K500 Amazing on-board video

I know, I know, there's only 13 rockets in the video. That's because the 14th was for the G4 Network's 'It's Effin Science' show and I can't show it until it airs this week. Anyway, good flight, not so straight and as usual, problems with the recovery. I'm sure next time it will work perfectly!

Someone may already have mentioned this, but if your failure mode analysis on the mercury-switch apogee detector is correct, you might be able to get it to work correctly with an electronic "lock-on" on the timer. The simplest would be a magnetic reed switch and electromagnet in series, on a parallel circuit with the mercury switch. When the mercury switch makes contact, the electromagnet would activate the reed switch, thus keeping the timer running even if the mercury switch breaks contact.

Finally got to to work, check out the video "Finally, everything works perfectly...twice in one day"

Thanks!

Dan, you are a true inspiration to Me and my model rocket hobby. After months of failed home trials I bought your book and got the answers I needed. Now we are launching some crazy rockets almost every month. Only problem is finding a big enough field. Thank you again for the book and all the awesome knowledge you post up for us.

Is there anything you can add to the fuel ratio that can give the smoke a color?

[solidskateboards]

I'm sure there is. You should Google it. Unfortunately I don't know though.

Who feels like a fucking astronaut after watching that?!

im gonna build a model rocket with pulse jet technology ..

Yes, it's downtown San Diego. I work there. Thanks.
