Mounting position, front or back of the main shaft.
Is there a general consensus about where the FBL unit is to be mounted? IE in front or in back of the main shaft? Or is it just personal preference? Does either one gain advantage?

If you're using a 720 and want to set up one of the bailout features, closest to CG is optimum (under mainshaft if possible). With that exception location does not seem to make a difference on my machines.

Wish it was the 720,
But it is the 540. I was thinking about the gyro plate right behind the main.

We might have to wait for a 540 user to chime in and confirm, but with the 720 (and I am not using bailout, etc) my two 550e's have the unit mounted high behind the main shaft, and there seems to be no differences in flight characteristics compared to my 600n's where the unit is mounted in the front.

You didn't say which heli, but it Doesn't matter either way.. Both will fly fine. I use both configurations. Its only important to tell the FBL unit where its at in the setup. Now with that said, I do like to mount in the front away from the tail/gear box to reduce any vibes.Happay Happay Happay...

Mine is mounted in front and the other 3 pilots that are using it at our club also have them mounted in front.

As to the heli(flying tank,strong)with a MinAir 55 head. I can do the front but it won't be as close to the main as the rear would be.

As long as you mount it as per the directions (90deg to main shaft 90Deg to frame) you'll be fine, only reason I didn't mount it where I had the gyro before is because I wouldn't have access to the usb port and I didn't want to use extensions for the servos.
