I buy rockets due to their altitude which estes model goes the highest?
If they still make it, probably the Commanche-III, 3 stage 24mm to 18 to 18. I think it goes around 2000-2500 or so.
Other than that look for smaller 18mm minimum diameter kits like the Sizzle, Hi Flyer, etc.
The Comanche-3, but I would not reccomend it for you. It is a challenging build, and if not done right, can easily crash. If all you want is altitude, a Sizzler or a Star Dart will easily go out of sight to 2000 feet or so.
Probably the Sizzler, unless you want to stage, in which case the Comanche-3 probably takes the cake. I could be all wrong though.
The Wizzard gets up there too. Min Dia 18mm.
Good luck getting it back though!
Had to be the Estes Alpha that astronaut Jay Apt took with him on his first space shuttle flight.<g>
From the 2004 Estes catalog:
Wizard 1500' on C6-7
Yankee 1400' on C6-7
Viking 1470' on C6-7
Star dart 2010' on C6-7
Sizzler 2040' on C6-7
Hi-Flier 1690' on C6-7
Commanche 3: 2660' on D12-0, C6-0, and C6-7 (three stages)
Long out of production, but the Estes Apogee II is definitely capable of 1/2 mi flights. Very high performance payloader!!
I have seen some clones and freshly-built originals (who would do such a thing?) on ebay for sale, so there are some around.
Launched mine a couple of times in the 80's and it went out of sight on B14-0 to B6-6's. C6-0 to C6-7 would be insanely high!
I may just have to scratch build one just to try that!
Here's my original built about 1979 or 80.
How about making one from scratch? You can make a homebuilt rocket that is cheap, easy to build, and will go higher than any single stage Estes kit ever made.
Get an 18" length of BT-50 (0.976" body tube), an ogive or parabolic nosecone, some 1/8" balsa or basswood fin stock, a thrust ring (an 18mm to 24mm centering ring will work), a 24" piece of kevlar or elastic for a shock cord, and a streamer (crepe paper like is used for party decorations is great for this). Cut out 3 fins in a 30-60-90 triangle shape (make them kinda small), glue in your thrust ring, install the shock cord, glue on the fins (with the long side on the body tube, pointiest end up), tie on the nose cone and streamer. If you have built a few other rockets this will be simple to do, but if you have not get a rocketeer with a little experience to help you.
Put in a D12-7 engine and let 'er rip. Sometimes it helps to put a single layer of aluminum foil around the engine, this will help to keep the paint from bubbling up from the heat of the engine. Lots of folks don't even paint rockets like this one, 'cause they are likely to get lost anyhow.
It has to be the Mosquito, mines still going up!!!
Good idea pkmpd about the scratch build using all Estes parts.
Can anyone Rocksim that build and see how high the projected altitude would be w/ a D12-7? How about if you CHAD staged it?
I think everyone would be interested to find out. I know I would.
Glad I took the time to read the responses. I knew someone would bring this up. (And if you hadn't, I would have. )
Modified Patriot on a F21-8
I think the Eliminator gets 2000 feet on an E9, single stage. Beyond that, the Commanche III. I love mine!
My favorite high altitude, single motored ESTES model is the old Sprint.
Here is the Roc-sim for a BT-55 version (the older one was 28mm, this one will take an E motor!!) The Rocsim gives an altitude of 2680 feet!!
I have enough parts laying around for a few more BT-56 versions of the Sprint.
It's sort of an SEMROC SLS version of the original.
Including some decals too!
For an OOP Estes kit the Farside would probably top them all, small 3 stage Rocket which would top out at a half mile. Of course I had to try the C6-0, C6-0, C6-7 combo on it. That explains why I don't have it any more (well still have the first stage booster). If i had used a streamer I might of had a chance to get it back!
Its not Estes, but Mystical Rockets has something on the design board that is a 3 stager that will do 3100 feet on 18mm motors.
(Ok, Mystical Rockets is me. Working on getting all the prototypes built and tested right now. 2 down, 8 to go.)
The long OOP Esturi Tiger Streak/Apache 2 would really go high, especially if you converted it to 24mm and used a D12-0/D12-7.
I have built and flown the 'Sandman Sprint'... It is one of my favorite rockets!!
I use a 6" x 60" streamer for recovery, and even then.... it goes up, and up... and up.... and up....
Then comes down slowly....
I love it!!
Since I have no idea what your building skills are, I would suggest the Comanche-3. If you have built at least 2 or three models that require the fins to be glued on individually it is not that hard of a build... It just takes a little longer. It is one of our best selling Estes rockets in our 3 stores. It has been purchased by many modelers of various ability levels and no one has reported that it has "crashed"... Flown away out of site yes, crashed no.
The Astron Farside...built properly it will top out just a little
higher than the Commanche (how about converting the Farside's
first stage to a D12-0?!). I have an Astron Farside "still-in-the-
bag" awaiting assembly.
For single stage kits, the current Estes Sizzler is hard to beat; my
son had one and we flew it successfully several times on the
C6-7 for really eyeball breaking flights (even got it back after first
giving up for lost!). Finally lost the Sizzler at the 2004 Remax
Ballunar Festival at JSC when it simply vanished on ignition...even
with several hundred people looking on, no one could see it.
Since it was my decision to use a C6, I had to buy my son another
Sizzler to replace the lost one (got a Sizzler/Star Dart combo at
a local Wal-Mart for less than $5!).
I think what some meant by "crash" is what I witnessed at NSL -
2004 at Hearne, TX; one young rocketeer launched his very nicely
built Comanche-3 that failed to stage (D12-0 to C6-0) and it
lawndarted. Apparently the pressure of the D12's gases forced
the stages to separate before the C6 could ignite. Similar thing
happened to my Estes Cineroc/Omega in the late 1970's...(yes,
my Cineroc got smashed).
Why does Estes change their max altidudes? You figure they'd get it right the first time. In the 2006 catalog The Yankee is the highest single stage at 1850 ft.
If you're an experienced modeler, you could scratch build a rack rocket, 3 and 4 stages, or more if you were really an altitude freak...There was a post on this not too long ago, like others have suggested do a SEARCH.
Something that happened at one of the earlier Whitakers launches I attended was a D12-C6-B6 Commanche. Booster and second stage went fine, but the sustainer (3rd stage) wouldn't light. It started to come in ballistic, and about 1/3rd of the way down the B6 lit and shot the whole upper stage into the ground.
Needless to say, there wasn't much left of the rocket.
I've had a comanchie 3 that had the 1st stage stick to the second, completely toasting it. But this was my fault, and i'd definatly reccomend it, but do something with non-plastic molded fins first.
Sounds like the novice stuck a C6-7 in there instead of a C6-0 not knowing the difference. Heck, the label on the C6-7 even says for upper stage. Maybe they need one of those "this coffee is hot" warnings advising against using in anything with another motor above it.
