Will it fly? Sputnik/Odd-Ball Thing

Postby Aquaman33 » Sat Mar 09, 2019 6:22 pm

My youngest son wanted to make his "dragon's egg" fly.

So I have turned it into this Sputnik/Odd-ball style rocket.

It weighs 50g including the parachute.

The egg is about 90mm tall and 70mm across at the widest part.

The legs made from 5mm styrene tube and are 245mm long.

I am thinking about flying it on an A or B motor, but I have no idea how to sim it.

It looks okay when I eyeball it, but that's not very scientific.

Does anyone have any experience with these things?

I could easily make the legs longer and/or thinker if required.

Cheers,

Derek

Nice :)

Looks like it will be stable to me, but you may want some extra distance to the launch pad on the first flight just in case...

Don't see why not. Just ask the Kiwis.

Thanks for the feedback.

To be safe I added some 9mm diameter leg extensions. I think they will add a reasonable amount of drag.

I'll post a photo when its finished.

Photo of it finished with purple leg extensions.

And the inside.

Plenty of room for shock cord and a parachute.

Should be an interesting flight!

You could nick-name it "Spudnik".
