If there are no balancing specs that come with the manual...meaning how many inches from the leading edge...how do you know if the plane is properly balanced? You could move your fingers up or back eventually until the plane balances but how do I know the exact location?
Thanks,
Pat

FIRST OF ALL ,WHAT KIND OF PLANE DO YOU HAVE? YOU CAN FIND THE BALANCE POINT BY MOVING YOU FINGERS BACK UNTIL SHE BALANCES OUT BUT WHO KNOWS IF THAT IS THE CORRECT BALANCE POINT. I WOULD CALL THE MANUFACTURER OF THE PLANE TO FIND OUT THE RIGHT BALANCE POINT BEFORE FLYNING IT. GARY

For a start try putting the balance point at 33% of the mean aerodynamic chord. That's for taper wings. For straight wings 33% of the chord. I should be slightly nose down, about 3 to 5 degrees. Unless it is a radical free flight design that will work about 98.9% of the time.

This plane is a Kyosho P-40...as far as "33% of the mean aerodynamic chord"...I have no idea of what that means. 33% of the distance from the LE to the TE?

Here's a graphic that should help you determine the Mean Aerodynamic Chord (MAC) and the CG. First point to start is 25% of MAC, then move it back gradually as you get use to flying the plane. It will eventually start to feel unstable, so you move it forward a 1/4" or so from there.

Good luck,
