You may try a high presure bottle rocket propoltion.
Well I'm pretty skilled in engineering. Once I learn how to do it, I'm good at it.jrrdw wrote: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.
If someone can post a guide or pictures of the internals....
Ok. Here's what I know so far...
-Magnets on both sides of armature
-Armature is an electromagnet
-Axle connected to armature
-Coiled wires around armature
-Brushed transfer power from batteries to motor.
Ok...Can I use neodynium magnets? And where can I find an electromagnet? What's the power mainly based on (batteries, magnets, electromagnet...)?
