Magnetic coil spool

This is designed to fit together and form a "mold" to wind enameled copper "magnetic" wire onto. The wire can be glued with PVA glue before and during its removal from the spool. A "Release agent" is probably required. Suggestions include cling film or Vaseline. The coil will be coreless and light weight. Ideal for creating a magnetic actuator for RC planes, cars etc.
Actuator RC receivers are available and I plan to create my own conversion circuit for a standard receiver using a small H bridg
