I can only get my gain at about 60 on aileron and elevator before I get a wobble. I replace all my bellcrank to 700e to get the most resolution on my servo. And I even used the jr small servo wheel on the jr8717 servos witch are 10mm from center to ball link. I have my pitch set at 12 degrees, elevator and aileron at 11 degrees. My pitch rate at 51, aileron and elevator rate at 73. And I also do the trim flight but for some reason I always have a drift to right.

Most are running the gains in the 50's on the 700.

Mine are 55 for both AIL/ELV

60 is very high for ailerons. Most end up in the 35-45 range for ailerons. The elevator can be a lot higher. You really need to tune A and E independently.

AJ,
There is absolutely nothing wrong with your gains.

If your able to go that high and not get any wobble then awesome!

For me after 60 it started to feel almost to locked in.

It depends on the configuration and flying style. I have seen it has high 90 and as low 30 and everything in between. In all cases the system worked well which is more important than the number.

When you say a drift to the right, do you mean tail drift or aileron drift ?

aileron drift to the right. So I guess my gains are ok then, thanks a lot for all the input. Thats what im going to do next is to tune my aileron and elevator gains seperate. Also I am using trueblood green head dampeners, is it better for fbl head with stiffer dampeners?

The TB damps might actually be a bit to stiff on the FBL model. On the flybars they rock.
