The only reason it may be flammable is the fact that companies might mix oxygen in to keep people from asphyxiating themselves trying to make their voices higher.A colorless, nonflammable and odorless gas.
Yes, works like a charm. Of course, I am semi-charmed, so YMMVOriginally posted by gerbs4me
when you fly it on E9's do you just leave the red cap off and just tape the motor in?
If only that thin skin could handle the pressure... Could you imagine the power from a tank that size and suitable (inert) reload? yummyOriginally posted by cydermaster
lol - anbody thought of filling the Dude with NO2 & creating a gurt huge hybrid?
Were they decertified before the fire?Originally posted by astrowolf67
I've got a couple of E11-3 reloads, that I've thought about trying in the Dude. But, they aren't currently certified, even though they are producing them again.
Agreed, the Dude is strictly a calm day flyer. Thanks for the calcs. I thought about about doing it, but have had just toooo good of a dayOriginally posted by solrules
yup. Finally decided on doing some calculations to support (or disprove) my helium expierment. Turns out, the Helium would provide a grand total of..........
...... 1.6 ounces of bouyant force. (assuming a 36.1L dude, molecular mass of air to be 29g/m, STP, etc.) That's not even including the weight of the Helium itself.
I agree on not using Hydrogen....it would also not get anywhere near enough bouyant force to lift the dude, as well as being dangerous (I got my data from a somewhat *biased* source )
To get back on-topic, I would suggest not launching the dude under larger power than a D if there is any wind. A small wind gust could bend the *fragile* airframe, and everything would go to heck in a handbasket.
No. All rocket motors have to be re-certified every three years to remain certified. This simply means they send S&T some sample motors, we fire em, and if they have not changed, they pass.Originally posted by iceage
