Question about the C.G.
My H9 Edge 540 runs the saito 1.80 without any modifications. Believe it or not. I had to add 1 1/2 pounds of weight as far forward as I could (on the motor mount) And still may require more weight. I first flew it without any weight and scarred the hoola out of me... Granted I am knew at the field of aerobatics and 3D but I don't know if I can be off that much... My C.G. is at the spar or just behind the red strip. I heard only one other guy say the same thing and he apparently does not have any problems as well. Any suggestions? Am I really really off? Is this plane supposed to fly like it is tail heavy...
Appreciate any input...
Allendc,
How much elevator throw are you trying to fly with. Low rates should be about 1/2-3/4 inch and no more.
