Good going.
Which receiver are you planning to use? Does it have actuator support?
If you are using a conventional receiver you may have to use a servo. (2g) An actuator may not be strong enough for an outdoor model.
However, enamelled copper wire can be extracted from electronic inductors or relay's.
For the ESC, you can add a smd mosfet to handle more current.Have a look at the pic below.
