My son took some great photos of mine at the last SARG launch.

I think paint and I have an uneasy truce going.
Very nice quake, tell your son he did a good job.

I'm especially proud of this shot. My 1/6th scale Mercury Redstone on an M1939W and four K550Ws at Red Glare XII. 135lbs on the pad, and flew to 5,775'.

This rocket isn't pretty... it's one of my 4-H kid's rockets, on its first and only flight. We launch them in primer, so that damage can be more easily repaired before the Fair. But I liked the liftoff pictures; the first set was taken by my wife, the second by Bob Benton of the Canton Camera Club (to which we also belong).
This rocket, which Justin named "Stripin'" after his planned paint job, is 5'7" long. When I described the design on YORF, I was told it would never work; but he built it, and it did in fact work just fine. It's flying here on 3x E9-6 engines, and a simulation in OpenRocket says it probably made it to 1,300' feet or so. It certainly looked like it did. The parachute is a 52" aluminized mylar octagon with braided shroud lines epoxied to the shroud. Justin ran polyester (magic transparent) tape around all the edges to protect against tearing.
It drifted a long ways. Apparently, the chute was too big. What can I say? It's twice as big as the biggest rocket any of us had ever flown... we didn't really know what we were doing. But OpenRocket said it would fly, and it did.
There's a video of the launch on my website here: http://rocketry.gonnerman.org/launch20110619.html

No matter how much you push the envelope.
it'll still be stationery.
This may be a dumb question... But why wasn't there an LES on the 1/6 Mercury Redstone? Spectacular rocket, by the way.
Oh, and my lift-off pics are coming. They're not as impressive as most of you guys', but I've got a coupe interesting scratchers.![]()
what did you do to it?
Rockets are like women.
You love yours until you see someone else's
Short answer, I didn't want to build one. Long answer, with 5 large motors, a large amount of noseweight was necessary. The whole nosecone weighs 36lbs. There was just no practical way of flying it that wouldn't result in some form of damage to the tower, and I didn't want to have to build something that I would just have to repair after every flight.
You missed a very detailed discussion about this topic last year. The thread has since been lost, but that's the gist of it.![]()

Love this shot that Neil McGilvray captured of my Gizmo just after clearing the pad at Red Glare XII

I love America but I also love Canadian bacon, whiskey, and MOTORS.
Here's a couple of mine.The tall one is my "got milk"and the other is "red matter"both on a C11-5 for testing.My got milk did alright but very under powered needs at least a D12 the red matter did good but only 435'...research,research I love it!

What about putting a small (D-G class?) motor in the LES that's activated at apogee? The motor pulls the LES away from the rest of the rocket/nose cone at apogee and then either motor-ejects a parachute to bring it down safely without damage? Who cares if it's the most stable thing in the world or not, you just want it to be separated from the capsule. You could even use the altimeter used to "airstart" the LES motor at apogee to 'dual deploy' aka let the tower tumble until 1000' or so and then deploy a parachute to recover it safely?
Obviously it's totally up to you, just seems like a cool extension project since you've proven the rocket flies
