I have had a lot of problems locating a decent schematic for a speed controler
for a cordless drill.
  
The type of schematics I am looking for is one that:
 
       1. DOESN'T use a transitor/resistor design (i.e. heat/excessive drain).
       2. doesnt require extremely hard to find components.
       3. can handle around 1amp at 6volts.
       4. will hopefully have some torque at lower speeds. 
 
I would appreciate any help through e-mail or through this newsgroup.
