This kit includes all the bits required to turn a cardboard tube into a real rocket. Well except for the actual rocket fuel.
There is a fair amount of variation in the size and quality of paper tubes. The nose cone and tail assembly are based around a 40mm diameter tube. I ended up using these tubes from Michael's Craft Store. But with a bit of luck, glue, or tweaking the scaling in your slicer toilet paper or paper towel roll tubes should work as well.
I would use PETG over PLA. PETG is less brittle and is more likely to survive landing. On the topic of survival, these seem to survive being launched on a c motor without issue so long as the parachute (or streamer) deploys properly and the rocket doesn't find a tree on the way down.
The random calculator I found on the internet has the following flight predictions:
I have only flown this rocket on C motors, as they are the only size I have on hand. I did not measure the maximum altitude, but it seemed plenty high and roughly inline with the internet's predictions. I would not fly this rocket on an A motor for obvious reasons.
I recommend the following print settings:
You will need the following for assembly:
Assembly itself is straight forwards and should be self explanatory, but feel free to message me if you have questions.
Update 4/11/2024: I added a single piece guide. The pair of smaller ones works, but they are a bit finicky to get aligned and have minimal surface contact to glue to the body tube. This one piece version is a bit more robust.
