hamfist

So you could make an altitude flight and probably never touch the stick. But this does not lend itself to some of the experiments that we had to accomplish, and the system was an experimental system. It was not required to go through these whole modes for the flight. In fact it is sometimes easier to do it yourself rather than rely on the automatic system, because you know where you are and you know what you are going to do. Sometimes you forget to turn one of these whole modes off and it might get you into a bigger problem than if you were hamfisting it around yourself.

1968, W. J. P. Knight, “X-15 Performance and Piloting Tasks”, in The Aeronautical Journal, volume 72, London: Royal Aeronautical Society, →ISSN, →OCLC, page 801, column 2:

Normal A-7 departure procedures also call for disengaging all modes except yaw stab of the AFCS. Since I was unsure of the problem and felt it may have been AFCS-induced, I luckily decided not to reengage any higher modes. The position of the culprit nut would probably have been aggravated by using control augmentation or “hamfisting” the stick.

1981 March, Bruce P. Eaton, “Expect the unexpected”, in Dale E. Smith, editor, Approach: The Naval Aviation Safety Review, volume 26, number 9, Norfolk, Va.: Naval Safety Center; Washington, D.C.: U.S. Government Printing Office, →OCLC, page 32, column 2:

The Aerobat is really a pussycat in tiger stripes. It has never claimed any aerobatic fame, and is basically just a beefed-up 150/152. I tried to abuse it—by botching an imaginary base-to-final turn or by hamfisting a steep turn—but I could not goad it into biting; that’s probably a good trait in a pilot’s first aerobatic airplane.

1981 May, Nigel Moll, “Over Easy: Straighten out and fly right is the wrong advice for the pilot learning aerobatics”, in Richard L[awrence] Collins, editor, Flying, volume 108, number 5, New York, N.Y.: Ziff-Davis Publishing Company, →ISSN, →OCLC, pages 98–100:

The plastic tube holding the tail-rotor wire has a hard time passing through the black support in the tail boom. Enlarge the hole with a needle file to avoid “hamfisting” and kinking the tail-rotor rod.

As I said before, I’m new to gliding. Still have a bad case of “hamfisting” the 1-26. In fact, if it were transponder equipped, I’d squawk “7700” entering downwind for every arrival.

1995, David R. Haag, “Soaring Mail”, in Soaring, volume 59, Hobbs, N.M.: Soaring Society of America, →ISSN, →OCLC, page 2, column 3:

It is also quite frequent, for beginner pilots especially, to become excited in the firing instance and further scatter their fire through hamfisting of the stick.
