Guys,
When I went out to do a little practice with my Belt CP v2 last night (the clouds had parted, the wind had died, and the sun was out for maybe 20 minutes), I started up like normal: TX on, plugged in battery to ESC, waited while gyro initialized (steady fast flashing to solid red), then proceeded to spin up and work on my hovering...
After a few up and down hops (not sure EXACTLY how many, but only after a few), I noticed that the LED on my gyro was flashing again. Not as fast as when it is initializing, but more like a heart beat (blink, blink, pause - blink, blink, pause).
I don't see anything in my Belt CP v2 users manual about this flashing pattern, so if anyone knows what this means, please enighten me...
BTW - since I am having other tail rotor / Head Locking issues, I did not see any difference in performance. But then again I cannot get the head to lock correctly either (getting a slow rotation counter-clockwise).
However, I may have found my problem in regards to my overall tail servo setup problem, but want to run it by you all...

- When it is in 1 the gyro is working in rate mode. So try to fly your heli in rate mode. If nose still yaws, lose 2 screws that holds tail servo mount to the boom and move it a little bit to right. If nose yaws even more, move it to the left. And move servo mount till nose stops yawing
When I rebuilt my tail boom assembly, I set my TX to rudder-center, with center trim and the servo at 90deg. I then moved the servo to get 0 pitch on the tail rotor blades (90deg means no pitch, right?
).
I am NOW understanding that this is wrong... I mean REALLY wrong.
And most of all I can understand WHY it is wrong... At servo 90deg, the tail blade pitch should be adjusted to counteract the main rotor rotation naturally. OK - Got it! Now to test it tonight (praying for good weather...).
And another question about the 704B gyro, its POTs and the gain knob on the TX...
I read through another older thread where I think it was FD, P3TRAS, and maybe Nuttzy were 'discussing' the different 'options' offered from the different configurations of gyro settings. Let me know if this sounds right:
TX Gyro switch to 0 = Head Hold mode
TX Gyro switch to 1 = Rate Mode
TX Gain knob at full (-) = Gyro off (?)
The last one I am not sure about, and it sounds like is a matter of conjecture. Does turning the gain knob all the way down turn the gyro OFF? Or set it into RATE? All I know is that the LED turns off when gain is all the way down. I'm not so sure that it is THAT important to me right now, but was just wondering...
Thanks as always for your help!
