That is strange. I must admit, I probably haven't done multiple consecutive forward flips in the few flights I've had on my 500, only back flips but I will try if I ever get out to fly with all the bad weather we are having around here.

Didnt read all your posts as i;m in hurry but is your gain against black background or white, i had my 7hv work one way but not the other when gain was gainst white (should be against black)
Another thing to try is to recalibrate the sensors
Can also be blades or swash not level throughout range

Thanks for the pointers!

Yes, gain against black
Sensor recalibrated
Blades are 3G blades, balanced, but will try another set
Will check swash again

ok guys, just noticed this today, I have now mounted the unit on the side frame & changed the units orientation under sensor menu. The first thing that got me was that after changing the orientation I had to reverse each axis sensor direction, I've done the same with the Mbeast & just changing orientation was all I had to do, everything else worked as normal.
Next, now that every axis is working correctly including the tail every time I give elev or ail input the tail slowly moves to the right (if you stand behind the Heli). This I've never noticed before, this is with the Heli on the bench, has anyone noticed this?

That's cyclic DMA, same as when you go from mid stick up or down on collective tail should compensate, normally to give right nose thrust.
the higher the value the more the throw, strange that you had to change sensor direction, did you also change wire orientation?

I was thinking the same about servo plug order but even the tail sensing I had to change.

Does anybody know what pulse rate and frequency to use with Hitec 225's on the cyclic?

You can check on Beastx web site, they have a pretty big chart with a lot of servos. Maybe yours are there

I have already been to the beastx site and my servos are not in the list.

Do NOT use 760Ás.

You are mixing frequency in hz (the number of times per seconds the servo gets updated with a command from the FBL unit) and PWM (the Pulse width Modulation, in s, that defines what the center reference for the servo is). So for your analogs on cyclic set them for 1500 (or 1520, can't remember) Ás and lowest frequency (70hz or so, can't remember either)

Your tail servo is digital, I would set high frequency (333hz) and it is most probably a 1520 Ás center as well.

I was under the impression that 760us was for analog servos and 1520us was for digital.

Wrong, again, you are refering to the centering PWM of a servo. Most servos (analog or digital) center at 1520 Ás. a few at 760 (Futaba BLS251, some MKS and others...)
Set you analog to 760Ás and you will most likely fry it


Drive frequency 65 or 70 hz is for analog, above for digital.
Likewise, set your analog to 200 hz and it won't be long before you see some magic smoke out of it

How do I set the pulse rate for the cyclic servos? I have only seen it for the tail servo. Unless the cyclic pulse rate is non-adjustable.

I am a noob to setting up FBL so patience with me would be appreciated.

My answer was general. Most (all) units do not allow cyclic servo pulse rate adjustment because most servos used for cyclic are 1520Ás anyway.

So for you.

Cyclic:

set lowest frequency (analog)

Tail:
set high frequency
set 1520 Ás
