Estes Mini Fat Boy Replica Model Rocket

thingiverse

Model rocket based on the 'estes mini fat boy rocket'. See below for build process: 1. Print all required parts (note 3x wings are required), can be printed without support. 2. superglue wings to lower body, they can be easily aligned to holes in body. 3. create parachute by cutting a 10" x 10" square from a plastic bag and use 2x 22" lengths of fine string (I used dental floss). Attach parachute to upper body as detailed on estes instructions - https://estesrockets.com/wp-content/uploads/Instructions/001499_RTF.pdf 4. cut elastic band to make 1 length (approx. 300mm is ideal) and connect to both lower and upper body. 5. fit wadding and parachute as per estes instructions above, note estes do sell wadding but I use toilet roll. Note you may require sellotape to ensure upper body fits to lower correctly (slightly snug bot not tight). 5. Fit estes motor and ignitor with plug (all parts purchased from estes), the rocket is designed to use estes C motors, I would recommend estes C6-5 motors. Refer to estes instructions above for fitment of ignitor. Note only complete this step prior to firing, do not complete in the house. 6. At this point the rocket is ready to fly. You will need a launch pad and launch controller, these can either be made but I would suggest just buying the parts from estes as they are not that expensive. Regarding the launch controller it can be quite fussy as to what battery will ignite the igniter, for reference I have had good success with duracell batteries. Note design has changed slightly when compared to the images provided, this is to improve motor retention.
