Does any one know the diameter of Thermalite?
Any sources for it anymore?
Good sources for ready-made igniters: https://www.frankumperformance.com/starters-and-initiators https://quickburst.net/unregulated_products.htm
I have been out if the loop for a number of years now. Has there been a change? Back in the day Thermalite was used for any thing pyro firing, lite by a e-match. Also there was only one flavor, red I think was the color.
In case someone has some handy to measure it might be good to specify pink, green, or white.
So if I under standing what you all have been saying Thermalite is no longer available in the USA? If so what is it replacement if any?
All the same. Gonna say 1/16"
The replacement now days would be a small light weight timer/flight computer wouldn't it? A Raven would be able to do such a thing with extra safety lockets based on altitude/velocity/etc no?
That's what I am working on, flight computer. The problem I am having now is finding a igniter that fires with 5V@~1Amp. All the igniters I have seen so far require 12V. The firework e-matches, I found on Ebay ([url]https://www.ebay.com/itm/E-match-100pcs-lot-11-81in-For-Fireworks-Firing-System-Electric-Igniters-display-/131738535564?hash=item1eac3a868c:g:6S0AAOSwzgRW0qS4)[/URL], do not burn long enough to light a upstage engine.
If any one knows of such igniter, please let me know.![]()
How big are these pyrodex pellet?
It is a three stage bird. The first stage will be 9977M2245-P and stage 2 & stage 3 will be 2645L265-P. That is if I can find a low voltage iginter. I am going to test the firework e-match and a Pyrodex pellet.
