When I started racing back in 1988, standard servo's had about 40 oz. The best servo you could buy was an airtronics 151 and they didn't even have 130 oz of torque.
At the same time back then we weren't trying to turn big heavy 4x4 trucks running 40mph though. I still have a couple Futuba 148's laying around.....somewhere
130oz. may be just fine for the OP
