Is it possible to make a 40mph+ small scale car? Maybe 1:50 to 1:64...Any tips on making this?

I was wondering if I can install a mini fan propelled by a motor on the bottom, so it can go on walls and such. Would a fan that small exhaust enough power for the car to stick to a wall?

I think that if we want the fastest car it can be done by many homemade candy engines ignited together and 4 jiroskopes.

i cant really help you with the motor. it is a hands on skill that takes a lot of time and skill to master. you can buy meterokre motors off the shelf.

Is there a way I can combine motors? I have ALOT of motors. I used to build Zoids. They were missing a billion pieces so I disected them for their motors. Here's how they look like...

Well for your fan idea, Tower Hobbies carries ducted fans for electric fly jets, but the problem there is there pretty big. 3" to probly 5" on average, there are different sizes, depending on motor size and fan size. SpudStuff is rite about the hand winding, it is a mastered art! I rewound a Chevy altanator for kicks, I'LL NEVER DO THAT AGAIN!!! And that is a much bigger easier scale, i think my little copper wire was touching something it wasn't saposed to and up in smoke it went as soon as i started the engine.Any how you can also try ebay for the motor, there's a lot of hobby stuff all the time for sale.
