OK,
First let me explain what all that junk is doing on the board.

The power analyzer reads volts, amps watts and watt/hrs. Thats more than enough to tell me whats going on and whats about to burn up if it happens.

The blue LED voltmeter tells me what voltage the receiver is getting. In this case I have a FROMECO pack direct to the Power Expander with NO REGULATORS. Yes the board is 8 volt compatible but it has an onboard regulator so the receiver sees a very clean and constant 5 volts. I will explain why 5 volts is critical later on in this series.

The servos on the right are some new units I imported from China. They are 200 oz at 6 volts and around 250 oz at 8 volts. Lets use the law of averages and assume they are good for 220 oz then. These servos cost $12:00. Yes true and I hope to test them to failure to see if they are any good at all. They are metal gear, seem to function OK and I have 20 to play with and let you guys know what I find.

The four servos on the left are some good old FMA servos from my trainer days and are just to show me if something is moving when it should not. The ganged servos are on rudder, the others are simulating throttle ailerons and elevators.

Simple stuff I hope.
