I have developed my own sit-down multi-pass impulse

coaster.

The forwards spike is a 4 foot 360 degree twisting spike, and the

back spike is straight vertical.

My launch mechanism is not a ruberband, I

find those un-reliable and they only work for a train going in one direction. For my

launches, I use a series of fly wheels to propel the trains forwards and backwards. I

simply switch the direction of the fly wheels spin when the train is on a spike.

photos comming soon.

Feel free to ask questions

IAM CONFUSeD I

NO WHAT A FLY WHEEL IS BUT THE REST IAM CONFUSED

not a real working impulse coaster

IMPULSE COASTER</span>

[BaSeBaLlPlAyA392]

an impulse coaster is built by intamin. regular impulse

coaster are launched by lims and have 2 towers. the front tower (1st tower) twists on

the way up. the back tower (2nd tower) is straight up and has a hold brake on which

grabs the train and holds it for a second. on wicked twister at cedar point the back

tower twists like the front tower. a good example on impulse coasters are vertical

velocity @ six flags great america, wicked twister @ cedar point, and superman

ultimate escape @ six flags worlds of adventure

i really want to see pics of this! how did you get

the wheel thingy? where did you get it?

[Dragon123]

The flywheels system is very simple

basically you use a system of teethed gears...lets say for example, white circular

connector.

u place on connector on a motor, then u place another one

above it, then u place another one below it...so u have a sort of mechanism thats looks

like this VVVVVVVVVVVVVVVVV

the bottom of the V's is a

gear and the tom point where the V's connect is a gear.....

and

basically u place a catch on the car...so the gears catch the flywheels

Sorry but Wicked

Twister doesn't have brakes on the back spike and that is a real Impulse Coaster

[|)ark Squriel_-R-]

well is it like superman

where it goes bacwards up 100 and then falls goes speeding throug the station and

goes up a 100 foot sprail at 100 miles an hour

[Dragon123]

there is no hold brake...the back spike is straight..but i

am really thinking about making it twisted......OR making the front spike at a 45

degree angle like V2 at SFMW

[coasterfreak11]

this is sounding great! i want pics! and i

agree w/ you funky! i was thinking the same thing! cuz you can still have

an impule coaster if it does not have a holding break!

IS THIS A IMPULSE COASTER HERE IS A

PIC

[coasterfreak11]

yes thats an impulse coaster

[|)ark Squriel_-R-]

Thanx Coasterfreak11 i

wasnt sure if it was or not

[BaSeBaLlPlAyA392]

funky,
he said the back spike wasn't

twisted, all of the impulse coasters except wicked twister (basically all that have a

twisted tower and a straight tower) have a hold brake but i may be wrong. wicked

twister has 2 twisted towers therefore ther can not be a hold brake on it

WELL I WOULD

LIKE TO SEE SOMEONE DO THE SUPERMAN RIDE

[BaSeBaLlPlAyA392]

this is what this guy is doing except the superman

ride has a holding brake and his impulse will not

[|)ark Squriel_-R-]

WAHT ARE YOU

TALKING ABOUT

[SSCoasters]

He's saying that it is kind of what the guy is

building except it will not have a holding break like on Superman.
