ok i just about had a fly off yesterday , was finishing 45 min duration test , flipped switch to manual mode and added throttle and banked to turn towards myself , i soon lost all control of all surfaces and throttle. i only have rudder going through the controller for nav and channel 5 for mode switch , so whatever happened effected the receiver . it flew off to the east straight and level . panicking i flipped the mode switch back and forth . after about 30 seconds witch seemed like forever , it started working again and i was able to bring it back and land quickly . after going aver everything and considering how the airplane behaved the only conclusion i can come to is the fs8 geeked out and didn't even go into fail safe mode. here is what makes me think that.
#1 "receiver only" controls went out of control
#2 it wasn't a power loss to the receiver because the signal was still getting to the speed controller (it cuts out after 2sec if it losses signal)
#3 it didn't go into fail safe because it didn't do what i programmed it to
#4 after getting it home i found a Strong glitch in channel 4 with motor at full rpm even with AP stuff removed and different servo
#5 ch4 glitch goes away when receiver is replaced with a trusty hitech rx
#6 i went to the fma website and they no longer make them !!!!!!! cant find them any ware!!!!
