We are talking 12Volts, (4 Volts down on the standard 16V) even on the C7030 you could get down to below 11V before the brownout would cut in... Actually I think I shorted out one of the diodes so that would be + 0.7V so actually only down 3.3V.
3F is the hexadecimal value that the computer chip inside the 4PB reads when the throttle is fully pulled. Except for a lot of the ealy ones it didnt get anywhere near. Adding a resistor in parallel to the main slider would reduce the max value (throttles go from zero trigger=zero ohms to max trigger=max ohms) so it would reduce top speed.
