When I did my tailwheel conversion training, during my last session we practiced bad wx circuits, and because the RWY was veeery long for the L-18C, the instructor set some parameters:
Max 500ft AGL, base leg abeam the tarmac undershoot, and crosswind/downwind inside the taxiway in the dispersal area south of the runway, as seen here:
MAP- ENDU
Hard? Heck no, just a great way to no get "long runway complacent" in an aircraft with nimble handling
It was nice to get a lot of strict circuits in, because all the short fields we used off base for the L-18C required very non-standard circuits due to terrain and angry neighbors.
