Controlling an ESC

Hi Guys,
So Im working on building a UAV using the Basic Stamp px2 and Propellor. I am having a problem that is so simple yet it's driving me nuts. I cant seem to control the ESC of my airplane with my microcontroller. I have an actual RC airplane transmitter and reciever which I looked at the throttle output with an oscilliscope and it is indeed PWM just like servos, 45-50hz of 1-2ms non-inverted pulses. I emulated said signal with my microcontrollers (it looks almost identical on a scope to the RC reciever) but nothing happens. Anyone have any ideas?
Thanks,

I think but I am not sure that when the ESC is powered up and it doesn't receive a signal within a given time It will not arm. Try if you haven't already sending the signal to the ESC before powering it up.
Edit: Make sure your prop is off.
