Just went through all Futaba hv servos at towerhobbies (
http://www3.towerhobbies.com/cgi-bin/wti0093p?&C=MAL) on weight attribute.
Was not able to see one in mini-servo category that is suitable for elevators.
Personally I would prefer to use hv servos in a pattern plane.
The S9070SB looks perfect for elevators on paper. It has the same features as the BLS171HV. I like the package where the mounting lugs are high on the case so the output arm is not too far above the bearings. I like the way the cable exits the bottom of the case so it is easy to install the servo in a perfectly sized hole. However, I do not recommend the S9070SB. I'd like to hear from someone else who has tried them.
