twister modification

[rabidsheeep]

i've built a few of those estes twisters but they never seem to twist... they just kinda fall... hard... thats why i have to put streamers on the fins, which limits there altitudes...

im wondering, if i angled the fins a little so on a launch it would spin off the pad up, and spin down, would that work? or just be stupid and dangerous?

i shot my twister off today. went real good.
spun the whole way down.
how do you keep the mmt from shooting out ?
i think i glued it in LOL

That is the way they work. The motor mount with 2 fins come down by them self and the body and 1 fin comes down alone. If you glue it in it will not spin on the way down.

the way i read the instr. it said glue it in
and all 3 fins are gluded to the rocket

Are you talking about the TExas Twister? If so I do not know anything about that rocket. I was talking about the Estes Twister which comes down in to parts. Sorry for the mix up.

i dont recall the twister coming down in two parts? well... of the few i launched at camp one went out of site, one hit the ground rather hard, one i had streamers to so it wouldn't go to high which flipped and swerved and smashed, and the other (this was the funniest thing ever) hit my friend tomas on the head when the engine popped while he was getting his aurora whoes fins snapped off ready... never gonna forget that one...

Rabid,

I think it would work fine. Quest makes a kit called the Spin Fin that works this way. It has 3 fins that are attached like all other rockets, but at the end of each fin is another small fin glued on at a slight angle, to make the rocket spin. Hard to explain without a pic, unfortunately mine was eaten by a tree. Well, caught by a tree, then slowly destroyed by rain, sun, etc.
Let me know if you want more detail, I may still have my instruction sheet somewhere.

Rabid, if you're referring to the <a href="https://www.rocketreviews.com/images_est/est_super_shot.jpg">Estes Twister</a> as found in the Super Shot starter set, then you might have built it incorrectly. This kit is built in TWO sections and comes down in two separate parts, not one. Check out <a href="https://www.dars.org/jimz/estes/est2004c.tif">THIS</a> instruction page taken from JimZ's site of the <a href="https://www.dars.org/jimz/est2004.htm">Estes Tornado</a> (which is essentially the same rocket) rocket kit. After motor burnout, the ejection charge is supposed to separate the lower 1/3 of the rocket (2 main fins and 2 tiny finlets) along with the spent motor casing. The upper main section of the rocket (with nosecone and fin) is supposed to twirl horizontally producing a neat helicopter/star effect. Check out <a href="https://www.dars.org/jimz/estes/est2004d.tif">THIS</a> section of the instructions for further clarification.
