It works fine on PCM. Just if used with PPM it detects interference and moves the servos to a predefined point just as PCM lock out does. If used with a PCM receiver this feature is not present since the receiver detects interference and continuously sends a valid throttle servo signal. It will drive the servos with a 40Hz PWM signal even if used with a radio with a faster frame rate. It can accept any incoming frame rate as long as the PWM is .5 - 2.5us per pulse (all radios on the market are 1-2us +/- 20% that I know of including high frame rate digital systems).

I will do another prototype build definitely that will result in my having either (3) or (6) more of them. One of my local club members wants to do some testing with it. I want to get a few more people testing them. So let me know if you are interested in being a beta tester. Beta testing should start in a couple of weeks. Production is a couple of months away if I decide to do this. If I do production I would be open to taking pre-production orders at a very low price to help with the initial production costs.
