Ok I know this isn't the best of models but I got it cheap so I ain't complaining plus I got ailevator and flaperon set-up so that should make for some fun.

Question is how far back is the centre of gravity on your one? The manual which I don't even think is for the texan states 3-4" back but in my plane it is sitting about 4.5" back...and I can't really do anything to move it forward as it already weighs 6.5lb....

Forget the instructions and work it out at, 25% to 33% of MAC.
Start at 25%, this will be a little nose heavy however, it will fly ok.
Once your happy the plane flies straight and true start moving your C of G back a little at a time. A great test is to fly a 45 Degree upline, roll inverted. What happens? If your plane continues on the up line with no input correction needed, it is more than likely "Tail Heavy". If, on the other hand your plane falls out very rapidly, it is more than likely "Nose Heavy". What we are looking for is a very gentle falling out... C of G about right.

Hope this helps some
