Well I have to say that I've discovered a new piece of bait for the forums if I'm having a dull day and it's to post a statement in a pattern forum that a 0-0-0 setup flys straight :-)

Thanks Tony0707, and don't take the comments to heart too much, pattern flyers are very glass-half-empty folk when it comes to how straight and neutral a plane flys and strive for perfection in nearly every conceivable orientation and loading even though deep down we know it's an impossible dream.

I'm off to a 4x4 forum now to ask if I should fit a diff locker to the front or the rear.... :-)
