bout as good as a sfitzer valve works on a real car.

Hell, hell, hell, all of you, me, us!
Now isn't that special?

because idk... i just dont have a car so i cant drive to get any.
so i wanted like would glue or what would keep them together.

how many broken solar cells would work to get about 150mA going into the motor constintly i guess...

i mean the car on a mod runs for about 8mins on a 1500ma
so in a min it has to have 150mA then to go that speed ok its like 173 or something

but how would i tell the mA

also i was thinking i might get a brushless motor and for that it needs 7.2 volts but can go to 12 so i think i want at least 8volts going to the motor with the past also

i mean what if you put it on tin foil and just drew what you needed on the tin foil and put it inside the lines?

but i dont think i can use the epoxy thing though.
so what would i put in it that i should have at home?

If you put it on the foil before you bake, it will bond to the foil. Then you have a rigid mass that you cant get onto the car. Foil is too flexible and you need this precise. That is why you need to bake it directly to the body.

Epoxy is a 2 part glue. Dries hard. You can find it at Home Depot. Use some scrap wood or wax paper or something that you can throw away to mix the 2 parts (equally) and the solars. Then spread over the body and try to get it as even as you can (for weight distribution). Then bake. Pretty easy.

I'll feel kinda bad if he melts his car down to a plastic pile in the oven.

You can by epoxy online if you dont have a way of getting any locally.

And I already posted about how to tell the volts. A multimeter or stick to your tongue. Since it can take between 7 and 12 volts, then you want something with a little more shock than a 9v this time instead of less.

Would I be a heathen if I asked....

Could we see pictures of this when your "done"?

I did tell him to watch it closely.

Also it would just be the shell ontop, so if it does go up in a firey blaze, less weight on the car == longer runtime.

Good that we'll be seeing you in the underworld!

But yeah +1 for pics.

I actually suggest starting a worklog once you get going: http://www.mp3car.com/vbulletin/worklogs/

Take pictures as you go

Sad to say it would probably be the #1 work log and "show off your ride" of the site.

Just pictures of the yellow glob with black flakes in it. People show up and not have a clue why everyone is saying "Great job!" "Cool Ride", "How do you do that fantastic fab work?!", etc.

how do i know exactally how long to keep it in the oven?
and could i let it dry without being in the oven?

where can i get the epoxy again?
hardware store?

Hardware store will have epoxy, but the best quality stuff with the best performance is sold at drug stores. It's a type of epoxy called 'Astroglide' because the performance is so slick. It's very heat sensitive, so you'll want to monitor the chemical reaction with a thermometer. The most sensitive cheap ones are baby ones (because they have such precision fevers).

Also, for the Solars, you might alternately use bananas instead of flowers, especially if you live in an area that doesn't have very many daisies.

When applying epoxy, it's important to wear gloves to protect your skin, so ask your parents to go to the store and get you some astroglide, a bunch of big bananas, a baby thermometer, and rubber gloves.

in the oven, the paste will start to get shiny, this is when the top coat starts to liquify, exactly 30 seconds after that (have a timer ready) it will start to turn hazy. That's when you have to take it out. Don't forget to wear hot-pad gloves, and keep your windows open, the chemicals in the paste can be toxic if not handled right.

Let it cool for at least 30 minutes before you touch it.

The lexan body will need to be completely covered for it to work correctly, any exposed lexan will melt and ruin the entire process. it's got to be at least 1/8th inch thick to properly insulate the lexan too.

The thermometer needs to not be digital too, that will mess with the thermoreactions.

Stop it! This one got me rolling. I'm at work and people are looking at me funny. There is no WAY to explain this to anyone.

He should also pick that particular time to tell his folks "I want a puppy too!"
