Yes, tons of them - here's a couple of quick examples, theres plenty more out there you can find with a little web research:

a) Not always - that's mostly a problem of the past- use a good modern one and "forgeddaboudit" :)
b) if your expecting freezing cold, then don't use crappy caps. duh! ;)
c) Come on- how much mass...
Quoting myself here:
"the point is there is no disadvantage in using a better regulator and no advantage in using a poorer one."
The other advantage if using a 'modern' regulator is low drop out, which is a major plus in avoiding a MCU brownout condition, especially if the battery is of questionable freshness, when firing the...
Thats correct.
6/8/10g is more than enough to use as a simple G-switch to trigger timers, but not for integrating acceleration and trying to detect apogee from that, unless its a very low-G rocket...
Just thinking out loud- it may not be very scientific -
i just thought that would make an interesting looking rocket. Leaving small gaps and square edges, all the same - the fly it and see if it...
The specs are listed in the manuals which you can download on their website: http://www.picoalt.com/: 40,000'
Most barometric altimeters top out between 25k and 50k feet.
Above that, air...
In general, you get better range at lower frequency, and narrower bandwidth.
Video is inherently wide bandwidth, which doesn't help either. It just means you need a more powerful transmitter.
Depends on the size you need, but these are the lightest for their size:

there are other sizes, they...
Ok here's a little teaser for the MMX crowd:
i just got the last of the component samples that i was waiting on, for the smallest device i want to do.
I couldn't resist lining up all the key...
Ok, so i'm thinking it should be made to fit in a 29mm airframe.
Does anyone feel it would be really useful to have a GPS tracker smaller than that? If so please give some examples why.
I'll be...
Thanks for all the replies so far- keep 'em coming!
Ok so so far, the sizes picked are pretty even across the board.
I wasn't expecting that at all!
Especially on the low end of the scale,...
Well, looks like the people have spoken - IRDA is out, USB is in.
Ask and ye shall receiveth :)
Too bad though, i thought IRDA was a kinda neat idea.
Maybe i'll keep it in the design, there...
Wow and i thought i was slow!
I only started mine around 1981 (give or take a year)
If i could get replacements for some of the lost little styrene bits, i might actually finish it this year......
Now look what you've done!- i cant get this idea outta my head;).
Oh but i think i've come up with a great recipe idea for the rocket-pie:
2 recycled aluminum foil pie plates (preferably 3.14159...
Whats next, root-two day? :p:rolleyes:
That gives me an idea for an oddrock- a flying pie-rocket!:D
Now the tough part- deciding what kind of pie- Boston cream, blueberry, or pumpkin? or the old...
One word: UPSCALE !
:cool:
Yup, she's definitely a keeper!:)
What are they made of? plastic or ceramic?
Great find guys!
LOL usually i'm the guy going off to do some quick web research to help some poor lazy or lost soul on the forums, but i was feeling lazy this time- nice to know it works the other...

Thanks, i just wet mine.
I tried that on my L2 rocket using 0.062" G10 fins and a 1/4" gap.
whistle was barely noticeable. i suspect you need thicker fins and a wider gap for it to work. i'm curious if anyone's ever worked...
I was thinking about this recently- I occasionally hear third or fourth hand about some of the great things people are doing with model rockets in our schools and how wonderful it is such a setting...
A wile back i tried grooving my centering rings the width of the fin tabs to make the fins "self-aligning".
Its actually quite easy, and makes assembly stronger and idiot-proof, an important...
What is more relevant to question at hand, is
If both are packed inside identical, strong and well built rocket airframes, they will both be about equal in lethality and damage-inducing effect.
END-burners ! :rolleyes:
^^^^^^^^
Thats what the 38mm G69, I49/ I59 are- no hollow core, 100% filled from nozzle to delay grain with that magical propellant :D
Total volumetric efficiency, by...
Does the motor have to be a J-350? I'd fly it on an H & I motor first, use the altimeter data to calibrate the sim's in rocksim, and run some sims with different J motors and find one that keeps you...
Well as long as we're all wishing out loud......
Jut curious, did ya ever give any thought to doing some 29mm W9 end-burners? 29/40-120 would be excellent or 29-180 or longer i'd love that too....
Like for most things in life, i'd say it depends....
what size fins, motor, total weight, parachute ?
Polycarbonate (lexan) is nearly unbreakable but very flexible for the thickness compared to...
Any construction supply store- home depot etc 2' x8' planks up to 3" thick
don't get the expanded bead type, the homogeneous kind is much better for this.
