Estes "Mean Machine" model rocket ... FAIL!

[JMChladek]

I did that once to a Cobra 1500 (a 5 foot tall 18mm motor powered rocket) and I got it to do something similar with a A8-3 loaded in it (lowest it called for was a B6-4). ;) As far as D failures go, that is a freaky one.

[david1513]

ok that was a motor failure not a motor mount problum plus the rocket has to much weight for that engine it needs a F size engine, you blew the nozzel out of the engine by it being to close to the ground you need 12 inches from any thing under the rocket a clear blast area under it, 12 inches from blast plate, has to do with a shock wave under the rocket motor its close to the speed of sound, the shock wave will crack the nozzel, on card board rocket motors, clay nozzels will crack from shock,

[AcepilotC172]

That was a D12-5?? Although granted I have had problems with the D12-5 in the past where it ignites and then blows up. Not sure why that is.

[saluteshell5]

i have a modified mean machine on my profile i desined to spin on the way up ill post it as a vid responce

[SuperBvd]

CATO, everybody has had it, good luck next time!!

[SQUIRALBOY43]

LOL! *laughing so hard i piss my pants*

[LoopyZag]

the was such a f****** FAIL

u guys DO NOT know how to launch model rockets

[sonicfan1234100]

BIG FAIL NOOB

[UKairsoft94]

@sonicfan1234100 you cant talk you play with toy rockets

[metermatch]

That wasn't a problem with the motor mount - that was a CATO- that was a motor failure. Kind of looks like the nozzle blew out the back.

[crazybastard82]

odd that it came down almost on top of you...did you piss off the rocket gods recently?

[thiswomps352]

Hahahaha. That might be true. I've set off a lot of rockets, and to tell you the truth, I never had a successful launch and return. Something always goes wrong.

[stratorat79]

@thiswomps352 Just a thought, the key word that stuck out in your description was "rushing". I know how awesome it is to launch rockets, but take a deep breath and plan your construction and launching and you shouldn't have ANY kind of failure unless you have some exotic that has never been flown before.

That said, we all have had a few. Check out my channel for some of my launches. Hopefully by now you've had a bunch of successes and haven't given up. Sometimes, even the failures are fun.

[Zander1494]

I'm building one now, can't wait!

[krustyclown42]

I' building one of these at the moment. I was worried about the card centering rings so I have replaced them with 3mm ply. I've also used expoxy throughout. Hopefully that will make it a little more robust.

[azfyrfyter63]

It's also illegal to use plywood and epoxy on a model rocket.  You need to get licensed and move up to amateur and mid-power rocketry to use those types of components legally.

Model rocketry isn't for that type of reinforcement.

[krustyclown42]

Illegal? How do you figure that?? I still have the 24mm motor mount and will fly it on BP D/E motors. It's still a LPR, just built to last longer.

[lefland]

No, it is not illegal to use plywood or epoxy. I recommend using epoxy rather than glue. Section 101.22 of the FAA laws reguarding model rocketry states that you can use items such as paper, WOOD, and breakable plastic. The only material that is listed which is not allowed is metal, but you can still use metal as long as it is not a substantial piece of the rocket. As for certification, that only limits the amount of propellant that the engines use, and has little to do with building materials.

[starshipvelcrp]

you're retarded, where did you even hear that?

[spoiledworm]

did u use a C motor or somthing!! hah

[thiswomps352]

The motor I used on this was the recommended D12-5.

[spoiledworm]

really

that kinda sucks

[conkeresyn]

Always use the most powerfull recommended engines, sometimes I overpower my rockets which makes it a lot more fun, anyways better luck next time.

[JumpstyleCAPcadet]

@thiswomps352 well it looks like your engine mount wasnt put on right. and u used to week of a motor. not idk what is recomended but go tim taylor and put more power
