Enerjet 1340/20
 

Attached are RockSim flight simulation files for the Enerjet 1340/20. These files do not contain pods so they can be opened with Open Rocket software. More detailed RockSim simulation files that contain pods can be found at: https://forums.rocketshoppe.com/sho...49&postcount=11

I also attached screen shots from both simulation files.

Thanks, Bruce.

2-micron polish on the finish? Really?

The mass of the transition was way off - you specified "filled" polystyrene. I fixed that. Even so, they are way too heavy. I weighed one of the "Eggspress" egg capsules that Estes sold off long ago. I'd override the mass of the nose cone/transition combo to around 28.68 grams. Split the difference between the nose cone and the transition 25/75%, or 7.2/21.5 grams.

Your total mass for all the components of the fin can is very close to the mass of a Maniac fin can that I just measured - a few grams more. Close enough.

I decided to build one of these too, but not the 10-inch long payload bay version.

Wolf,

Thanks! I fixed he error on the transition for the 1320 in my post.
