First build the firestorm freefall knex roller coaster the correct way you need two exact copies of the firestorm freefall coaster
Take three mini cars and connect them all together and the piece that grabs the chain remove that from all cars except the fist car. Now the firestorm ...
Now the lift you take the gear thing and put it in the air instead of nÃ©er the track
Now make an other gear pully same as the last one and pull it back 2 and 1/2 track length and place it. And run the chain
On both sides of the coaster extend the track 2 tracks with the u turn
This is the start of the platform I will update as I get ideas on how to finish this part
One track length and the rest is easy to see
It's is just four mini purple rods
Basically two big triangles
