Basically i want to turn 6 volts and very little amperage into a large wattage to turn a motor in the 20-30,000 rpm range. for a model airplane if that helps. want to make a small can motor turn a prop at tens of thousands of revolutions. maybe a MOSFET? does not need to be fully proportional. maybe just an off-low-high settings. i have seen projects involving an old futaba servo and 500 ohms resistance and 2 or 3 mosfets. PLease HElp.
