I’ve weighed all the components of the rocket. I’ve tabulated them below.<\/p>\n

To identify which parts I’m referring to, I’ve included a picture of the components on the installation instructions.<\/p>\n

\"front-page-components\"<\/a><\/p>\n

 <\/p>\n

Booster Airframe:<\/strong> 1494 grams<\/p>\n

Motor Mount:<\/strong> 443 grams<\/p>\n

Payload Airframe:<\/strong> 721 grams<\/p>\n

Nose Cone:<\/strong> 349 grams<\/p>\n

Nose Cone Coupler Tube:<\/strong> 222 grams<\/p>\n

One Top Fin:<\/strong> 151 grams<\/p>\n

One Bottom Fin:<\/strong> 113 grams<\/p>\n

Bridle Strap:<\/strong> ~40 grams<\/p>\n

Avionics Bay Fibre-Glass (52mm length):<\/strong> 60 grams<\/p>\n

Avionics Bay (Wood + Bulkheads + threaded rod + nuts + washers + eye-ring bolts<\/strong> : 395 grams<\/p>\n

Nose Cone Bulk plate + Eye Bolt + Nut<\/strong>: 90 grams<\/p>\n

Avionics Bay Coupler (275 mm)<\/strong>: 322 grams<\/p>\n

Centering Rings (2 of these):<\/strong> 15 grams<\/p>\n

We need to know these weights so that we can create a simulation file in Openrocket to simulate the flight of the rocket.<\/p>\n

 <\/p>\n

NOTE<\/strong>: I’ve opted to use a different sled arrangement in the Avionics Payload. Wasn’t happy with the one provided. The weights are almost the same, just a few grams lighter.<\/p>\n","protected":false},"excerpt":{"rendered":"
