b.s.



your pcb would frie unles you hooked it up to like a 2 inch in diameter engine and the weight would over power the steering and accel

letalone youd **** up your axels

um..no B.S?
 

Actually, there are threads on this board a million years old regarding how much voltage you can shove though a ZIP PCB. You can go over 9 volts, it's been done, it's been tested, it's been proven to work, so accept it and move on folks.

ok then i tried it though and now my zip smells like burnt curcitry


i sorta beleive you but get me a pic and a tape of it runn for more than a minute then i will belive fully

oh that Zip has long since been recycled...it was just plain rediculous with that big ol' 9v sitting on top. I know there are multiple threads on here that were huge when Zips were first released. People put them through all sorts of tests, just for the sake of research. I think that dude Stridex was the one that used to smoke 1/10 scales with his 9volt Zip. Sorry, no pics or vids here, just have faith brother!

I find this hard to believe. I hooked up the original NOS motor to a 9v battery and it fried it in a few seconds. What kind of motor are you using and how did you bypass the PCB?

could you run a 9 volt through the pcb

You can't run 9VDC through the PCB. No way, no how. You could bypass the PCB with a switching transistor as was done in the 4.5VDC dragster mod. Even if you did manage this, 9VDC will fry any micro motor it runs . The motors are rated at 1.2VDC, you can up this to around 5VDC. Any more than that and you will fry the motor. These are facts, no way around them. I don't see a huge 1/10 scale motor fitting on the back of a Zip either. All you would get is your front end in the air. And a 9v battery strapped on one side would not be stable at all. Not at any speed. Imagine the size and weight of that. It's bigger than the chassis! And, I'm having a hard time seeing a Zip raised 1 inch. How did you pull that off? I don't think any of this is true. Sorry, but this goes way beyond the realm of believability.

And a BIG DITTO to what Azimov posted...

Yeah, you're right. Everybody that's already done it like a year ago is lying just because they wanna sound cool. That's ok guys, you just keep thinking that it's impossible. Keep telling yourself it can't be done. Don't even bother trying, it won't work anyway. *sigh*

if someone could jsut post a SINGLE little image or movie clip of it moving i would be satisfied.

MAYBE A FACT

BASED ON WHAT?

You just can't make up numbers and declare them facts.

I think what you guys are missing is that a Zip motor without any resistance what-so-ever will probably fry on 9volts. It's the RPM's that hurt it, not the voltage. Anyway, a Zip motor in a car has the friction of the gears and the tires, all under the weight of the battery...so in reality it will never get a chance to reach the insane RPM's that it would out of the car. As for the PCB, it can handle 9volts. What it can't handle is lots of current. A 9volt battery doesn't produce enough current to cook the board. Starting to make any sense?

No, I got the point just fine. What you are missing is the facts of inductive loads. A motor actually pulls much more current under stall conditions than it does running freely. It isn't the speed of the motor it is the voltage levels. The small contacts inside can't handle it. They burn like a fuse. As to the PCB. Go get your best car. Hook a 9VDC battery to the PCB and tell me what happens. A 9VDC battery will fry the transisters. They aren't rated to take that switching voltage. If you saw someone claiming to do this, they were mistaken. Just hook that baby up, and see what starts to make sense to you. And none of this supports the wild mechanical claims made of putting a huge motor in the back and an equally huge and heavy battery strapped to the side. Nope, sorry, if this car exists, it doesn'r work, the PCB is toast, and it's lying on it's side.

I don't.

You actually have no idea what the max voltage one of these motors can take. You're guessing because you don't think they can run on 9volts. Your guesses are NOT factual information.

As for making a car run with 9 volts, I did...last year when these cars first came out. So did a lot of other folks. Like I said before, just go on believing it's impossible. As is usually the case, only the people that have done it will know for certain.
