A number of Bf-109 pilots would have the slats bolted into the retracted position to keep a asymetrical slat deployment from ruining a gun attack. ..this was a designed in feature, Luftwaffe rationale was help the pilot spray his fire. As survivors built aiming skills, they developed a

extended position. Part of the walk-around is to push up on the slats and note free and easy movement. Air pressure against the wing moves them to the retracted position. As airpseed is increased/reduced they extend or retract in response to the corresponding force of the relative wind.

that is simple and effective. I've always thought it would be kind of fun to impliment something like this on an R/C model, not that the typical R/C model would need them ... I once saw an F-4 with controllable slats - they weren't automagic though. The Bf-109 and Me-110 has aerodynamic

Just finished adding quite a bit of detail to the a-4c attitude indicator. A few things to bring up: 1) The flags. There are four of them in the photos I've seen but so far I haven't found any information on which is which. One has the word Off on it, and I assume that it means the entire
