Having played around with my much smaller versions as a kid some 30 years ago... this is really cool!

wow!

what was the record in this launch? was it the massive scale? how big is that thing Mark?

[mojo65]

30 feet tall and 1500LBS as I understand. 10th scale

Rocket Record: The Largest, Heaviest Amateur Rocket Ever Launched
Steve Eves broke two world records Saturday, when his 1/10th scale model of the historic rocket—built in his garage near Akron, Ohio—lifted off from a field on Maryland's Eastern Shore. The 36-ft.-tall rocket was the largest amateur rocket ever launched and recovered successfully—and at 1648 pounds, also the heaviest. Eves' single-stage behemoth was powered by nine motors—eight 13,000 Newton-second N-Class motors and a 77,000 Newton-second P-Class motor. (Five Newton-seconds is equivalent to about a pound of thrust.) All told, the array generated enough force to chuck a Volkswagen more than a half-mile—and sent the Saturn V more than 4440 feet straight up. It was arguably the most audacious display of raw power ever generated by an amateur rocket.

ahhh ic...badass

All told, the project cost about $25,000—including nearly $13,000 for the fuel alone, which burned up in less than 10 seconds. :17428::eek:

I guess it's just something we rocket geeks like to do. That was a nice shot though. For the casual onlooker wondering, 'eh big deal'. Getting all those motors to light simultaneously AND come up to power at the same time is a serious effort - try just finishing the Daytona 500. Now to get that thing to fly straight up and not get crazy - finish the Daytona and do it in the rain on slicks. Finally getting the parachutes to all deploy and everything else to work right - run the Daytona on ice and finish on two wheels.

:youaretheman:

Just my thoughts on it. (oh, my best guess not knowing what N motor they used was 4" dia x 48" or so tall - the P should prolly be 5-6" dia and closer to 5')

and then to land straight up and down...PRICELESS!:sifone:

Kinda like you landing on a wingtip isn't it?

BTW, when are you flying next?

Went last Sunday, crashed two planes without ever starting an engine........

wind gusted and flipped one over on top of the other damaged both....:508:

Just go carve out a couple others out of plywood. ;)

Seriously though, that sucks.
