K'nex Ball Run - Everest
After six months of building, I finely finished my tallest ball run I have ever built. It is about six feet tall has four paths and two lifts and a lot of elements. The loop with the tightrope running through it was a challenge for me because the ball kept hitting the loop, but I managed to get it to work and the balls never collided when the ball run was running. The biggest lift has huge counterweight on it because it was too much stress on the motor without it, but it stands up very well without it being attached onto the ball run.
