Those of us who fly and love the Yak52 have to admit it's a bit of an ergonomic nightmare. The flap lever and undercarriage lever look and feel identical. The undercarriage lever has next to it the flap position indicator lights labelled UP/DOWN. And there are no squat switches or gear unsafe warning system - so Yaks sometimes get landed gear-up, or have the gear retracted when on the ground.
The '52 also has some idiosyncrasies: ASIs in KPH and metric altimeters are common, manifold pressure is shown in mm Hg, while the engine speed is shown in percent RPM rather than actual RPM, following jet convention (military Yak pilots go on to the Delphin jet after the '52).
But none of this matters (except maybe the lack of gear safety features) - it just adds to the character of a very exciting machine.
