I use AFPD on a daily basis, 1 hour minimum. I mostly use it to practice new 3D manouvers and IMAC sequences, but lately I've been usig it to develop my own scale jet manouvers. For 3D trainig it has been great. My R/C YAK 54 hovers a lot easier than in the Sim. Also, my model F-16 is so much easier to land than in the sim.
