Yep! Note that boards with external oscillators and the typical internal resonator at a normal temperature are not quite the same. The ones with (and using) the external 16MHz oscillator should line up exactly with the numbers in microseconds, but the internal rc oscillator ones will drift quite a bit based on temperature.
I was testing the RCTimer 20A (which is just like the Plush 18A) in my RC Car, and it works well, but as it heats up the internal oscillator drifts and thus shifts the area of the neutral throttle zone, which means I have to keep adjusting trim. It probably makes more sense to use boards with external oscillators in this application.
