Estes Cosmos Mariner - what to do with it ;-)?

[Skyfall]

As I know this is a special favourite of yours, this might be a bit of fun

I bought it as part of a bigger package, together with other rockets, as I liked the theme and shape.
Knowing well that gliders can be quite tricky, but without having investigated furhter at that point in time.
Then afterwards starting to investigate what I actually had bought, the full (sad) story materialised quite soon.
But hey, now that I anyway have it, question is what to do with it - suggestions welcome!
And as I started the "poll" I will give it a start:

1.) keep it seald and put it to the bin
2.) build it with as little as possible efforts and go for an expected one-off launch on the green field, with no spectators at all, me wearing safty gear
3.) build it with attention to detail and make it a shelf-queen
4.) ...

Now you

P.S.: Anyone around here got it seriously flying?

As you might know most of the flights on the rocket reviews do not sound good.

I built one. Got it to glide a couple times, out of several launches. It can get done! But it's unlikely.

Build it really nice AND fly it. That's what I always do.

 

[ljwilley]

Or give it to me.

I had the Estes SR-X, which might be similar, flew once, and have not gone back to it.

Thanks for that link - indeed looks kind of similar.
And I didn’t know of that one!

If it was mine, I would build it and fly it. Most of the reviews that I have seen noted that it was heavy and underpowered so I would build it light and perhaps use a larger composite motor.

I have an SRX that I purchased built but not painted. I plan to finish it up and fly it when I get the chance. I will probably launch it with a Quest 18mm composite D when I get it done.

Not really possible to save any weight in construction the molded plastic parts are heavy and clunky.

Built it, flew it, crashed it, binned it, moved on.
Unfortunately I have another one waiting in the wings. Anyone want it...?
Cheers

Convert it to RC.

…

That is somehow what I realistically expect here as well.

… next to the bulk of washers, I suppose…
Indeed quite a weight-burden.

I think I will just give it a try with the (here easily available) Klima D9-5

So it is confirmed that it has certain glider abilities !
Thanks for sharing

Build it, fly it, love it! It can be done! The few, the proud, the Cosmos Mariner flyers! Post a successful flight video and vanquish the fears of all the haters, who are many.

[Skyfall]

Of course I need to give it a try
Promise to come back with some evidence as and when, but that will fore sure take a while, just started two other builds.

And that was an Estes D11-P which may be a good match for the Klima D9, though maybe a D9-3 instead.

Skyfall kept the Cosmos Mariner. It should have ended that day, but evil was allowed to endure...

 

[Back_at_it]

I built one. First flight was a disaster as it weather cocked badly then weather cocked back the other way. Motor burned out and it tumbled to the ground with no harm done.

Added a little nose weight and got a better flight out of it but it still incredibly susceptible to any minor wind. Again, tumbled to the ground and landed it tall weeds. Took a while to find but no harm done.

Never got it to glide, never really got a good flight out of it. Gave it to a buddy before I crashed it. Hated everything except the build. The build was kinda fun

Though still a great appearance and silhouette In flight!
Maybe it‘s just only made for the way up (with no winds)?
