I remember Rex talking about this with me too....I agreed with him, and
that's how I set up my models (hi wing). The planes with the wings at
zero, like the Lacey, fly with the fuse at an angle with relation to
the direction of flight. Depends what you like. IMO I like the fuse
parallel to the direction of flight, less drag, less angle between the
rubber and prop shaft..... Now hi wingers need down thust anyway so I
put the wing at 2 or 3 and stab at 0, the effect, like Rex mentions is
2 or 3 down thrust.
With low wingers having the stab at zero sometimes means having too
much down thrust built in, so like some folks, we split the
difference.... 1 or 2 in the wing the rest in the stab. ie wing at +1,
stab at -1. Low wingers with the gear down or on floats have even
higher drag down below and a pitch down moment with power, I've had to
add up thrust to some ROW models (and up thrust just looks plain weird
in a model)....they would fly nicely under low power but dive in :) at
hi power....so it is a balancing act between full power, flying
attitude and wanting to keep the thrust line as straight as possible.
My 2 cents
