Any thoughts or suggestions on what I should do to the roller coaster you think would make it better just tell me and I try to incorporate, change, or add it

Woah. Definitely your best so far. If I'm to be honest, there are quite a few spots where the shaping could be better, but this is still really fudging good nevertheless. You should definitely add a queue line and exit line. Oh, and one more thing: I think this is probably the first large K'nex looper I have ever seen that uses yellow rods throughout.

This is really cool. Good mix of elements and a nice layout. I think if you could just add a little bit to stop the lift shaking so much when it goes down the drop then that might slightly improve it but this is another great step up from you regardless.

This is really nice! It's like a whole level above what I last saw you build! It reminds me a lot of when huge coasters like this were starting to get built like coastercrazy's Diamondback and Nitro recreations. There are some noticeable shaping issues in a couple areas like the entrance of the loop (maybe the exit too if you mirrored it), but it's very impressive you managed to make a coaster of this size with only a couple small issues.

This thing is massive, wow. The shaping (other than a few bumps here and there) looks pretty good. I'm also a sucker for a lot of inversions, here are a few extra brownie points. Overall, it reminds me of that classic K'NEX coaster Minebuster.

The roller coaster stop making the cobra roll! I just re-lubed the trains and cleaned them. 

I don't know what it is but it may be because of the heat its 105 F.

what are your guy's opinions is it the heat or something else? 

[Ghostbuster]

I noticed a big difference in clearing speed with my model. The temperature changed from 82.4 F to 73.4 F. 

All was okay after, wait for the temperature to drop down. Where do you live ?

[frank]

Texas... so wait a few months before the final video, also might be able to showcase this at my school again so might do it then.

I need your guys to help please it has completely stopped making the whole run. I bought new cars and lubricated them with silicon spray cleaned the track so it does not have silicon spray to slide on and it still does not make it. I have video and pictures showing off the part of the track that it does not complete if you can point something out that would be very helpful thank you.

have you tried putting some weights on them?

[frank]

Yes, I have them all weighed with batteries 2 triple-A and 1 double-A

Well things you could do are:

 

-clean the track again

-experiment with less (or maybe more?) weights

-check if the track is smooth (what i do is i put the side of my face against the track so i can see even the slightest bump in the track) and smooth it out.

example:

-do NOT lube the cars again, you'll probably make it worse

-test if there's maybe some cars that are worse than others by spinning the wheels. if possible you can replace them with ones that spin better.

-if you see the track bend in some places try to support it more (i didn't see any spots)

 

i'm just saying anything i'm thinking of..

good luck!

My tip would be to make sure the batteries are very firmly fixed in place or else they’ll just kill your speed. Otherwise check the track for any shaping changes (sometimes a cross tie comes out and kills speed, etc.)

[frank]

Thank you guys for all your help, it now makes it ver smoothly. Sadly the lift has stopped working, I’ve switched the chain twice, made sure they all face the same dorection, fixed all unconnected links, added pully to the top which made it worse I think, and switched the gearing a little. I have run out of options and don’t know what u should do now. Here is a lift showing the lift mechanism and how works. Please tell me any ideas on how I can get this coaster to work agien, because it’s going to be displayed in 3 days as well so I’m running out of time.

[G Force]

Were you able to fix it?  Coaster looks great anyways, love the scale, reminds me of those old-school loopers people used to do before tube supports got big.

[frank]

nope its still broken made 3 different designs which all failed, I think I should make it less steep and go back with design number 1 the one in the video or if you have another idea that would be great.
