l2 success

Okay so I put a buck and a quarter into the pot on this one Congrats aagain Jim.

We got a flight of a j350 for a L2 cert which DID NOT FLY AS DESIGNED (a weather c*ck at 100 feet)! (a L2 SHOULD have a feel for how a bird will perform given the weather and winds!)

This bird with this motor should have been in the range of "1000's of feet" in altitude....

What if the bird had gotten hung up on the pad and only made it to 100' and then popped the chute and landed next to the pad? It's the same as this flight. Would that be a a valid cert?

This clearly wasn't a valid cert, and all the folks that claim it is, clearly have never really read or understood the cert requirements. A PML Endeavor on a J350 at 100-200 feet that weathercocks?

I'm dumbfounded at the number of posts from those who think is was a good cert! Maybe that's why the NAR BOT has his new thing about range safety.. Too many weird flights.

The vast majority of high power rockets I've seen either did, or could have, weathercocked depending on the conditions. That doesn't make them unsafe.

Who said it didn't? The original post doesn't mention the maximum altitude. 100 feet was the approximate altitude at which the rocket began to weathercock. Are you so quick to jump to conclusions that you missed this fact and assumed that the rocket never cleared 100 feet?

No, it is not the same, since there is no reason to believe that this flight only made it to 100 feet. Perhaps you should pay a little more attention to what you read and be a little less quick to jump on people.

Well Woody, I'm dumbfounded that a seemingly bright guy like you can't read well enough to know that "the rocket weathercocked at 100 feet" does not mean "the rocket only made it to 100 feet".

I would think that with your experience, you'd also realize that any J-powered rocket that only made it to 100 feet would have impacted long before the ejection charge fired. Even if the rocket somehow made a 90 degree turn and went horizontal, it still would have hit the ground before popping the chute. In fact, Jim's original post states that after apogee the rocket went "down and down and down". That sure doesn't sound like a rocket that went horizontal or that only made it to 100 feet.

Amen Ray,

Incidentally, I reported witnessing a FatBoy with an E9-4 yank a launch rod off a multiple pad. Went up about 100', turned 90 degrees and the rod fell off. The model streaked off and I could appreciate the ballistic drop as it travelled horizontally. The ejection fired about

40' off the ground, chute deployed and model recovered unharmed. Man did some rmr people rant about this one. This was at my first TRA event run by some very qualified individuals with five flight lines Estes up front and one M pad "way out there". So a launch rod got loose. Sure you don't want to see that happen but this sport cannot be totally risk free. The rod was replaced and secured and there were no other launch mishaps. In fact I can't recall witnessing a recovery system failure. If this was my model on a cert flight and it behaved like the above, (would have to different model of course) I would offer to reload and do it again. This would be unlikely to happen 'cause I'd probably use a rail and a heavier pad. :)

Nothing in the links look unsafe to me ?

In fact his post about down, down down describe many flights I see with delay issues, and the fact once recovery was activated by the ejction charge his rocket was un-damaged shows good recovery device techniques IMHO.

I don't know, Ray - this sounds just like the AZWoody I've read here on RMR for the past six years or so...

A complete and total perfect idiot who is more than happy to jump headlong toward the first conclusion that graces his pea brain.

Do you have friends, Woody? I'm wondering who would choose to hang around with a downer like you.

Jim, Congrats on the cert. Don't listen to Woody. He's just a pant-load.

Pathetic.

G. Harry Stine would be rolling over in his grave

I have two questions for you:

  1. Why would he be rolling in his grave over a safe flight?

  1. Why should anyone care?

I can't answer #1, but I can answer #2. Animated zombies should be the concern of all God fearing people.

According to "Shaun of the Dead", the undead can be put to good use doing menial labor, or used on game shows.=20



Good movie!

Oh, You mean like on Family feud.

He wasn't shocked by much. He was a rebel.

Hmmmmmm.

Jim,

Congratulations on your cert flight. Don't worry about what other people say. A very small portion of the folks that frequent here want to criticize everything. It gives them the illusion of power and superiority.

I know on my cert flights all of my rockets went off a straight vertical flight pattern. I think it was called apogee :-)
