And how would they compare with paper Tubes in strength and mass.

i know I’d need to put some parchment paper or some other protector along the first say 6 inches forward of motor to prevent melting, and I know the tubes wouldn’t stay clear, they would soot up in a hurry. Thing is, I’d like to get one or two just to make curved fins for Horizontal Spin Recovery, but they come in lots of 50 For $40 plus shipping. That’s a bit pricy for just one or two, and unless I could use them as body tubes I have 48 useless plastic tubes that I don’t need and didn’t want to pay that much. OTOH, BT-50 outside diameter is
These are
Difference 0.144 inches , about 3.6 mm.
with a bit of tape would fit a BT-50 nose cone.
would probably need to do thru the wall fins, as hard to get stuff to stick to this.
a plus is the absence of spirals, and @Dotini says they get brittle with paint.
