I believe he said a whil ago that he has a whole bunch of 16F84s on hand, and since this is a hobby project he doesn't want to buy another chip. On the other hand if he is only doing a single channel R/C servo controller most any PIC should do fine. I am not familliar with the 16F84 but I am sure I could do it easily with the 16C54's I use. If I needed a doual channel controller I would use two 16C54s!
