what type of material is used for the tube design?

I used a flourescent tube guard. https://www.lightingsupply.com/halco-tg ... FUEALw_wcB

Hey everyone,

I'm wondering how yall attach your fins. I use foam fins and tape them to the bottle and the attachment breaks every 1 or 2 launches (simply from the fins impacting the ground). Does anyone have suggestions on a more durable and rigid way to attach fins?

Any help is greatly appreciated!

i'd suggest working on getting your rocket to fly straighter then so that it doesn't land sideways. You could go the gorilla tape route with the fins but it would be beneficial for your release to straighten out the flight anyways

The rocket does go up super straight and mostly comes down straight so I have my parachute relase system all workes out. It's just that after the rocket falls down half way it starts to turn sideways, should I try to get rid of this tilt so late into the flight?

Thanks for your help!

If your release is fine it's probably not really worth messing with the bottle that much then. I guess stronger tape or just removing fins would work, I'm not actually sure fins do that much lol

I disagree. Fins are the best way to make sure that the bottle rocket actually flies upwards.

not sure if we mentioned this already but are there any ways to prevent flipping at the peak height? other than the tube design

idk in my experience nothing really changes with or without them

The tube design actually promotes flipping at peak height
You can shift the center of gravity downwards toward the center of pressure by adding weight to the bottom, or move the center of pressure upwards toward the center of gravity by reducing the size of the fins.
