What does "servo range of at least 300oz" mean

[Mamsurg]

What does 300oz mean when discussing tail servo range?

[Beeg]

That would be the torque of the servo in oz./in. In other words how much power the servo has...

Here is an example for older, non-high voltage (HV) Hitec servos.. Notice the torque listed at 4.8 and 6.0 volts in oz./in.

If you want even more torque in a smaller package go to Hitec, MKS, Spektrum and look at their HV servos.. at 7.4 and 8 volts they start getting pretty powerful..
