Just a thought

But how long does the glycerin fog last, or is there an alternative that
we could use to produce smoke. There are smoke candles that are used to
detect leaks in hvac systems. These candles burn for a set amount of time
and then go out. The 30 second candle produces 4000 cubic feet of smoke

You'll have to do the redox equations to figure out what volume to burn
for a given temperature.
My plan was to use a high pressure pump and a burn chamber made out of
those heating elements.
I planned on using a 1lb 4A SLA 12v battery which could double as
ballast anyhow and just let us fly
a larger motor.

Probably the most massive amount of smoke can be made by using a fogger
nozzle like the below:

And simply inject it in the burn chamber.
You'll run an inlet vent on your nosecone right through the burn chamber.
A new "modern" smoke with no nasty chemicals.

But, I wonder how much of that stuff you can atomize.

The tracking smoke I used before I once got it to smoke on the way up,
but we need to do this
to at least 10K' AGL to even see anything worth while.

And we'll want to shut it off on descent to prevent fouling up the
recovery gear.

Here's some stuff to look at:

Hi Temp Heating Element

Make a prototype and we can figure out how to control it with a
processor.

Oh I understand, if you want help with that, I'd be interested to do
what I can.

Yes, I do have designs for something like this with a pump and
glycerine smoke generator.
But alas, something for next year ... too many projects this year
;-)

Thanks, James. That was very interesting and informative. I
wonder if we can duplicate the tracking smoke on a smaller scale. Could be
interesting.
