Ok Marvin, tricky question but I will try to do my best.

A-4 definitely the fastest of the three with P-60 Power. A little more agile with the delta wing and small tail, and the new airfoil we used has proved to be much more stable at high angle of attack. This along with mixing crow in the landing configuration has made a substantial impact on the slow flight of this plane. That being said, I still would not classify this model as a trainer of any sort. An experienced jet modeler can adapt in a flight or two, but still may be a little zippy for the beginner to successfully earn his/her waiver on. Definitely my choice as favorite P-60 powered jet hands down, I have always loved the look of the A-4 and with the way this one fly’s its sealed its place in my heart.
F-16 probably wins for all around plane, because it has more wing area, gets a little extra lift from the fuse, very easy to fly, very stable in high alpha and will literally stand on its tail and hover with a slight headwind. This plane is a complete redesign from the balsa version, and has also adapted a new airfoil that allows it to fly much faster while still maintaining very stable slow flight. The scale detail is a major “WOW” factor, and the gear door option just puts the icing on the cake. The landing gear design and placement also eliminates any of the poor handling characteristics that usually follow narrow gear aircraft. This along with being very sturdy, and easy access to the gear mounts in the fuselage make it much more serviceable if by chance there happens to be a bad landing. The landing gear has been Tam tested this weekend, and has made it through with flying colors.
The T-45 I would classify as a basic trainer. The only thing easier to fly then this jet is a Boomerang, or possibly Ali’s Cougar. It has a sport plane style wing, large flaps, and with its size flew amazingly well on a P-60.

Hope this answers your question Marvin please let me know if I missed anything.
Take care,
Dave
