rocket engines, starters and recovery wadding. Four 1.5V high quality AA alkaline batteries are also required for launch controller (not included).

Build History

  • 11/07/2019 – Took pictures of package.
  • 2/15/2020 – Opened package. Took pictures and scanned contents of package. Cut tube marking guide and shock cord mount from a copy of page 2. Removed balsa parts from sheet and sanded them smooth. Rounded the leading and end of the fins. Marked motor tube at 1/2″ and 1-1/4″ from aft end. Cut a 1/8″ slit at the 1-1/4″ mark. Placed engine hook into the slot and glued the engine block into the forward end so it was even with the end of the tube. Glued the engine r hook retainer ring at the 1/2″ mark. Cut a 1/8″ gap in one centering ring and glued it against the bottom of the ring. Glued other centering ring even with the forward edge of the motor tube. Marked the main body tube with the tube guide and extended the lines the length of the body tube. Glued the fins on the guide lines and glued the launch lugs onto the standoff pieces. Glued the launch lug and standoffs 1/2″ from each end of the body tube along the launch lug guide line. Filleted all joints with yellow glue. Glued nose cone and balsa body tube transition to the large body tube. Glued screw eye to bottom of transition piece. Glued shock cord to mount and then 2″ inside of small body tube forward end. Tied other end of shock cord to eye screw. This completes construction of Estes Sequoia #7233 except for paint and decals.
