Plans indicate the trailing edge beveled edge on the top of the elevator pointing 15 degrees up, causing a permanent down trim.

The instructions indicate in two separate places, the beveled trailing edge should be on the bottom of the elevator creating a flat and  neutral lift trailing edge.

My question is:  which is the correct?

I'd build it with the top flat and the bottom bent. I also called roger and was told to bend the trailing edge after test flying to reduce a nose heavy situation. Many others have as well. The bottom line is you will likely have to bend  it after testing no matter how you build it due to variations in the cg. Its easy to bend actually, just rip a groove in a 2x4 and slide it over the edge and bend it all at once.

I purchased my tail kit in 2005 with the upward-bent trailing edge.  First flight last year she was nose heavy.  A call to Roger at Zenith and he told me to bend the trailing edge down so the top surface was a straight tangent line all the way.  My plane flies great since.

Thanks, Krzysztof!

I just got an updated drawing of the elevator from Zenith.  The new one shows the bend on the bottom skin, with a flat upper surface.  If you can send me your email address, I'll forward what the sent me.  I'm at

Hi, I'm only starting in this game myself. I finished my rudder and coming to the end with my horizontal stabiliser, but two things I've learned so far are: your plans go before any instructions and pictures in instructions are often up side down, a bit confusing.
