There have been a lot of arguments on this issue. The airplanes I have
had trouble with were usually toed-in, or had uneven alignment (one
wheel toed-out, one straight). Cessna and American Champion, among
other manufacturers, will ask for zero toe-in or out.
The RC modeler crowd seem to favor the toe-in outside wheel
scuffing drag theory, but they're operating mostly off grass and have
no idea how an airplane "feels" with toe-in or out. They spend most of
their early hours groundlooping no matter what the alignment. The RC
flying I have done just tells me that it's a lot harder than sitting in
the real thing and flying it.
The toe-in, seems to me, would be counterproductive anyway,
since the inside wheel in a groundloop has little or no weight on it,
and the outside wheel will have more say as to where the nose is going.
I would align the wheels straight as best as I can, and tolerate a tiny bit
of toe-out, if anything.
