Did someone say RockSim? I have attached detailed RockSim files for both designs. Note these simulations contain pods and cannot be used in Open Rocket software. Files suitable for Open Rocket software can be found in the RockSim Asylum at: https://forums.rocketshoppe.com/sho...451&postcount=1

Note: There was an error in the transition section of my original post; a new RockSim file where the transition is now marked as hollow instead of filled polystyrene is included for the 1320.

The 1340/20 RockSim file is definitely better than mine! Thank you for posting.

Do you have a link to the one with no lug ? I like this option.

Thanks

Motor mount tube and centering rings...

Make a mark around one end of the MMT that is half an inch from the end.

This 29mm motor mount tube is cut to five inches in length. Two half inch lengths of the same 29mm source is cut and split width-wise only once. Then slide onto them onto the motor mount tube and glued in place. You may have to sand a little to make sure it fits into the airframe tube.

Drill a hole in the smaller end of the reducer/transition and glue in a screw eye.
