Can the HS7985MG servo use for the 1/8 buggy steering?
Enough torque?

More than enough torque for buggy or truggy. I run a 140oz torque servo on steering in my buggy, no need for more.

Ok! thanks

The 7985MG should be enough in the torque department, but for the ultimate in protection against stripped gears our titanium line can't be beat. You can find more on our servos at: www.hitecrcd.com
