PerfectFlite Stratologger SL100

[cbrarick]

Ok, so I'm the luckiest rocketeer around this weekend. I've got the new PerfectFlite Stratologger SL100 to play with before it's released to everyone else. To see it in person you'll have to come the METRA launch this weekend.
So, because I don't have the Ok to release all the details or a picture, I'll just say it's a higher accuracy baro altimeter that doesn't need a mach delay!
Anyhow, mounting it was just as easy as the MWAD. The only difference is that it is about 1/4 inch shorter. you need to drill a couple more holes if you're using your MWAD board. The wiring is all the same: switch, power and 2 outputs.
There's new software that's a snap to use. It's easier then the MWAD software and it allows you to program the altimeter. This one also has a siren to help you find it! The book also says this one will report both speed and max altitude with beeps.

I'll let you know more this weekend - I'm going to use the heck out of it!

Interesting--sound somewhat similar to the Entacore AIM USB altimeter. With the Adept22 setting new $$$ expectations for DD simple altimeters, I am curious what price point this one will come in at even given that it's more fully featured than the Adept22. Did Perfectflite mention a rough idea price range?

With the Adept22 at $39, I'll forego simple download capabilities (AIM or MAWD-like) for anything much more than about $75. If I want oodles of data to download with Mach immunity and more options than I'll ever need, I'll spring for a Raven.

UPDATE, 25 March 2012: I am now flying two SL100s in two, different rockets, have 8+ flights with them and love this altimeter. Although the Adept22 is an incredible altimeter for the price, I really like the SL100's download capability and non-common ground wiring for just a bit more in price. This and the Raven and my go-to altimeters.

Does use a USB connection for downloading the data or does it still need a serial adapter?

Same serial setup....but hey, I've got two, so no problem! Seems to be less finicky then the MWAD when used with windows 7....
New software, too! Way more information. I'll post a screen shot if they let me.

Ok, so that was fun! Went to METRA and who's parked just 3 cars down? The good folk from Perfectflite! Sweet, all your questions answered.
First they have a new retail site: http://www.perfectflitedirect.com/
Second, they are hoping to have this one up on their site next week.
Third, my prototype is not quite what you would get when you order one - so a picture of mine would be useless.
Fourth, there's an amplified speaker you can mount on your ebay....for the siren and it's loud! yousa!

So, I decided to spank the altimeter this weekend in my wildman Jr. I'm a wildman dealer, so you know I'm jot going to throw a G at it. The clouds were right at 4K, so I spanked it with some CTI I spitfires, just up to kiss the clouds, not trying to violate anyone's safety rules. Sunday was higher clouds, so can you say I800 Vmax? Didn't want to throw a J at it because that would have gone straight thru them.
What did I find out? This altimeter is robust, it didn't blink at my attempts to break it into pieces. It beeps out your max speed, so you can LOL with your friends when you bring it back. It's got Red Glare Mach Madness written all over it...no downloading, just let it scream.......
Anyhow. I digress. Never got all the way to mach, but I was close...but no cigar.
So I brought it home and did the download. You don't have to download it every flight, it stores a LDRS load of flights, so no more schelping the computer to METRA. Sure was fun to finally download them, though. I like the new interface, it's a lot nicer. They said that I could post a screen shot, but that will have to wait for another day - maybe wed, because I've got meetings the next two.
They also let me use the smaller, less expensive P-nut altimeter. It logs but does not deploy. I actually taped it onto the side of my stealth and gave it a ride. The J90 was cool, flew mostly straight up and down. you can download this one as well, and the flight profile was really funny! I'm sure it really wasn't designed to be taped to a Applewhite Stealth 54, spinning on the way up and then flipping upside down and spinning on the way down - but it handled it!

My opinion: Nice!

Where would I use it: pretty much anywhere I'd use a baro altimeter - they are some of the sweetest I've seen. I'm hoping the price points are right, so they will sell a truck-load. They're reliable, easy to use and simple to setup.

When would I not use it: Well, I've just gotten into EX and the ARTS2 can help you verify your load (according to burnsim). I've also got a project that must have accelerometer based apogee (the vent holes aren't exposed until the apogee charge happens, but Featherweight said the raven could handle it). That's a pretty picky list, if I do say so myself.

thanks Perfectflite!

I took a peak at this new altimeter and it looks simple as any other Perfect Flight device. The plug in Beeper is a nice touch.


They say that they are working on adding motor thrust profiling to the Raven software package. I just hope it's sooner rather than later.

Oy... They're selling direct, for below MSRP, which means they're competing directly with their dealers.

That's a good way to irritate (and lose) dealers.

Hi,
How much acceleration support the stratologger with a warp 9?
Is the supersonic is ok?
Thanks

[lmt56]

Just placed a order for one.
Hope this model turns out to be a winner.
I own three MAWD's and hate to see the model go.
KISS alt that gets the job done.
I am sure this model will be a step forward but sometime I think, "If it's not broke why fix or replace it."

Has anyone come up with something for the amplified speaker option? If so what are you using?

[KDRaven]

I flew my Stratologger yesterday in my Madcow HV ARCAS that is set up for DD, on a G64-10. The Stratologger reported a 600' flight and at the 400' (I changed the default to this) setting for the mains they deployed just fine for a great landing withinn 100 of the pad. I have not hooked it up to the laptop yet to look at the data.

The locator beacon(sound) is neat. But does need to be amplified some what.

It's just a Baro based altimeter no accelerometer involved.
it is suppose to be mach immune.

Flew a pair of SL100s yesterday at LDRS in a 3"Mongoose. Altitudes recorded were within 3 feet of each other. Drogue and main deployment events ocurred as expected.

Primary altimeter--15,999
Back-up altimeter--16,002
Velocity--892mph

[JDcluster]

I just ordered one 2 days ago and received it today!
I didn't have time to read the manual but, did fire up the software as I already had the data cable from my MAWD.

Looking to fly it at Red Glare.

[JDcluster]

I was able to fly the SL100 at a CTRA launch today.
I flew it in my Caliber EX on an AT I 161-M (which has about 15 flights on it).
Reported a max of 1,974ft and 245MPH

It fired on Q @ 700 ft. (The settings right out of the box)
I dumped the data, just what was reported when it was beeping.
It also shows temperature and voltage.
