Hello
A few weeks ago I built a Wacky Worm, called Knexy http://www.sscoaster...ers/knexy-r1613 . Now I've taken it and I'm redo it with an instant launch after the terrifying 1st drop! So I already built the launch, Top Hat and a a few curves on the tower.
As launch system I'm using something similar to a jesper launch, only that the train activates the launch and I need to pull it back by hand. Overall the launch works fine, the only problem were the rollbacks, because the always broke the chain, so I added anti rollback dogs between the launch and the top hat.
Soon I'll continue with it...
Now some photos:

Can you make something like a tutorial? I've tried so many times to create a launch but it always broke and this seems like an excellent launch to use 

And I think I have got the parts for it.

Well, I´ve never made a tutorial before but I could try it. You just need to wait a bit since I´ll be back home on sunday.

It's hard to tell, but it seems like the whole structure would shake during the top hat from the force of the launch. There are not many supports. But who knows, I may be wrong! I like the launch alot!

Thanks It isn´t really shaky, but I need to add some more supports to the curves after the top hat because the car isn´t making it right now...

A small update after a week:

I've continued with a bit of trackwork and I put the train new together, because one car isn't going well and always slows the train down. The next things I'll be doing is continue with the trackwork, so I planned to make a loop after the drop and then probably a barrel roll back to the station. The other thing, or let's say problem I have is the launch because the train won't go up anymore at the full stretch of the rubber band, but before it went well, so either there is too much friction on the launch-chain or the rubber bands are just streched too much, so I somehow need to find a solution that this isn't a big problem later, instead of changing the rubber bands every week or so.

Below I have a photo of the top hat with the new turnaround and drop.

PS: Do you know any tricks that the "braking car" isn't braking anymore?

PPS: Sorry that I'm not getting forward that quickly, school's very busy at the moment!

Do you mean that one car is slowing down the rest? Because in that case I would just not use that one if I were you.

Yeah, that's the case. I'm not using it right now but I was wondering if there is something to get it back running normally. (Maybe some oil for the wheel or the connector between the front & the back of the car?)

[K1ngdaKa88]

Today I managed to get the launch back working properly. The mayor problem wasn't the rubber band, it was that the launch released too early, so the train lost some speed. So I moved the piece which releases the launch a red rod down the launch and I changed the settings of the rubber bands. Before it was like this:
=---
But now it's like this, so it has more power:
==--
And I've done some trackwork as well. I've finished the large drop and built the loop and it works pretty well.

I have a testing video on Twitter: https://twitter.com/...393508370710528

And some photos:

This piece I moved down. It's the one the train pushes forward, so the rope gets pulled back.

The rope gets moved down to the purple rod, which gets pulled up to release the chain so the rubber bands can release theirs power.

And the loop

And all from the back.

As soon as I have time again I'll continue with it. I'm planing to build a barrel roll after the loop to the station.
What do you think of it?

Very inventive layout and the launch seems to work pretty well. I do like to see a coaster with crazy winding track every now and then. It reminds me of how I used to build.

Thank you. When the launch works, it's working quite well, but the chain snaps often during the launch or while pulling up.

Silicone spray works very well to get your cars running faster. If that one car is bad I would just not use it though. Silicone spray probably won't help it. For silicone spray I usually spray some into a cup (the cap works too) and then I take a super thin paint brush to put the silicone spray in between the wheels. I recommend before you do this you clean out your wheels,
You can just take a little napkin and clean out the axles of the wheel that way. Also if you haven't already you should weight your cars. Since you fave so many cars I don't think you would need to weight them though.

As for now, this car is not in use, but I still want to bring it back to use. And thanks for the tip, I'll try this out.

Yesterday evening I've finished the trackwork. The last thing I added was a zero-g-roll. I made some testing and it works well. Also the launch has less problems than on the before. The only thing I wanna do is a better station.

And do you have any suggestions to make it even better?

I love the uniqueness of the ride. It's just so much fun to look at, and the different colored track pieces really make it stand out. I, as well, think you should also make a better station that is more noticeable.

That's nice to hear, thanks
As soon as I have time, I'll start with the station.

[K1ngdaKa88]

I now made a station, well, just a platform and a roof, because I'm not very good in building stations. As for now I would say I'm finished. So now I just need to shoot the video, edit and upload it. Depending on how busy school is, it may comes this Friday, but it could also take a few weeks.

Fantastic job on this - well done!

I love the randomness of the concept and I think you've managed to execute it beautifully as well - that instant launch really does exactly what it says on the tin (and it's powerful too)!

You're definitely improving with every model you make and this is no exception.  The pacing, shaping and strength of the coaster is excellent.

 

What I admire most is your dedication to the build in a time where there are very few members, especially micro builders,around to critique it. Keep it going!
