Gotcha.I was talking to those that won't fly if they can not use a large motor or hit 1000s of feet. They will never fly LPR.
Their loss!

Probably a lot easier to find than standard Quarks and other subatomic particles!I have an Estes Quark that I fly at small fields. The difference with this one is that it features a 6" plastic streamer attached to each fin with Kapton tape. On an A10 -3T motor it turns in a very amusing low altitude flight and recovery. Very fun bird to fly!
Depends on the precise design. Some BT-20 rockets like the Hi-Flier will clear 1000 ft on C motors. While the drift distance can be manageable, visibility is another thing to consider. If I were trying to keep that thing low, I wouldn’t go bigger than an A.At our small local launch today, on a small field, we had very light winds. We get a lot of less experienced flyers sometimes, flying things like BT20 rockets on B motors, maybe even C motors. I was amazed how many small rockets with streamers landed within 25' of the pad.

We had numerous little rockets that were out of sight until ejection and there was a sparkling streamer to see, and many of them came down near the pad. I launched 3 rockets, 2 low-fliers, and they both landed pretty far from the pad in the tall weeds. We had almost no wind for much of the day. I made a mistake connecting the streamer in my Baby Bertha and it separated from the rocket at ejection. The rocket came down safely in the tall weeds but was difficult to find, the streamer came down on its own and landed about 10' from where the rocket landed.
One thing I noticed when comparing the small fast rockets with bigger slow rockets- the small fast rockets went mostly straight up to apogee, the bigger slower rockets tended to deviate a little or a lot when they came off the rod taking them farther away from the pad. I don't know if this is because they were slower and not stabilized as well by airflow, or because the 1/8" rods can't guide a heavier rocket as well. If there was more wind I would have wondered about that, but we had almost no wind today.
What is a "JLCR"? I'm guessing a "Jolly Logic Chute Release"?Not going to rehash some great tips already given. I like fat and draggier stuff for small fields, but adding in a JLCR makes for more altitude easily without worrying about drift too much. BT60 and up will be needed though (although I've heard people have gotten them in BT-55 rockets successfully). Also, sticking to rockets you know will go straight up helps as well.
Picking the right time of day and wind direction matters. We will hit our local park in the mornings before wind picks up. It's not a huge field, and has a nice group of trees on the south/middle part of it. But, things like the old Alien Space Probe on an E12-6 with JLCR works just fine or Big Daddy on some composite Es are doable. We routinely use the JLCR on this field and then use guidelines suggested above to enjoy quite the range of rockets.

I like that Twin Factor.Here is small fleet of fun to build rockets which (mostly) fly no higher than 100':

A field the size of a tennis court should be plenty big enough for these models.
Sounds like the description of a fat lady and her husband.....Short and fat with lots of base drag and a high thrust short duration motor.
The Apogee Atomizer has a ring around the fins designed specifically for that purpose. It’s permanent but if you can produce a reliable attach-detach method, that’s not entirely out of the question.Right now, my interest is in scale or 3FNC/4FNC rocket designs, so Oddrocs are out as my primary style of build.
I've decided to stick with a BT-20 rocket focus for now, but I'm also going to build a BT-60 rocket (perhaps the Estes Patriot). I also think I'm going to do some experiments (eventually) to find a way to turn a "regular" BT-20 rocket (like the Viking, Yankee or Wizard type of rocket) into a temporary high drag, "low and slow" rocket. The goal is to keep a low altitude (75-200 feet), but have a lift off that parallels a Big Bertha as much as possible.
I'm leaning towards doing something proposed by @David_Stack earlier in this thread. Maybe some sort of cup-shaped ring that I can stick to the fins for low-and-slow flights, but easily remove it for the next flight if I so wish.
I haven’t dug into HPR yet but my guess would be that the noise of a bigger motor and the sight a high flying rocket makes in the sky is one many admireI could never understand the fascination of watching a model rocket disappear in the blink of and then watching in rapt interest as the model descends on whatever the chosen recovery method is. Give me low and slow, so I can watch the entire flight from launch to touchdown.
I think that uses an Estes Patriot nose cone...I think.Old thread, but it occurs to me that the Curvilinear is pretty much designed to answer the OP's question.

Also the cheapest source for that nose cone if you want to use it for something else.
