Default Servo Equivalents

Can someone advise me the Sbus equivalents in terms of performance and physical size of JR 8411 and 8711?

Thanks
Malcolm

Pardon my ignorance as I know nothing about S-bus. At present I fly with a fair range of different servo makes which are mainly digital, but some are analog. If I was to go totally Futaba and S-bus, would I have to replace all my existing servos with S-bus compatible servos?

I'm using Align Servos for my planes, I used this for my helicopter and they works hard and so far today I haven't had any problem.

Align DS-610
Torque: 4.8V:133.3 oz-in (9.60 kg-cm)
6.0V:166.6 oz-in (12.00 kg-cm)

Speed: 4.8V:0.10 sec/60°
6.0V:0.08 sec/60°

Nice and cheap.
US$67.99

I did some googling:

http://www.futaba-rc.com/sbus/index.html

Not only can you use existing conventional servos operated via a number of SBD-1 S.Bus Decoders, but you can also convert any make of Rx to S.Bus, not only Futaba, by installing a SBE-1 S.Bus PWM Adapter.

I guess most of you on this thread already knew that, but it gives me, a long term JR and Spekky user, food for thought.
