Ive Flown and love this plane, but had issues with the CG range given by the manufacturer. It states 40-45mm back from the leading edge. Trying to balance this plane in that range would make have to put more than 2oz of weight in the nose. After trying to make this happen I thought that was excesive. I found RC Informer used 2oz in the nose and that plane flew great. So putting the 2oz in the nose the plane balanced out between 50-55mm back. The plane flew great with no trim needed, and have been enjoying this little guy.
Ive also read where another pilot has flown his with out checking the balance and his flew great.SO the question is where is the correct range? how have others set up and flying gone? I know the plane flies great so it doesn't really matter but I'm a stickler for correct set up info

I don't have this model, but a friend does. His flies OK but he doesn't fly it often. He never put any weight in his. Maybe that was the problem.
Manufacturer stated CG in their manuals are merely "suggestions" on where to start. Some are dead on and others are so far off, you wonder what they were thinking at the time. If it flies well with 2oz of lead in the nose, then do it. If it flies well for you without weight, that's the way to do it. As far as this goes, there is no "correct" set up. Just do what works. The "correct" set up is what the manual says, but the manual could be wrong.

G'day jfs,
Just as viper says.
Use the CG nominated by the manufacture as a starting point just as viper said.......why am I typing any more?
Do what viper said!:cool:
Regards and respect

Perhaps you can use data from the full-scale version, and translate them to the model: http://4.bp.blogspot.com/-5jtAGkY0Mv...600/sf_cg1.jpg

Models are very rarely 100% true to scale, and have been altered significantly from their full scale counterparts in order for the RC pilot to have a more enjoyable experience. This alters the way the plane flies, and the point that it balances.

As Viper said however, the recommended CG is a starting point, and every pilot has a preference on how they like their planes to fly. Tail heavy is more responsive, but easier to lose control, while being nose heavy makes the airplane more docile and less responsive. These foam airplanes are, for the vast majority, designed to fly, out of the box, on the recommended battery, with no balancing required. It is a very rare occurrence that I balance a foamy.
