Iron Eagle you would be hard pressed to find a higher performance or heavier aircraft since the 30's or so that doesn't have (balance or servo) tabs of some sort, Nearly every WW II aircraft has them. Even the light low perrformance aircraft will have at least a plain trim tab.

Iron eagle and Da Rock,
I was meaning
balance and servo tabs of some sort, but I didn't write it very clearly. I agree with Pimmnz, they are very common right up to modern aircraft including those with hydraulically boosted controls.
Iron Eagle I guess you meant to say the Golden age prior to WW II.
