RE: Let me get this straight ! [8|]
allancito,
Are you using the FS8 receiver? Despite all its features, it's still a PPM receiver. If you are testing with very strong signals, it would not be unusual to see the effects you observed. When the transmitter is very close to the receiver, the signal can get into the receiver through a number paths other than the antenna. These signals from different paths recombine in the receiver with unpredictable results, sort of like when you get multi-path reception on an FM broadcast receiver.
Try your tests with the transmitter twenty or thirty feet away (antenna retracted) or at a distance representative of the transmitter - receiver separation while flying. The result should be the same as you get with any normal PPM receiver. The FS8 can do things other PPM receivers can't when dealing with bad signals and interference, but it can't do any better than any other PPM receiver when operating normally with a good signal.
