If you never intend to fly 75mm, then build it 54mm. That way you can later find a killer deal on 75mm hardware and wish said hardware would fit in your glorious Big Nuke.
I said I would never go above 29mm, then 38 was big enough. I now have a 76/3600 that I got a killer deal on. Though I don't have a rocket for it yet.
Go 75mm, adapt down and then when the planet's align and the weather gives you the thumbs up, light a 75mm candle in the thing and smile. :cool:

Do you recommend dual altimeters for this Loc 3E for redundancy since it appears that 75mm motor fore closures are generally plugged and will be no motor ejection for back up?
 
Stick with the 54mm MM, if you've only flown 38mm so far there is still a heck of allot between 38 and 54 to fly. Are you L2? 54mm you still have J, K & L's I'd say Fly 5-10 of each of those in 54mm then move up, heck a 75 2G Case and closures cost almost 350.00 and that's without the motor. Just no need to rush is all.
 
After all was said and done my 76/3600 (75mm 3grain) cost me about 70 bucks, including shipping, snap rings and so on. Add in the hubcap I got for 40 I think, and a spacer I picked up for a few bucks, I can fly any CTI or AT 75mm 2 or 3 grain in the one casing. I can grab a nozzle and fly Loki, Gorilla, AMW. I'll have to fly em research but I can handle that.
Like I said, killer deal. Sometimes things work out just right.

But yes, lots of fun to be had in 54mm, including the Loki M1378.

There's been some debate on the the forum about back up and redundancy, and others more experienced than me may disagree, but IMHO at our Level, you should double up on altimeters wherever possible, if space allows, as it does with your build. I learned the hard way. Of course you can fly a single altimeter with motor eject as back up, but that's not always practicable, depending on the flight profile. But in any case, there's considerable G forces at play on any HPR flight, and a switch can be shaken open or terminal block connection jolted loose. E-matches can (occasionally) be dud. I tend to mix and match altimeters so I don't have two of the same brand in the same Av bay (eg an SLCF as primary set for drogue at apogee and main at 700', paired with an RRC2+ set to fire at apogee plus 1, main at 500'), but that's just a thing I do. Two charge wells on each Av bulkhead.
 
With the Missile Works RRC2+ at 44.95 not much reason not to go redundant. My redundant altimeter just saved my rocket 2 weeks ago as one of the apogee charges didn't ignite due to a faulty battery. Rocket would have been coming in ballistic while popping the main.
 
I only have experience with one altimeter, the Stratologger CF so others probably work differently, but I’m wondering how it works just prior to flight when you have two altimeters in the same rocket. You turn the first altimeter on and go through the beeping sequence and then move to the second altimeter and try to listen to it’s beeping sequence over the first one that’s still beeping telling you it’s ready for flight?
 
The RRC2+ has a selectable tone so each altimeter has 2 different distinctive tones. Its pretty easy to hear the difference in each.
 
For my L3 certification flight in 2000, I used two different brands of altimeters: 1 Adept altimeter and another one that I can't recall the brand name for. Tim51's comment is spot on about mix and match.

But if you build the rocket for 75mm, you'll never be first in line for the screaming deal on the case. You'll click on the thread in the yard sale and five people will be there ahead of you. :p Plus if you do get the screaming deal, you just have to build another rocket to fit it.

I'm also a fan of redundant altimeters where they fit. Saved my bacon a couple of times. The small, simple, and cheap ones are good for this (RRC2+, Quark, etc.).

Yep. And two or three of those five will already have multiple versions of said case already. :confused:

I agree on redundant altimeters. I fly mostly Mssileworks stuff, inexpensive and simple, the RRC2+ at least. I like Eggtimer but I occasionally have issues during assembly.
 
I agree. Why not have redundant altimeters if you have plenty of room in your eBay and can get a secondary one inexpensive. Plus it makes the build a little more challenging.
 
I wish there was a mega nuke 4e. I'd crank that sucker on a O if I could keep it below the waiver at Potter.....

I'm sure I saw a 98mm MMT version on Loc's website a while back although it seems to have disappeared. It was called a 'Big Nuke 4', iirc (..?)
 
It’s still there but you it gives you three options under the Nuke. There’s the Big Nuke classic, the 3E and then the 4. You have to click on the one you want and then it gives you pricing.
 
I want to use 26,000 newtons.....my O9700 but it's gotta stay below 20,000 feet.....
 
Can’t believe the Nuke 4 isn’t fiberglass. Can you actually fly 98’s without glassing? Maybe the kit recommends glassing.

Surely. A 1 grain 98 is comparable to a 2 grain 75. Just more weight concentrated toward the aft end.
 
Thanks Steve, I haven't flown my Big Nuke in 6 years but with all this BN talk I'm going to fly it in 2 weeks at out METRA launch lol
