I am buying a buggy off a fellow racer and just had one question. It is a Tekno E-converted Losi 1/8 scale. All I need for it is Tx/Rx, LiPo (4s), and a servo. My question is what kind of torque and speed should I be looking for? Can anyone recommend some good budget servos for it? I have experience with 1/8 scales, just not with electronics for them. Any help will be appreciated!
