has anyone modded say http://www.hitecrcd.com/products/servos/analog/giant-scale/hs-805bb.html or any other large scale servo on the savage. i was thinking of spending arround $40 on this servo rather than $120 on a regular size servo with the same torque. i just wanted to know if people have done this, but i do not want to know how to do it. any help would be nice.
