I had one in my 8ight-T. It's an awesome servo with an overkill amount of torque. Compared to the 9100T I really couldn't notice a difference. Since they both have tons of toque at about the same speed. I did have a problem with my 8711 though. It developed alot of play in the gears. JR has been good with warranty so I am sure they will fix or replace it for me. I just through in a HITEC 7955TG well I wait for the 8711 return and will see what I like better. I went with HITEC this time because they have never given me any problems so there was no reason to leave them in the first place. JR has only given me one problem but that is one more then HITEC.

So anyways the 8711 should be an awesome servo for you. Just make sure you set your endpoints. This servo has enough torque to really do some damage if you don`t.
