I too had a Mirage Kfir and she flew great, not the fastest jet you will see but she flys scale and looks great in the air. My Mirage took every bit of 400 ft of grass runway to rotate. I also had to get all the elevator I could. I believe I had over a inch of travel on the elevator. My nose was pitched up just alittle. when she rotated off for me she took a 45o angle, and kept going it was a beautiful sight. The CG if I remember it was just forward of the retracts. I have the manual some where around I will try to located to get exact.
