Default RE: VIPER TRIM ISSUE:

Ed, you may want to see if, like Scott C. said, that clears up by moving the CG back to the rear just a bit. With the fuel tank in the nose of the Viper, the fuel load moves the CG forward causing you will have to trim the elevator up some. I bet when you are near the end of the fuel load, it wants to climb just a bit as the CG moves to the rear some. 2 3/4" ~ 2 7/8" from the LE of the wing with the fuel tank empty would most likely take some of the up elevator trim out.
