I had this same thing happen to me with the same symptoms as you just described and it ended up being my radio going into fail safe due to a malfunctioning battery, check all your batteries and connections and do a good range test on the ground before you fly again just my 2 cents
same here. same exact problem as you are describing in the first post. it's not so much a loss of signal type of failsafe, it's a low voltage at the receiver failsafe and it cuts throttle to let you know you have a problem. A123 1100mah packs are prone to losing capacity with no warning. they're good one flight, bad the next. check the carb all you want but also check the capacity of your onboard flight batteries.
