Hi Curt, FMA Direct FS8 Receiver has serial output which can be used with their Windows software to view the current position of the control outputs. If they provide the protocol (or if it can be reverse engineered), you could simply read the output of the receiver on-board the aircraft and control the actual stick inputs. I'm hoping to acquire one soon for testing. In addition, the receiver also records the amount of interference that is encountered. Could be useful as you try to determine the amount of interference produced by the other antennas on the aircraft. I have a similar setup at work and we have had interference problems as well as a crash or two :-) Two questions on your crash ... 1) Did you do the stall test on the Rascal with or without the equipment? 2) Did you possibly point the R/C transmitter antenna at the aircraft? Pointing the antenna at the aircraft is easy to do when things are going bad and the aircraft is low to the ground.
