MWJ Posted June 13, 2014 Posted June 13, 2014 This is a 3" long End Burner Rocket. I used 9 grams of my home made water granulated BP with a 1 gr. Flash Powder head. I timed the flight time around 3.68 sec. Thanks guys,Mike J
dagabu Posted June 13, 2014 Posted June 13, 2014 Gotta be proud of that one Mike! The cookies are in the mail.
MWJ Posted June 14, 2014 Author Posted June 14, 2014 Gotta be proud of that one Mike! The cookies are in the mail. Great! Thanks Dagabu. Thanks guys, I have another one to shoot off tonite. I put 3 red stars in it and want to test it when it's dark outside. I just very happy the rocket didn't go boom before it launched.
MWJ Posted June 14, 2014 Author Posted June 14, 2014 After I finished making the rocket I cleaned out the nozzle with a 1/8" drill bit, turning it by hand. Then the fuse fits in nice too. I was afraid of getting a crack in my fuel while I was ramming it causing it to pop. It's nice when you do something for the first time and it works. 1
redrum Posted July 18, 2014 Posted July 18, 2014 That Rocket looked great. I hope to do my first here in just a few weeks or so. Got to get set up first.
dagabu Posted August 4, 2014 Posted August 4, 2014 MJ, add about 4" more of stick and use wood glue to adhere it to the motor. The flight will be a lot farther and straighter. I am bringing a dozen sets of 1/2" rocket tooling with me to PGI, anybody can come to my table and make all the rockets they want. I am open to selling the sets as well to get back my materials cost. The sets I have now are for a full 4" tube, a whole inch longer than the MJ is using. That is a full 3" of BP that will burn for about 9 seconds of flight time.
MWJ Posted August 5, 2014 Author Posted August 5, 2014 OK, I'll try it when I can light rockets off again, thanks Dave. Have fun at the PGI!
