Radio controlled rocketry, or any sort of explosive is always a productive topic on these forums. Your middle eastern sounding user's name, really adds some appeal to this sort of project as well. I've seen projects on the web, but don't recall the range, was only curious, but not interested enough to build. It's tough to get this sort of help in the forums, as it's open for all to see, thanks to Google, and other search engines. You might get your rocket launcher built, and safely working (if you survive), but all the kiddies, and anti-socials looking for a similar detonator, really don't need an easy place to get the build details.
Anyhow, unless pulled from the web for security reasons, there were several last year, one using a cellphone...
