Re: Another mighty initial thrust idea
As much as I hate having to resort to one of Rupert the unbearable's publications:
"Gotcha" :-)
Troll calling the kettle black - heh heh heh...
Now down to specifics: The vast majority of results from a youtube search for 'amateur rockets' show successful launches; sure, you can search for unsuccessful launches (additional keyword "fail"), of which there are, and must be, some (mostly accounted for by the aforementioned home-made nozzles and motors), but the vast majority of amateur unguided rocket launches do not display the kind of instabilities that you profess to be inevitable, despite your professed experience of 'having built over one hundred, and designed over thirty' rocket powered vehicles.
Are you now going to try to divert attention away from the issue and on to incorrect punctuation?
Oh yeah - NO NEED TO SHOUT!!!
