Estes Comanche 3 stage from smash model rocket club launch

[david1513]

ways to decrease the volum in the tube anybody know how with out causeing a fire? im launching a big kids crayon bank i made into a rocket ill be useing a size G Motor, the weight of this rocket is 24.52 oz or 695 grams its a 4 inch tube linght is 22 inches long, this is with out the nose cone on it,

[jgraham1971]

@david1513 Are you talking about a stuffer tube? A tube inside a tube.

[david1513]

@jgraham1971 no i mean just a outer tube not a ejection tube in side a tube

[david1513]

@jgraham1971 no i mean just a outer tube not a ejection tube in side a tube, ive heard of others says the volume of there tubes was so great that the chute wouldent deploy on ejection , to much mass in that area to eject the nose cone i should be ok others have made a crayon rocket thay had no problums with ejections of the nose cones,

[jgraham1971]

@david1513 I myself would have a stuffer tube such as a Big Bertha has. That way it decreases the volume for the ejection charge and also keeps the recovery and center of gravity at the top.

HAHAHA WE JUST DID THIS IN PHYSICAL SCIENCE 2, haha mine shot directly up in the air and flew into the parking lot from the football field. GO COBBLERS!

[SQUIRALBOY43]

that was a perfect launch!

[hypercoaster11]

when ever i get this rocket, i always lose it because it goes so high lol!!

[Slayer10000000000]

is it hard to build for a 1st rocket?

[SQUIRALBOY43]

@Slayer10000000000 yes

[RCking93]

nice, im launchin aerotech rockets tomorow and i will hav vids on utube soon!

[stomp919]

This fukn rocket rulez!

[Crazymanofskil]

Nice i made one and i am gonna launch mine tomorrow and i hope it goes just as good as yours.

'They finally gave me a window to look out.."

[drugsandsolvents]

no way man your vid looks like the TV launch of apollo 11, I aint being sarcastic, the way the booster ends and the payload continues. Top camera work innit 5 star 4 u (:^D)

[gsaum]

I launched one of these babies on a vacant industrial lot along the Columbia River in Rainier, Oregon back in 1990. We lost sight of it after the second stage fired, and didn't see it land. An hour or so later we were driving across the Lewis and Clark Bridge, and I looked down into the review. Sure enough, a 3 1/2 foot long orange tube was floating right in the shipping channel. That was the first and last flight of my Comache 3. :)

[nootnam]

dang, you dont even need very much pressure to eject the cone. just pushing some engines into estes rockets creates enough pressure and pops the nose out.

[jgraham1971]

Need to get to bed, talk to you soon. Happy building

[jgraham1971]

no it was scratch built.  and my friend Rob's Trident didn't work out. There was not enough pressure to even eject the cone. way too much tube volume.

[nootnam]

thats cool. was that upscale trident a hawks hobby kit? i want to know how all of their baffle designs work out

[jgraham1971]

I have heard of most all launch sites. I am an NAR competitor, team name is The Dark Side. My team mate and I are forth in the country as soon as the points list gets updated. we are going to a national competition in Washington for a week starting on the 28th

[nootnam]

i know, i live in temecula and im gonna join the temecula rocket club soon. they go to rockstock every 6 months and usually go to lucerne dry lake once a month. ever heard of those?

[jgraham1971]

There are 6 clubs in California. If you go to the NAR,org website you can click find a club and there may be one in your area. Clubs are a great investment for use of a good launch field.

[nootnam]

california, their is not much open land out here anymore due to all of the stupid construction, even were we launch now there is construction going up

[jgraham1971]

the upscale belongs to a friend. A member stumbled on it. It's at the Michigan Farmers Hall of Fame in Delton Michigan.

Where abouts do you live?

[nootnam]

no not yet, just launch our own for now. i saw that upscale comanche you launched. where did your club find a 75 acre field

[jgraham1971]

do you belong to a rocket club?

[nootnam]

no, thats my dad. he sucks at video taping. the rocket reached apogee and he kept going up, haha. o well i managed to make it a decent video

the egg survived though and i ate it for breakfast the next morning

[jgraham1971]

Very cool egglofter.  Is that you taking the video?

[nootnam]

ya, ive had a few land on some other peoples trailers and lost. thats cool tho. check out my video its called "NikeX and Eggscalliber"

[jgraham1971]

it may have landed on a trailer. Those flat roofs are a pain to see anything on.

[nootnam]

damn that sucks. you saw it all the way down tho?

[jgraham1971]

No, the sustainer (top) ended up in a trailer park near by and never found.

[nootnam]

cool thx. did you end up getting everything back??

[nootnam]

cool no gap, should i do what everyone says and drill two holes in the top of the 1st stage

[jgraham1971]

there should be no need. Holes in the tube are for pressure to escape. The theory I have is not so much of the altitude increasing the pressure as the speed that it gets to the altitude. If the model reached 2300 feet in 3 seconds I would suggest holes in the top. other then that the model is going to slow for the cone to come off during thrust.

[nootnam]

on the first stage the instructions say to make the engine flush with the back, but the coupler gets in the way and it sticks out about a half inch. is that wrong??

[jgraham1971]

The motor mounts should be flush with the body tubes and the motor should stick out about 1/4 to 1/2 inch. As long as the next stage will not have a gap

I would put the model together minus fins to see how everything should fit first.

[Faralay]

I have to launch one of these in my physics class in a few weeks...Hope it goes as high as yours!

[jgraham1971]

Make sure it is launched straight up, no angle what so ever.

[tjodalv44]

I just launched my Comanche 3 and it flew out of sight and I lost it!! I'm so mad. We were in a huge field too, over 36 acers!
