LOC Iris PK-25 Modification

[Valkyrie]

I have the kit assembled but it looks too short. I am planning on extending the body tube 12" with a coupler and extra section of BT. Possibly extending the NC instead and making an AV bay.

Any thoughts?

So I can't figure out which kit is the PK-25. My Park Flier IRIS (the 1.63" kit) is at my other home(my house. At the GF's tonight, don't ask, it's complicated...), but I do remember that it has a second tube at least 8" long. If you can wait a day, I'll measure it tomorrow.

its the 2.1" sized rocket. 39" oal. Just looks and feels a tad stubby.

Oh, OK, different rocket then.

To scale the sustainer of the Iris sounding rocket is almost exactly 20:1 (238.1”:12.0"). Is your rocket 32.5" long?
