I am wondering how to boost the PWM signal from the RX to my servos?

We are going to need more info than that, what exactly are you trying to do?

Im trying to make a Amplifier/Buffer cause I have to Y-harness two servos and know that a little of the signal gets lost when you do that so I want to boost to to make it go through loud and clear lol

No need, you can safely link half a dozen servos to the same RX signal output if you make sure they get enough power. Just use the Y-cable, plank folks do it all the time.

I agree. The signal doesn't need a lot of power to make it through your lines (since it's digital data) and many of the systems they have set up in giant scale machines dwarf just about everything we have in helicopters.

I agree with the the posts above, however I will offer some explanation.. The servo input from the signal line should be a high impedance pin.. This means that very little current flows that you need to be concerned with splitting down a parallel branch.. The voltage on the PWM is merely sensed on the pin at the servo. As stated, you can parallel many servos together without issue as long as each servo is powered from the bus correctly.
