"PSII" 2.5" Nike-X Design and Build Thread

[DigBaddy]

Are you computing the CP on the red dot between the two main fins? I'm winging it a bit on mine and woud have guessed that the CP was a bit forward of that. Thanks.

I'm trusting OR on this one; I suppose I should learn to calculate CP manually. It seems to be basically in-line with a sim from the original BT55-based design, so it's probably close.

Thanks. Both of my original stock Estes Nike X's, had a flight CG just forward of the middle fins. Conservative is likely the norm for the masses.

Good info. Thanks.

Cardboard cutouts still work. We used them back when a "computer" was a person with a lot of numbers and a pencil.

Got the decals on (stickershock). Just clear left. Turned out ok, I think.

Came out very nice. Bet it'll be a great flyer!

That looks fantastic! Any motors picked out?

I'd have to dig into OR, but I suspect the first flight will probably be an F50-6.

Hope to see it at a Bong launch.

If anyone else sees it, that'll be the place!

Finally had a chance to fly this rocket and it went about as perfect as a maiden flight could go. F52C-5. I totally failed at the video, so hopefully you can believe there was flying between the before and after photos. This thing will be really nice on a G64....

Wonderful!

it was too nippy for my blood. I did a still run instead.

Definitely not the warmest day to fly, but we had fun anyways.

Good to hear. There have been years when I’ve gotten in some good winter flying, but this isn’t one of them.

Lack of snow cover sucks. We'd have flow a lot more if we had snow but since we haven't, we've not once went out on our lake to fly. Glare ice is just busted fins.

Come on Estes, release this one!
