Second launch attempt made using home build products to create the next heavy lift NASA carrier in the works. Better this time, but still not the results I expected.
If the stability is marginal as it appears, you can either make the fins bigger or make the rocket longer (not shorter, as you have done in this instance). You might want to take a look at the 'Peak of Flight' PDF series on the Apogee Rocketry website. Lots of good info there - def. help you get your rockets going up straight & high!
There's no need for boosters in a rocket of that size so it is going to be incredibly hard to fly. I can't imagine it every flying straight. All the real rockets that have an odd shape like that have feedback systems that control the flight path, yours has none.
Can't see the fins so well in this video, but it looks like you did put a lot of sweep in them. If you've already moved them aft as far as you can, then you can either make them bigger or add nose weight as suggested by NewFrontierRocketry. Since you wanted to move the CG forward of the CP, shortening the body was a step backwards. I'd keep it at scale length so it looks right, then add nose weight since it's easier to do and it looks like you have adequate thrust to add a couple Oz.
Upon further review, at about T+3 (1:35) it definitely looks like something broke, or an engine cut-off, or maybe a gust of wind. Try it again on a completely windless day.
Have you tried an additional 2 or 3 ounces of weight in the nose cone? In our Mercury-Redstone and Delta shots, moving that CG forward always did the trick.

@Reynasite Yeah I've since realised that. Certainly does look cool though!

@roflex2 I think the idea here is to create a facsimilie of the real Ares rocket.

I recommend sticking to just a single rocket.

Well nice work, too bad it didn't work right. Hopefully you'll have more luck with the Ares I.
