this is interesting...
mine is flat and i did a search and see that there are also fin-shaped tail annodes that, if adjusted correctly, seem to be made explicitly for tackeling the 'wander' problem
this guy really explains how it works pretty good:
i think ill get one of those and see if the wander gets reduced a bit.
thanks (mjjwjr and shrew) about the info about the prop.
i think ill leave it in that case. perhaps just give it a bit of anti corrosive spraypaint.
