I would like to know if an alpha, wizard rocket can comply with 6 in parachutes.
Body tube wise would be nice to know.....

But would a 6" support a alpha rocket flying on a 1/2 A6-3?
or would it be better for a smaller rocket like Viking or Wizard?

Tagging onto this, WHAT is the goal for your recovery device? Sounds like in your case, you may want to swap out a streamer for a chute. WHY?Matt,
The simple answer is yes, a six inch parachute can fit into those rockets as long as you fold them correctly and use a chute made of the right fabric. But that’s not how chutes are matched to rockets. You match them according to the weight and descent speed you want.
Also depends on what your launch fields are like. Mine are usually pretty soft farmland, so I err on the side of smaller chutes, except for designs more likely to be vulnerable to landing damage (i.e. APRO Lander II).2. Will the device slow the rocket down enough that the rocket doesn't break? A lot of this depends on rocket design, particularly fins. Airfoiled fins, rear swept fins (classic Alpha), and fancy fins and landing gear (Mar Snooper), anything built by @neil_w , may benefit from a larger chute and a softer landing than something like an Estes Viking built with fins swept FORWARD. (my bias is showing, I LOVE forward swept fins both because they look cool and because when rocket lands usually the motor casing hits and takes brunt of impact before fins get involved with the ground.)
That is exactly why i am asking more experienced people, who have used 6" parachutes, I am preparing the team for up coming comp. . I wouldn't say its a bad thing to ask questions?Matt, you've called yourself a 'rocket commander', 'team leader', and 'rocket expert/wiz' in several previous posts on here.
Taking into account the very basic questions you've been asking also, I think you need to study some more on the fundamentals of rocket design and rocket performance, as well as gain some experience using simulation software before you call yourself any of those again.
You will benefit from the research, as will any team you find yourself in charge of.

Yes, they do exist. Pulled one from my spare parts pile. I think it came with a mini engine RTF kit, but don't remember which one. I probably subbed a streamer for it for faster pre-flight prep.In all my rocketry. I have never used a 6-inch parachute. That is very small. How many grams does your rocket weigh?
I would like to know if cutting a spill hole in a 6" parachute would defeat the purpose of the chute, when used with a Alpha Rocket
I cut spill holes in most of my plastic chutes to stabilize descent. In this case you are taking a tiny chute and making it tinier... but if a smaller effective size is OK then go for it.I would like to know if cutting a spill hole in a 6" parachute would defeat the purpose of the chute, when used with a Alpha Rocket
Yeah for my Competition on Sep 21st we are required to use 6" parachutes, when all our gear is fitted with 12".
Yeah, they want 6" I was questioning the comp when they also wanted 1/2A6-3 engines, but a competition is a competition and we abide by the rules... Just fyi these are competitions held and run by AFJROTC Units, they have at least 3 NAR refs there...I am not familiar with a competition involving 6" parachutes. I know about duration competitions using the biggest streamers or parachutes one can fit in a rocket, but the idea there is to big, not small.
Ill get a PDF for you to look over, Ill also try to share some pics of recent comp i went to...Maybe that's why I've never heard heard of it. I am not versed in any JROTC competitions for rocketry. Do you have a link you could share?
