:ö: squeegee,
The 5.4gram is the exact weight of the servo, which is important if you are building an rc plane, wherein weight is one of the factor to consider if you want your model plane to fly properly, but if you are building a 1/87 rc truck, weight is just an option and size does really matters the most, next to consider is the torque or the mechanical output of a servo, but speaking of torque, micro servo such as the 5.4grams servo has more than enough torque to turn even a 15mm or bigger diameter off-road tire
