I remember the old days well, when a servo under an ounce was considered very light.
And then when 1/2 ounce servos showed up they cost $50 (or more!) each.
Bill Cannons radios were the only game in town for .020 multi channel proportional planes.
Anything that was anywhere near that light back in the old days was only single channel.
Yup, we have it good!
