Great memories. Every visit to my grandpa he had a new Estes for me to build. Big Bertha was the most successful! Never lost her. The little ones always disappeared in a field. I started bringing the mini rockets to school to build when I was bored.

Back in the mid to late 90s at Glamis, me me buddy Chris and Ken the Giant had the brilliant idea one drunken night around the campfire to set up the launch pad of an Estes rocket in the bed of Chris’ dark green metallic Chevy xtra cab half ton and crack a chemlight open and drizzle some glow in the darkness juice on the rocket before launch.

And up it went! We watched where it landed and looked down.😳

The bed of Chris truck looked like a murder scene under black light😂
Took the 3 of us 20 minutes to clean that shit out of the bed of his truck.

Years later when Ken retired and moved up to Oroville I bought a CT90 from him and a few nicknacks out of his garage on his way out.
He threw in the Rocket kit with a few engines and a couple size rockets.
Sat in my garage a few years. Then
See post #19 👍

This thread is bringing back So many Great memories! 🤣🤣🤣

Would a foorball field size area be big enough for this Rocket? It says it goes 1100 ft high. I am thinking shooting straight up with no wind.

A football field would be fine for this. Just make sure there’s little to no wind. The C engines will go up to 1100ft, but it’s also under parachute for 1100ft and can drift a long ways away even if there’s no prevalent wind.

The A and B engines are great and the rocket will come right back down where you launched from. We’ll go and get 3 launches in 15 mins that way.

Buy an extra parachute and packing material. I keep everything in a small tote so I just grab that and the launch pad and go.

We launched the Rocket with success The question I have is about the Motors. I do not want it to go much higher due to the space we have and the wind. But I am willing to chance it if they wont go much higher.
We used an A8-3 Motor I have some B6-6 Motors and some C6-5 How much higher would the B Motors go? How much higher would the C Motors go?
Thanks everyone for the tips. As you can see my kid and the neighborhood kids loved it.

When I was younger we would launch rockets at my elementary schools football field. A few ended up in trees in the neighborhood near by.

Each motor series is a big step up. Id say you are going about 500 feet or more higher with each series, but this is all variable depending on the rocket size/weight and engines burn number.

The C's are really great, best bang per buck as a hard lawn mowing kid.
The mighty D is a real thumper so powerful it can tear rockets apart.

One of the things you can do to make recovery less of an excursion is shorten the burn # and extend the ejection charge time by getting a motor with shorter first numbers and longer second number.

In other words the first number is (or was) the newton seconds of thrust, and the second number is the delay between end of thrust and the ejection charge - you can experiment with a larger engine incrementally by playing with both variables.

When I was a kid two companies ruled - Estes and Centuri. Each has its own pluses and minuses.
My wallet was spent mostly on Estes, with my favorite being the relatively short for the power Red Max powered by a D12-9. This thing exploded off the pad and vanished into the sky.

...but my heart belonged to Centuri with aspirational rockets like the SSV scorpion.

The estes engines were cheaper and had a wider range of variables, but the estes ignition system and the igniters that came in the engines packs were garbage, so you had to upgrade to the premium igniters.

The centuri ignition system used a 12V lantern battery and instantly lit off any sized motor where with estes we basically used cheap cannon fuse vs igniters.



Have fun, I wish I were there.
There is something primally fun about a rocket that is unmatched by just about anything.

We didn't have much money growing up, so for us, it was old paper towel/toilet paper/gift wrap rolls and hand-shaped balsa wood nose cones and fins. Or we scavenged/recycled plastic nose cones from other kids failed launches.

We would make the motor mounts by layering/molding paper, soaked in Elmers glue, wrapped around a used motor. It was super fun, learning thru trial and error.

We built our own launch stations, too.

I hand-built a bitchen rocket shaped after a Nike Ajax missile...man, I wish I could share pics of it. It came out great.

I guess we just weren't happy with anything out of the box, except for the motors themselves. 😁

Awesome, cheap hobby.

Congrats :)

This stuff was expensive as a broke kid especially when you split the money between rockets, gas and 2 stroke mix.

The A & B don’t seem too terribly different, obviously the B goes higher, but it’s not usually a PIA to recover it. The C is a whole nother animal, it’s noticeably higher and much more prone to drift under canopy. When you light off the C you’ll know it lol, it burns a long time.

As a teenager I built an E engine Estes kit once that still used the cardboard tube. It would crumple the tube on every launch and go sideways, fly 1/4 mi away lol. Fun times but starts to get real expensive real quick when you’re broke lol.

Model rocketry was a class in 7nth and 8th grade. The good old days.
Back then it was universally accepted that B's are a waste of time.
Nobody built rockets with B's (except totally new guys that didnt know any better)
The local hobby shops didnt even carry the engines. It went A,C, D.

D was the top end when I was a kid.

The E sounds exciting.

if they are drifting to far under canopy, you can tune the parachute. i can remember my dad cutting holes in the chute to make it come down faster. start small and work up on the hole size.

Before you chop the chute lengthen the ejection charge so it falls farther down before opening.

Hard landings break things.

lol! If you got one good ignition out of 10 or 12 attempts, you were doing good!

Ive got a 50 year old scar on my pinky from starting cox 049's.

In one place they call it a jet, in another they say it's a rocket.

What is it? Whats it run on?

My favorite one was the space shuttle. Little foam shuttle would disconnect and fly back on its own while the rocket came down on parachutes. There was also one I had with a 110 camera in it that would take a picture when the chute fired. Lots of cool memories. We had a priest at the Catholic Church who would buy our rockets for us and have us run out at the end of mass and fire the rockets when people walked out after service. He loved them. 😂

CAMROC Baby!

Way to much bread for my broke ass.

Lawns were getting 5, plus a bone or two tip if you were nice and clean.
Snow removal a full sidwalk. steps and driveway 8 (hoping for a 2.0 tip)
Cheap old fuckers always wanted you to do snow for a 5 er.

Mom made us take care of the widow next door for free (shed comp gas but not time) year round
(chapped our asses but instilled a sense of community)

We once successfully launched a multi stage model. Did it at a large playground. Thought we had plenty of room. We unfortunately watched the largest stage experience some chute failure and saw it semi crash land on the roof of a nearby home. Fortunately, we knew the people, and watched them rush out of the house. We immediately went over to them (mostly to recover that large portion - a hallow cardboard tube about 3ft long). The home owners were amazed when they saw that’s all it was. They said it sounded like a 747 had crashed on their roof.

The worst launch we had as kids was the rocket that landed in the center divider of the 118 freeway. We rode our bikes over to the elementary school and launched a D rocket on the field. We thought we were good, thankfully, it didnt end up on the actual freeway. My buddy asked his sister if she’d drive us to go get it and she told his parents and that ended our group model rocketry for a bit.

I ended up building a rocket car out of an old Tamiya Grasshopper RC car I had. It had 3 D rockets with a working chute. My dad thought that was cool. I also took a Ninja model rocket with an A motor, some 3” drain pipe, and built a Stinger Missile shoulder fired rocket launcher (my dad worked for General Dynamics and was the project manager on the Stinger Missile project). I shot it at a neighbor kid and that didn’t go over well..

Good Times

It’s a rocket. Solid fuel pellets ( I forget compound) fuse you feed in the nozzle to light the fuel. I attached them to various vehicles with limited success. Best was worth it though.
Made a glider. Solid balsa type with clay on the nose and a real airfoil solidbalsa wing. Walked miles. To the park. Set on the ground a got it to ignite. Skidded along the dg on baseball field and took off.
Low thrust vector with wing lift and it just arched up and looped at about 150’ (?)
I was so excited as it came back around and then “shit run!” As it came right back to the launch area about a foot off the ground. Continuing back up to just past vertical, stalled, and glided across the field.
One of the best as a kid, “ hey let’s put…”
I ever had🤣

So one year I took a few to Parker, planing on loosing them all. I can't remember where we stayed it, but it was on the CA side.

We did a launch over the river, and it drifted right back to us. Score!

About this time...

The park manager comes over to see WTF is going on? He Thought we were lighting off fireworks!

So he casually asks...

What kind of rockets are those?

And my friend, being an even bigger smart ass than me, looks at the one in his hand and says...

It looks like a blue one to me!

The guy goes Fucking ballistic, yelling at us about how Sooopid we are, how we are gonna say the whole desert on fire, blah, blah, BLAH!!!

So I have to be the voice of reason and explain they are model rockets and are completely spent by the time they hit the ground.

He looks everything over, and can see I'm not lying, and tells us, ok, but he wants us to knock it off anyway.

So for once, we Didn't get our asses kicked out. Close though! 😜
