Default Bt70lite, use or get standard tube

some time back I bought some bt-70 airframe tubes from Apogee. I finally found a use for turns out that Apogee doesn't sell bt70 with the standard wall thickness of 0.021", what they sell has a thickness of approx. 0.017". I was thinking to build a 3x upscale of the Estes Hi-flyer for 24mm motors( Es and small Fs). now I'm wondering if I should buy a new tube instead of using the thin wall stuff I have on hand. my current design file attached. thoughts appreciated, thanks

Tubing sounds lousy.
I'd scrap it and use real stuff, especially with F power of any sort.
When in doubt, WHACK the GAS and NEVER touch the brake !!!
