Hey guys, i figured i'd do a scratch last minute for the April LPR contest, and do NOT ASK WHAT GAVE ME THE IDEA Anywho, this would be a good time to see if this is basically a spool, if not, i am in big trouble when it comes to stability....... Anyway, here is a few pictures after completion
He'll need 2 of them (fore and aft) for it to preform like a spool rocket, otherwise, it will fly more saucer-like with just 1 larger endplate.You'll need to add at least one end plate for this thing to be a spool rocket SD...As micro said, you'll need at least one endplate for it to be stable. As is, it's just a cylinder, and that won't be stable.get a nice big clear plastic end, so as not to ruin the look, and you'll be fine.
Hey Scrapdaddy, good post!
This might work for an endplate, for both ends.
It's that clear plastic cover from a blank CD package. You'd have to cut off the longer side wall, but at the top it fits a new roll of T.P. perfectly! Being clear, you only see the toilet paper roll fly.
The top of the cover (in the picture, the toilet paper is sitting in) has a clear lip that surrounds the edges of the roll.
Now, on to recovery. At ejection, try to get it to unroll (without tearing) like a long streamer.
Buit don't throw out that cover just yet...To cjl,
You're right about the endplate. I stand corrected!
I just thought it was interesting that the CD cover fit the width of the TP roll.
SD's Flying Roll of TP was done as an entry in the April "Should Not Fly" contest. I think that it is, in fact, a daring idea. I have seen toilet paper incorporated into any number of odd-roc designs, but I have never seen anyone ever try to make a complete actual roll fly without any obvious structural augmentation, like fins or an added airframe. Now I can't tell for sure from the video, but it looks like the roll, with that motor at least, was stable during the very brief boost. It was also seriously underpowered and was not technically a kosher flight because it came in ballistic without any means of slowing its descent. So what it needs now is some structural augmentation to allow it to be stable with a more powerful motor. This will allow it to be boosted higher so that it gets a real flight and also so that it can deploy a recovery devbice and make a safe return.
I have a couple of ideas that might work for that.

Well, first things first, you were all wrong when you said it needed an endplate, [YOUTUBE]_lW8p8-y1K0[/YOUTUBE] And finaly, it utilizes Featherweight recovery It was marginaly stable on a "A" motor, i have yet to try it on a "C"
More likely it was so underpowered on an A motor that it didn't have time to go unstable before the motor burned out.
Umm...
Heck no.
Where does it say that you must eject the motor and the weight limit for featherwieght?
