That should fly nicely on the 29mm Estes F15's.
I would not fly that thin-wall tubing thing on a motor with any more kick than a Aerotech RMS24 F24 though.
Certainly NOT on a REAL F or G like the F52 or G80.
The tubing will probably crumple.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
