Here's the first thing I've done. I've taken the top part cover part of my Scorpion R.C. car. I then used Erector pieces to make a chassis and put some armor on it using a hard, scored plastic. I put a wedge on the front to complete my first competitve design. It's not a Battlebot, but it sure acts like one. It only weighs 10 pounds, anyway. I then added a really cool feature to it. I took a drill motor and more Erector pieces and made a slanted spinner on it. I run it on 6 volts and it spin at an estimate os 3000 rpms in about 5 seconds. Here's more details on it.

Here's the spinner that attaches to the back of the R.C car. The thing's about 17 inches long. more weight needs to be added...I have a cool design feature on it, though. It's made just out of Erector pieces with lots of power, too.

Here's one of the tips of the spinner. as you can see, I use a bar secured rather than nuts and bolts used for the ends, so it spins like a flail. This is so the spinner won't bend after a hit and break. It hits hard but glances back after a hit, not breaking the blade. Using 6 volts (4 "D" batteries), the thing takes a few seconds to spin but it gets up fast to about 3000 rpms. But if you use 9.6 volts from a regular R.C. car battery...heh heh...it spins up to around 6000 rpms in about 2 secounds! That's got power to it.

Here's the blade while it's spinning. Unfortunatelly, the camera I used pauses anything moving, but you can see the tips are swung out.

If you are familiar with The Mauler or Greenspan (both are Battlebots), you will know where I got the idea!

Here's the motor I use for it. It's just your basic cordless drill motor, securely tightened in a slant on the back. The slant just barely keeps the spinner from hitting the ground. I'm proud of the new motor mount I got for it, since the motor won't move around.

Here's a empty cardboard chicken nugget box I beat up with the spinner for about 20 seconds. The spinner's sharp edges has easily put 3 inch gashes in cardboard and has taken good chips out of wood. It even shattered a small plastic box. My goal is to get it to pierce through lexan, which will be a while yet. My friend says he'll bow to me if that is done.

As you can see, it's a real pushover using it's wedge, speed and power. It's got enough power to push my 90-pound friend on a skateboard while sitting down. Using two gears and a top speed of 19 mph, the drive on it was surprising to me.

It's even surprising to my dog, who is afraid of it...heh heh...she knows when to run and hide...

Here's the new interchangeable spinner on it. It's a vertical spinner with the blades made of the same material as the armor, which was all I had. I use the other drill motor I had which has a gear on it. I add a piece of armor on the back to make the car longer and to hold the motor snug underneath the armor, powered with the same batteries. I use a rubbered band as the belt, which doesn't hold out well. I have to see what I can do...
