just relized the botom of your post mr, ,

its a gas truck,, no motor, i plan to run this same deal off the throttle servo,, if its pos, ( or giving the carb gass) no brake lights, the same servo also runs a ceramic brake disc and caliper,, so if its negitive the brake is engaged,,, and jualla brake ights come on, my ocncerns for ma rating,, was drawing a splice off two of the three servo wires coming from the reciever box, i think im corect in saying a simple resistor on the input line should cause no more curent then needed to go hi or low will be taken off the servo line enabling the servo to still work with a minute amount of its current drawn off to actualize the signals,, both the reciever and all servos and ic board will be run off a nicad pack,, so i assume the physics of this will alow the signal to be read off the pic,,
as i said i built it and tested operation with out cuting into the actual servo,, wasnt wiling to pay 50 bucks for a bs2 to prouduce it, so i waited to test till i build the prototype for this model, my dad a seasond electronics major said my therories work, so i wasnt to woried about testing it b 4 proceding, at worst ,, ill build a reciever around it and negate the one in the car :P
