Thought of posting the cause of a problem that took me 3 days to overcome.
I have a Futaba Gyro GY401 with S9257 servo. My radio is a JR9303 and i came across this weird problem (For me at least as i am a newbie)
I was trying to setup my gyro to initialize at HH (AVCS) mode. As you already know, it has a light that blinks or stays on or off according to the mode or situation. After i setup the values for normal and hh in the radio, i turn on the gyro/receiver just to get a constantly blinking light. Servo seemed to work fine when i was moving the heli at both modes (normal&rate) but the light was not staying right. (On at HH off at Normal) it was constantly blinking as i said.
As i haven't get my proper battery for the heli (Which is 2250 or 2500mAh 3cell 11,1V 25C) i used a battery that i fly my foamie cessna with, which is a 1800mAh 7,4V 2cell 25C LiPo. And this caused me a three day trouble.
At a fully charged battery (Wrong one though) i was getting correct leds, but it seemed that after a few minutes the voltage was going down, beyond the voltage needed by the gyro and that caused the blinking light (Alarm) though the servo was corresponding correct.
So the conclusion is that you should make all the electronic setup using a proper battery (11,1V) in order not to take wrong indications. The setup will still be able to be done with a lower voltage battery but you run the risk of getting wrong indications and get confused. (Like i did:arggg:)
