I will be using a

new launch on a recreation to a shuttle looper, which is similiar to the one used on

shuttle loops of the 70's.
I will use the RR car attatched to a string that

goes through 5 pulleys on a tal tower. I will use either weight or I will simply use my

own force as a ripcord. The RR car will push the SS car very quickly through the

launch run, through the loop, and up a spike, and it will come back and the RR car will

slow and stop it. I hope that this is an original Idea.

ka-ching!

That's why, it is the name for it as well, Reversi.......
As for CC10's

comments in RCT the trains will be themed to look like a twinkie. I might even change

it to the Twinkie Deep Fry Oreo, instead of Reversi.

I have done a Shuttle Looper but it had to come down,

even though I was waiting for this tutorial by coastergeekrct, shame but it was fun

launching it :D

Good luck, and there are some excellent videos of the launch here- http://www.atguide.p...ueyonder.co.uk/ and information on

Schwartzkoph Weightdrop launches here- http://schwarzkopf.c...elooptyp1GF.htm

The video and information is based on the Thunderlooper at Alton Towers,

which now resides in Brazil.

I have the same question as nyteflyte. Are you going to

let the rr car just be pushed by the ss train for the whole ride? I'm not sure how

you're plan works, but it sounds great so good luck. ;)

no, it will stop after

the last pulley and the SS train will continue thru the loop up the spike, back, and if the

string is long enough attatched to the RR it will have a back spike. This will go

adjacent to Fanblade to save picture space and it will have some cool together

pics........

Hmm, I am not liking the sound of that, the RR car will

stop the SS train dead in it's tracks. Perhaps consider not using the RR car, but

instead a couple of chainlengths to haul the SS car, then these can go below the

track.

No, the RR

car's BEHIND the SS car, then the rr will stop at the end of the last pulley, but

momentum puts SS thru the loop, up the spike , and back until the string on the RR is

taught.

Yes, I know, but then when the SS car returns, the

collision between it and the RR car will stop it before it has a chance to reach the end

spike.

, no, the string to

launch it will have a lot of slack, so it will come back anyway and come up it a bit.

I know exactly what you mean, but read

carefully! I am saying that once the SS train hits the RR car on it's way

BACK, the collision will take all the momentum out of the SS car and it will stop

dead! Therefore it won't get back up the rear spike!

it wont stop dead,

it will keep going, it has slack on the string, its not like its wound to the tightest strength

it can handle.since it will be at the end of the string, when it goes backwards it will

automatically rewind it to save time. it will work, and if you dont understand that, i will

have pics up later.

God, it's like talking to a brick wall that can

type with you sometimes......

I know EXACTLY what you are wanting to

do, but I AM GIVING YOU A WARNING. As soon as the SS car hits the RR car

on it's way BACK from being launched, the collision will take the momentum

away even if there IS slack. That means that both cars won't get up the back

spike.

I give up. I really do! Right, for the LAST

TIME-

I KNOW WHAT YOU MEAN. I know EXACTLY what you are

on about doing Dak! Now please LISTEN to what I am trying to say!

When the SS car comes back after being launched, it will collide with the

RR car which is on the launchtrack. This collision will remove the vast majority of the

energy that the SS car has- it will slow it down very much. This means that no matter

how much slack you have got, the two cars will NOT make it up the rear spike, heck

they may not even make it to the station!
