How to build a car to epically fail?

Postby BondUniverse » Fri Feb 17, 2017 9:37 am

There's a TON of info out there about how to build the fastest car, but I want build a car that is purpose built to fail!

A little background...

I've just started to help out a cubscout pack that is largely special needs. The Cubmaster has someone that builds her a car that is purpose built to fall apart before ever getting near the finish line (guaranteeing the scout that challenges her will win). This helps with self esteem building for these scouts, which is something that special needs kids need.

I always love a challenge and thinking outside of the box. I would love to create a car that not only fails, but fails in a way that will be fun and entertaining to the scouts. Looking for ideas - surprisingly, I've been coming up empty handed in my Google searches. I've thought about making a car that will "explode" partway down the track, but not sure how to make it function (oh, while I want it to look somewhat legit, it won't be part of the official race, so it doesn't have to meet the normal requirements). I'm open to other ideas as well.

Any thought? Ideas? Examples that maybe someone has done before?

I have a car almost the size of a Pinewood Derby car and it is decorated with "McDonald" stickers that came with the model. Because of the small size, one unit, of the Losi Mini-T receiver/speed control, I was able to make the McDonald's model radio controlled. Now you don't have to worry about it beating someone. Just run down the track half way and then stop it and back it up, even backing it up the hill if you like. The rear tires are of a rubber that the slot cars use. In fact the whole thing is nothing but a radio controlled slot car. CAUTION !!! You don't want to be running "Wide Open" when you run out of track or you're going to get your "Exploding Car".

There are cars on the Derbytalk search function that were built to finish last. That's some interesting reading.

This sound like a car that's right up my alley! I Have all kinds of thoughts rolling around in my head for this car now!

One is to cut the axle in half in side the wheel bore so the wheels could drive off the axles!
Glue the axle head part to the wheel so it looks like it's being held on.

Maybe use a mouse trap to make the car body explode like the old out house toys did when you opened the door.

I think you have the right idea here for a hole lot of fun BondUniverse!

And Welcome!
Whoda.

I actually have one of those mousetrap outhouses! Also had a thought of trying to do some sort of magnetic trigger (sticking a magnet under the track, but not sure how to do that). I also just realized that I have a roughly matchbox sized RC car somewhere too...

I built a car once for our leader. I took a large washer that just fit inside the rear wheels. I cut the washer in half with a hacksaw, then glued a half washer into each of the rear wheels. Other than that the car was normal. When it went down the track, it would go "Whoop, whoop, whoop ..." as the rear wheels spun. It always made it to the finish line, but could not get up enough speed to beat anyone.

Don't know myself on that one!

Could a timer of some sort be set to explode the car body at about half track!
kinda like the old board games ... Perfection or don't wake Daddy ... the trick would be setting it to go off at 1 sec or so after the gate drops though.
Just throwing some thoughts out here.

How about a simple propeller car but run the motor in reverse. It would probably go down the hill but at some point it would stop and try to back up the hill. I doubt it would be able to make it to the top. That should make everyone laugh.
What kind of track do you have? What's the clearance on your timer?

Pretty cool. Though, it looks like it is designed to fall apart upon impact with something. The challenge would be to make something fall apart while still going down the track.

Yeah your right!
However when the car sets on the track it's facing down hill.. maybe with a some re-work to the design here .
A ball bearing track could be made to let the ball bearing roll back while coming out of the curve in the flat of the track to snap the trap ?
Might not snap the trap off at half track .. but i bet by the time all the parts fly off it will end up half track or more.

I built an electric car for an Outlaw class last year that I inadvertently wired in reverse. It went down the incline then back up. You're right Speedster, everyone will laugh.

I wonder if you could make a multi piece car body that would trip like these things and literally explode!
