Man whatever you decide, and you know Mark is QUICK, it looks AWESOME!!!

So when do ya fly??

Unfortunately, not for a long time. Most likely LDRS in July.

JULY?? no way Id be like a kid in a candy store.. could not wait that long to fly it!

Looks good Jello!

Thanks Jim!

I'm thinking maybe something like this:

Man you did an awesome job. So how did you like the metalcast paint?

It's not bad. It would look much better painted over real chrome I think.

 

[Wayco]

Great job! I like the accents you added at the bottom of the body tube too.
I was gonna suggest you fly it on a "G" motor first, but looking at the thrustcurve data for my DS Jr., no way would I fly anything that only goes up 300 ft. !

 

[Coop]

July? You've FAR more patience than me. I'd be at the very next launch.


Later!

Love the post, that is ONE GOOD LOOKING ROCKET!

Love the purple!

That is insanely cool. LOVE IT!

 

[Aksrockets]

Really Nice Finish GJ! Well documented build thread too!
When are you flying it?

[Green Jello]

Unless there is a local launch I can go to sooner, it will be LDRS in July. I don't really have a local club here.

 

[Worsaer]

Snow Ranch is a long drive for you, but much sooner than LDRS...

That's where I want to put my 10" Goblin when I finish it. I'll tell her Green Jello's wife let him put his rocket there.

You should display art prominently!

 

[cbrarick]

I see what the problem is. It's the stuff behind the rocket is distracting and doesn't match the rocket. Perhaps if you get rid of it, she will appreciate the rocket more :wink:

Springfest. I know Vegas is a haul from Reno. .

Yeah, that's a long drive. If I was going to one I guess I'd look into the Snow Ranch one. That is about 3 hours from me where Jean Lake in Vegas would be about 8.

Hey Bill, is this the site for info on the Snow Ranch launch?

That's old, they haven't launched at Robertson Park for some time now. The Snow Ranch launches are the first Saturday of the month from November through May, fire danger permitting. They have mid power launches at Moffett/NASA Ames the third Saturday of the month, pretty much year around.

Ok...time to resurrect this thread and talk about what motor to certify on.

I'm gonna keep it simple and not involve dual deploy for the L1 cert and just do motor eject I think. So I need input on these two questions:

1) Do I fly the Wildman Jr in short mode, or the whole thing and just have the main chute in the lower section?

2) What 38mm CTI motor should I get?

1. It's entirely up to you. I'd just fly the whole thing.

2. Depends on wether you want it to go high or not. The H100 IMAX is a surprisingly cool motor in my opinion, but it looks like you have 9 choices, thanks to your spreadsheets

 

[Green Jello]

Not sure what you mean by this. Correct me if I'm wrong, but L1 is total impulse between 160 and 640 NS. So if you filter the 38mm engines in CTI for that, it gives you 29 motors.

H123
H143
H400
H120
H125
H110
H225
H152
H100
I180
I212

[Wayco]

How much did your Jr. end up weighing? Mine ended up at 74.4 oz. Thrustcurve estimates the smallest H for mine would be the H143 Smoky Sam to 1229 ft.
I have one flight on mine, but it was an AT I161 that went to 1995 ft. That's about as low as I would go with it DD.
You should fly it the way you like, not rely on our suggestions. Plug your data into Thrustcurve.com and pick out a motor that does what you want for your L-1 flight. Logic would suggest that "short" mode would be simpler, and therefore better for a cert. flight, but I would never fly mine like that, it's not what I built it for. I built it to learn dual deploy.
If you ignore my advise, and take my suggestion, fly it on a I180 Skidmark and make a statement!

 

[Getmore]

I would go with the H100 also with the main in the lower section. That will make for a good L1 cert.

 

[Green Jello]

Well of course I'm going to make the final decision myself, but I wanted some opinions. I was thinking of keeping it on the lower side (about 2000') for the cert. I was thinking the H225 or H152. I think I will fly the whole thing together and not worry about short mode.

 

[Jmhepworth]

I'm making the same decision except with a 2.6" fiberglass DX3. Having just smashed up my first go at level 1 when the rocket became unstable, I'm going with the DX3 with DD and an extra 16". I plan to launch it single deploy using the engine, but I'm going to keep the extra length to make it more than stable. I may make some other mistake this time around, but not the same one.

He can't fly before LDRS -- he's stuck letting me see this one, in person.

[Aksrockets]

Don't be afraid to put a 3G motor in it. I've seen a few DarkStars (including my own) on 2G motors. They really don't go that high.

Cool 2G motors IMHO
H123 Skid
H400VM
H100IM
H225WT

Cool 3G motors:
I180SK
I566VM
I175W
I345WT

I'll be at LDRS, so I can get good video and pics of the flight!

Excellent! Please post them, afterwards.

You could try the new 5-grain moonburner I125 White.
