I just finished setting up my 600N on the bench. The BLS451 cyclic servos were butter smooth before I installed the FBL unit. Now they act like Align DS610 servos where they are all notchy and seem like they have lost all resolution. Anyone else notice their cyclic servos went from ultra smooth to notchy after installing the Align 3G unit?

The 500 ESP 3G install requires you to move the balls in on the cyclic servo horns quite a bit. Maybe same for 600? Are you sure you have the balls on your cyclic servos the specified distance from center?

Yes- Align gives you new cyclic horns for Futaba servos. I did use the holes for the balls they call out for which are closer to the center. If I had to guess, it may be partly due to the decrease in swash pitch AFR. I was at 60% and now at 38% to get +-13.5 degrees of collective which is what I usually run. Undoubtedly resolution will be lost.

Very interesting. I noticed the same thing after my 3G install. My normal swash mix for collective on the 500 would be 40% on my 10CHG. It is down to 28% on the 3G equipped 500. I also feel this setup lost some resolution over my flybar'd 500. Everything including collective is now quite a bit more sensitive and collective is not running on any gyro... I had to up cyclic expo from 30 to 45 to have the same feel around center...

i have so far only used v bar but there u can c what procentage u ha to b in to get the right resolution. but it is very important to get it right to make it fly good.but i guess move them in until u get the the correct head room for the fbl unit to work with 50% if possible?

38% sound very low to me. is it not stated in the manual what distance it should b?

i started with nothing and still got most of it left

You can't move the servo ball in any further on the 500 3G install. The balls are on the inside of the horn on a 500 and they would hit the servo body before they could produce the required combined pitch range. I'm of the opinion that the FBL head supplied with the 500 3G kit doesn't have the right mixing ratio. This head should have adjustable washout arms...Thinking of trying the I2 500 head...

I fly a 700 with the 3G setup and did see a noticeable change in my ARF as well. I also see the same bobbling that most everyone else is seeing and beleieve that moving the servo horn ball locations in farther then Align recommends may be a fix for both issues. I will be drilling some horns tonight and experimenting with a distance of 10mm from center as opposed to the factory spec of 12mm to see if increased resolution helps out.
