RE: FMA Co-pilot
Kojak41,
I have never used the Co-Pilot feature, but I have several FMA FS8 receivers. They all work very well and the information that one may gain from the annunciator system is very helpful. Pay attention to what the annunciator is telling you. It does not seem to lie.
One of the receivers required post-incident (my fault) inspection. Their service seems to be very competent and not at all expensive.
I have used both Futaba and HiTec servos with my receivers with no trouble. They have been used with Futaba Tx's. No troubles.
PS: I had a little trouble with range-checking in my first gas-powered plane with an FS8. It turned out that the ignition module was leaking RF. Once that was tracked down the receiver range-checks perfectly.
