Elevator Model III Flat?

Working on a Model III and find the elevator fins are not on the same plane. When laid on a flat bench, one trailing edge is about 1" off of the table (fins have diferent angles of attack).

My thought is that there should not be a difference between the two. Is this intentional for some reason? I know of one other with the same deviation. I also looked at a Model IV where there were in the same plane.

Anyone run across this before? I plan on straightening these to be on the same plane unless there is a reason they should not be.

My model 1 is flat I think the only difference between yours and mine is that yours should be 1 inch longer on the cord than mine is

The manual for my Model IV says that it is to help the control surface to be "self centering". Not sure if it helps, but I left mine as built...

This exists in both of my model IVs (1050 & 1200). When I rebuilt the elevator in my Mangy Fox project plane, I left the offset as was from the factory.

DENNEY AIRCRAFT manual dated 24 SEPT.91 Sub SEC. E-ELEVATOR Page F-E-1 Reads as follows NOTE: When you inspect your FE-70 Elevator weldment you may notice that the trailing edge on one side is about 1/2" higher than the other side. It is built this way so there will always be an air load on the elevator and it will not be blanked out by the horizontal stabilizer. DO NOT "STRAIGHTEN" THE WELDMENT!

Excellent info, thanks.

thats great I would like to see a picture of that.

thanks for the info . glad that during my tail project last winter i didn't waste my time correcting that on my elevators . i was aware of the offset between the two but couldn't believe they would allow their jigs to be that far off .

Can't hardly see the offset without the straight edges.
