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.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
