Polecat 5.5 Pershing 2

[stmoon]

Greetings
In course of moving parts for the pershing got separated and the 38 mm motor tube is gone. So does any one who built one give the specs for it.
Thanks

Use a LOC 38mm MMT. I think it's 8" or 12" between the two centering rings? But it's not critical, you could use a longer length if you want. What is the length of the root edge of the fin's tab? That's where the rings go.

Does any one have rocksim or open rocket on the Polecat Pershing 2?
Trying to insure cp/cg is okay for flight for Airfest this weekend.
