Actually, the difference between the top and bottom is so slight, less than 1/2 deg, that I'm sure it falls within my measuring tolerance. I'm just putting the meter part of a digital pitch gauge against the bottoms of the wing panels, and it's really hard to get it to even sit still, as I'm pressing it up.

When I built my DR-1, the plans said to set the top wing about a degree more than the other two. I ignored that. I suppose it might be good on a full size, but on a model, I don't want any pitch changes that I don't initiate. There's enough goofy stuff happening with these things as it is without adding to it. Besides, like someone else said earlier, the key to landing these crates is to keep the power on a little and fly them right down onto the wheels. Getting the nose high at all means the wings will blanket the tail and that means big trouble.
