I want to go back and get the weights right in the tail/rudder/etc. I think if I got those weights close the plane would mimick the Knife even better. Thanks for the compliment. I have a Bucker Jungman that I have made for Real Flight that does fly just like a Bucker. I also have tweaked an Ultimate. I you want to 3d, learn how to hover, learn how to torque roll and even flat spin inverted or upright (not an easy thing to coax out of a Real Flight plane) this is the plane. I have downloaded all of the "3d" models and none of them come close. I'm getting pretty good with tail touches on this one. The only problem is I don't know if I'll ever be able to afford a real plane that flies like this one. If I could I'd be on the circuit!
