I have been flying the F-15 the past few nights with no problem at all. Taxi is a breeze, so is take off and landing. The plane is actually easy to fly, and I think very forgiving. Landing is the easiest part for me, very smooth. If you are taxiing and loosing tires or tipping it over, slow down. 20 mph on the straight taxiways (which you can bump up to 30 if you want, but I usually stay around 20) with about 5-10 MPH on the turns should be just fine.
