What would happen if it goes out of site and then comes back in a few minutes latter and lands nearby? Would it be when it lands or first goes out of site?
First goes out of site. Your scenario is highly unlikely, when it's caught in an updraft big enough to carry it high enough to get it out of sight, you're probably not gonna see it again.

What's a typical time (mid-pack for a competitive state) for a backslider? If you know, I'd like times both with and without a parachute.

Backsliders seem to peek out in the high 20s lower 30s, if you got really good I might foresee 40s. Egg o naut times should be similar to those that come out of bottle rocket, so you're probably gonna need times upwards of 40 seconds consistent for a win in a decently competitive state.

Wait, then why would you want to use a backslider if the national times were several minutes?

The only reason you would is if parachutes were illegal

I am looking at the Solon parachute. It is really big.
Estimating assuming the bottle holding the egg is 4" dia.:
Inflated dia. = 6'+8"
Assuming perfect hemisphere:
Flat dia. = 10'+6"

Anyone know the actual size?
Was it the largest chute at nats?
What was the biggest parachute posted in this thread?

Thanks to the photographer.
(I think it was Rocketman, but it only credits Dark Sabre so it's ambiguous - could be Dark Sabre or Rocketman or anybody sending it to him?)

I had a 6' 6" flat parachute a brought to nats, I've never measured it inflated (and now I can't cause I threw it out at nats). Neither of my rockets deployed their chutes at nats due to some untested last minute modifications failing, but I was getting my big parachute to deploy consistently in practice. I was never able to get it to deploy that high, but you will see as soon as my videos of some of my launches are uploaded to the image gallery.

From what I saw while they were launching, Solon (which is no los if spelled backward :roll: ) had about a 6' diameter chute, it really wasn't that big.

The largest one that I recall was New Trier, I think it was a little larger than Solon's, so somewhere in the 7-8' range.

Oh OK. I guess that means they used a smaller bottle to hold the egg, so it looks like the chute is bigger.

And New Trier's cone is actually slightly wider than the 2 liter bottle.

I wasn't doing it based on measurements off the image, I was just guesstimating from what I saw at the competition, so I may be wrong.
