Hitec HS-645MG
Torque:
4.8VDC:
 106.93 oz-in. (7.7 kg-cm)
6.0VDC:
 133.31 oz-in. (9.6 kg-cm)
Speed @ 60 Degrees:
4.8VDC:
 0.24 seconds
6.0VDC:
 0.20 seconds
Bearing Type:
Dual Ball Bearing
Case Size:
1.59"x 0.77"x 1.48" (40.6 x 19.8 x 37.8 mm)
Weight: 2.11 oz (60 g)

If you don't care that much about speed, I would recommend a GWS S-06 MG
slightly taller than standard servo
Approx. $20
MG replacement sets are inexpensive for this servo at about $6

XTM High Torque servos are pretty inexpensive on ebay last I checked as
well.

My bad..the 705 is a 1/4 scale servo...
of course with a dremel and some ingenuity I am sure it might work... =)

I'd second that. It's the strongest servo in it's size (from Hitec). No need
to go to the 1/4 scale units.

We run JR Z650 in our Savage and our 1:8th buggy, for the steering.

If you break it, let us know.

I doubt you'll have any problems with it.... IIRC 9.7Kg at 6V....
