this is a video on how to make a fast chain lift for a knex rollercoaster. comment rate make it and subscribe. make sure that the motors are the same and make sure that all of the batteries are the same voltages. it goes fast because the big gear is attached to the motor and the small gear is attached to the gears that drive the chain.

  • great vid. 5/5 just two questions,are those medium sized gears or....idk. and the second qustion is were in the world did you get that many connectors to hold the gear in place???i have about two and i have bought many knex sets such as a screaming serpent.

  • if you mean the yellow ones then those are the largest gears that you can buy(I think). I got the connectors from the medium and little sets that they sell at toys r us. Normally the sets will have a picture of the thing that you build in the set and get the one with a picture that has some gears and you will probably get lots of connectors and gears if you buy a few sets.

  • do they have to be black motors?? i only have one of them!!!

  • they dont have to be the black motors they just have to be the same exact motor and you have to have two.

see all

  • How do you put the chain on?

  • Nice. To make it more realistic, you should make the dog system that produces the clanking/clicking sound as the train goes up the hill. I'll explain it if you want. :)

  • @wazupimaskater What if you use a green motor? Will that make it slow? I have 3 green motors o.o WAIT I wanna try to put all of them on! Oh wait, one has no batteries. o.o Ok I'm gonna try now lol.

  • I don't have spare parts from my other creationes so... I was wondering which set would be the best for this.

    Also, how could you attach a coaster to it?

  • Yay! It works! one suggestion though, could you please say what parts are needed at the beginning?

  • it goes faster because a big gear is spinning a little gear. if it was vice versa it would be slower

  • how do you connect your coaster car

  • thanks for the instructions it will be in my nex coaster
