I spent an hour slapping this together and having some fun with preliminary tests. I was able to fly my Blade mSR and Phoenix Flight Sim models using an untethered A9.

Overall it was pretty cool but it was glitchy enough that I won't try it on my mCPX just yet. The mSR was losing the link periodically and Phoenix was glitching collective on my heli models; I could see the red LED flicker once in a while as well. Controller had to be recalibrated under Phoenix as the pulse lengths were quite far out from the direct wired PPM that my A9 is providing.

I should also mention that I was powering the receiver with an old ultra-micro (E-Flite 1S120/15C) pack and the PPM line from the board was hard wired to the TRS connector -- no level converters, buffers, pullups, or current limit resistors were used.

Thanks for the amusement Si, it's nice to have odd projects like this to tinker.

[update: NiMH receiver pack didn't cure the glitching]
