Default VIPER TRIM ISSUE:

Hi guys,

Got another one to run by you's.

While trimmed to fly straingt and level I end up with the following trims on the plane.

*** 12 Clicks of Left Aileron
*** 5-6 Clicks of Up Elevator

Now the Plane is a Viper and it is set up with 0-degrees across the board. It pulls a bit to the right and down, therefore the above trim. The lateral balance is OK and I'm at 2-3/4" C.G. When flying the course it seems to turn 1 nice and straight and level and goes where you put it. Why? Why would she pull down? Nose heavey , I don't think so in fact I just moved the CG back from 2-1/2". Down trust, it's at zero but even if there was a 1/2 a deg or so, most planes have a little (oe are all bets of because of the type of plane it is). I would not think it would make that much difference or could it? Rolling to the Right? Engine Torque? I am trying to get it to fly absolutely straight and level with all trims as neutral as possible to loose the drag. Any sugeestions. You guys have been awsome before!

Thanks

Ed
