Cool Stuff!!! You probably know this already but, I'll mention it anyway for those who may not know and can benefit from my mishap.
With clear payload tubing coupled onto a balsa or other wood plug-coupler, if you decide at some point to fill the balsa with CA, either do so prior to gluing the balsa-plug and clear tubing together, or if CA is applied to the "inside" side of the balsa coupler after the balsa-plug and clear tubing are glued together, definitely mask the Inside of the tubing with paper rolled up and let it unroll itself to the inner wall of the tubing.
What happens is the CA fumes out soooo much, it will attach it's "fog" to the inside of what "was" a nice clear payload section. I know this from making that mistake for a payload section made for one of my night launchers (using clear payload sections and balsa plug couplers with LED's inside). From a night-launching perspective, enough light still shines through just fine, it's just aesthetically annoying.
Cool Rocket you have going!
