Astron Sprint
Sounds like your a "streamer advocate." I remember using them as a kid but, nothing as long as 90." What is your recommendation for folding and attaching? Middle of the 90" forming two- legs, folded according style?
My fear is loosing this new rocket. Even though our field is quite large, surrounded by trees. Last launch had some wind gusts and lost a few, including an "E" powered. Considering a small hole top of parachute too. (Launchers fault cause he wouldn't "angle into wind). Thanks Glenn |

90" Streamer
Hi GH: some how missed this thread when I wrote u about streamers. After reading it, I seriously am thinking about switching out my chute for a streamer. This rocket has a large body tube, so will accomodate it easily. Thanks, Glenn

Streamers, And Nothing Else
I ran into a guy at a local field that I launch my rockets at. We discussed Streamers vs. Chutes. He said that he got tired of losing rockets, so he switched everyone of his rockets to streamer recovery. He said he'll never use a parachute again. In 30 years, I've never met anyone that has chose this path to go down. I would love to hear everyone's opinions/facts on the idea of totally abandoning parachutes. Did this guy make the right choice ? Thanks.

When using streamers for recovery there are two ways to attach:
1: in the middle of the length; provides slower descent due to 2 tails dragging through the air. 2: at the end; provides greatest visibility; thats how I always see my Sprint during recovery even at 1500'+ with a C6-7. Streamer recovery allows one to recover the rocket MUCH closer to the launch point even in high winds. I have used streamers to recover rockets as large as a Cobra-1500 but do not reccommend them on anything larger than about a Cherokee-D or A20 Demon as on larger than that a fin or something usually gets beat up on landing. Forget about them for "everything" as use on a Mars Lander or Saturn 1B (or other fairly heavy rocket) would result in "trash bag recovery" of a "re-kitted" model.

If you fly in an area of thick grass, you will have less chance of damage using streamers. I did the same thing with my Sprint for visibility reasons. It doesn't need such a long streamer, but I packed in the longest crepe streamer I could fit more for visibility than to slow it down.
If you fly on hard surfaces, streamers will often cause impact damage. Then again, unless it's totally calm, parachutes will drag rockets across pavement and cause damage too. Pick your poison if you launch near hard surfaces. |

skybolt
The Estes Skybolt also came with a 90" streamer, had some heavy landings with it but always found it, about 20 flights.

Yep, remember that from the Skybolt well.
Flew as high as the Cherokee-D and Demon on a D12-7, but you had a reasonable chance at recovery due to the absence of a gigantic 18" chute on a 2oz rocket. The streamer in the Skybolt and Sprint were the same in LENGTH ONLY. The Skybolt used a 2"-2.5" wide streamer, whereas the Sprint used a 1" wide streamer. Not sure if it was 2 or 2.5 on the Skybolt, but will check my original when I get the chance.

Parachutes
We've covered the streamers pretty well. However, I have a 51" 3 engine monster. It does have a 24" chute. Two questions: How long should shroud lines be and should I cut a hole in the top of chute?? Thanks
