Unfortunately up here in good ole Canada getting any type of rocket motors or "explosive" device is not easy. Most dealers in the US will not ship to Canada - been there tried that. I've sent out a few emails to see if anyone will....
Even our LHS have a really hard time getting anything "exotic" - pretty much just the standard Estes stuff. I can get Aerotech E's and F's but not plugged and that is getting a little high powered for this application - last thing I need is a 8lb kick in the pants of a delicate balsa stick frame!
If you have any links to anyone that will ship to Canada please post
